    1. ABSTRACT OF THE PROJECT

    This Project includes all my learning work done during my six months Industrial

    Training at SPIC Microsoft. This web application is very useful for managing

    hostels detail. This is a very simple and easy to use web application which store

    information about hostels, wardens, students, seats in hostels, issued items,

    purchase details. We can filter the data according to hostelID, studentID, wardenID

    etc. We can maintain the data stored on the server.This web application is aimed at

    making data entry, management, updating, storage and retrieval easier and faster.

    The following objectives have been kept in mind:

    Efficiency:-We tried to involve accuracy, timeliness andcomprehensiveness of the system output.

    Cost: - It is desirable to aim for the system with a minimum cost subject tothe condition that it must satisfy the entire requirements.

    Flexibility: -We have tried that the system should be modifiable dependingon the changing needs of the user. Such modifications should entail

    extensive reconstructing or recreation of application.

    3. INTRODUCTION TO DOT NET

    The.NET is a web application frameworkdeveloped and marketed by Microsoft to

    allow programmers to build dynamic web sites, web applications and web services.It was first released in January 2002 with version 1.0 of the .NET Framework, and

    is the successor to Microsoft's Active Server Pages (ASP) technology. ASP.NET is

    built on the Common Language Runtime (CLR), allowing programmers to write

    ASP.NET code using any supported .NET language. The ASP.NET SOAP

    extension framework allows ASP.NET components to process SOAP messages.

    The .NET Framework, introduced by Microsoft in 2002, is a programming

    platform and set of tools for building and running distributed applications in the

    Internet era. It also contains an object-oriented class library and a collection ofreusable types (a type is a representation of data such as classes) that enable you to

    accomplish many common programming tasks such as file access, string

    manipulation, and database management. The class library is categorized into

    modules (referred to as namespaces) and includes types that support a variety of

    applications such as:

    Console applications Windows forms ASP.NET applications XML web services Windows services SQL Server applications Small device applications

    ASP.NET, the next version of ASP, is a programming framework used to create

    enterprise-class Web Applications. These applications are accessible on a global

    basis leading to efficient information management. The advantage that the

    ASP.NET offers is more than just the next version of ASP.

    In fact, C# is one of the .NET languages that Microsoft developed. The other

    languages that use .NET are Visual Basic .NET, J#, and Managed C++, in addition

    to languages developed by other companies. All these languages work under the

    .NET umbrella and use its libraries. Actually, you can write an application with

    modules written in different languages that support .NET.

    HISTORY

    After the release of Internet Information Services 4.0 in 1997, Microsoft began

    researching possibilities for a new web application model that would solve

    common complaints about ASP, especially with regard to separation of

    presentation and content and being able to write "clean" code.

    Mark Anders, amanager on the IIS team, and Scott Guthrie, who had joined Microsoft in 1997

    after graduating from Duke University, were tasked with determining what thatmodel would look like.

    The initial prototype was called "XSP"; Guthrie explained in a 2007 interview that,

    "People would always ask what the X stood for. At the time it really didn't stand

    for anything. XML started with that; XSLT started with that. Everything cool

    seemed to start with an X, so that's what we originally named it."The initial

    prototype of XSP was done using Java, but it was soon decided to build the new

    platform on top of the Common Language Runtime (CLR), as it offered an object-oriented programming environment, garbage collection and other features that

    were seen as desirable features that Microsoft's Component Object Model platform

    didn't support.

    Once the ".NET" branding was decided on in the second half of 2000, it was

    decided to rename ASP+ to ASP.NET. Mark Anders explained on an appearance

    on The MSDN Show that year that, ".After four years of development, and a series

    of beta releases in 2000 and 2001, ASP.NET 1.0 was released on January 5, 2002

    as part of version 1.0 of the .NET Framework. Even prior to the release, dozens of

    books had been written about ASP.NET and Microsoft promoted it heavily as partof their platform for web services.

    The .NET Framework is:

    Common Language Runtime provides an abstraction layer over theoperating system

    Base Class Libraries pre-built code for common low-level programmingtasks

    Development frameworks and technologies reusable, customizablesolutions for larger programming tasks

    The dot Net framework consists of two main components one of them is DotNet framework class library and another is CLR. The dot Net framework

    class library common for all dot Net language .We can use this to developdifferent application such as console applications, windows and Web Forms

    and Web Services.

    The CLR do some of the important task such as load the IL code of programat runtime. Compile the IL code in native code execute and manage code

    enforce security and type safety helps in thread support .The code that run in

    CLR is called unmanaged code. There is a layer which allows both manage

    code and unmanaged code to interoperate with each other.

    The CLR is combination of various components which provides the runtimeenvironment and runtime services for our application. These components

    load the IL code into runtime environment and runtime service for our

    applications.

    ASP .NET:

    ASP.NET is more than the next version of Active Server Pages (ASP). It provides

    a unified Web development model that includes the services necessary for

    developers to build enterprise-class Web applications. While ASP.NET is largelysyntax compatible with ASP, it also provides a new programming model and

    infrastructure for more scalable and stable applications that help provide greater

    protection. You can feel free to augment your existing ASP applications by

    incrementally adding ASP.NET functionality to them.

    ASP.NET is a compiled, .NET-based environment; you can author applications in

    any .NET compatible language, including Visual Basic .NET, C#, and JScript

    .NET. Additionally, the entire .NET Framework is available to any ASP.NET

    application. Developers can easily access the benefits of these technologies, which

    include the managed common language runtime environment, type safety,inheritance, and so on.

    ASP.NET has been designed to work seamlessly with WYSIWYG HTML editors

    and other programming tools, including Microsoft Visual Studio .NET. Not only

    does this make Web development easier, but it also provides all the benefits that

    these tools have to offer, including a GUI that developers can use to drop server

    controls onto a Web page and fully integrated debugging support.

    Developers can use Web Forms or XML Web services when creating an ASP.NET

    application, or combine these in any way they see fit. Each is supported by the

    same infrastructure that allows you to use authentication schemes, cache frequentlyused data, or customize your application's configuration, to name only a fewpossibilities.

    Web Forms allow you to build powerful forms-based Web pages. When building

    these pages, you can use ASP.NET server controls to create common UI elements,

    and program them for common tasks. These controls allow you to rapidly build a

    Web Form out of reusable built-in or custom components, simplifying the code of

    a page. For more information, see Web Forms Pages. For information on how to

    develop ASP.NET server controls, see Developing ASP.NET Server Controls.

    INTRODUCTION TO CRYSTAL REPORT

    Crystal Reports for Visual Studio .NET is the standard reporting tool for Visual

    Studio .NET; it brings the ability to create interactive, presentation-quality content

    which has been the strength of Crystal Reports for years to the .NETplatform.

    With Crystal Reports for Visual Studio .NET, you can host reports on Web and

    Windows platforms and publish Crystal reports as Report Web Services on a Web

    server.

    Advantages of Crystal Reports:

    Some of the major advantages of using Crystal Reports are:

    1. Rapid report development since the designer interface would ease the coding

    work for the programmer.

    2. Can extend it to complicated reports with interactive charts and enhance the

    understanding of the business model

    3. Exposes a report object model, can interact with other controls on the

    ASP.NET forms

    4. Can programmatically export the reports into widely used formats like .pdf,

    .doc, .xls, .html and .rtf.

    5. ABOUT THE PROJECT

    This project serves as a web application to handle the hostel system accurately and

    more efficiently. It is platform independent as it is a web based application.

    The main idea behind developing this application was to reduce the manual efforts,

    moreover making the system more easily accessible. This application reduces the

    problem of data redundancy with the help of normalization. It helps to maintain the

    records easily and is even less time consuming.

    As referred above the technology being used is Dot Net and we worked in web

    applications

    with ASP.NET as front end and SQL Server2005 as back end.

    SALIENT FEATURES OF PROJECT

    Integrated approach to the package helps in minimizing manual approach.

    User friendly package Timing and retrieval efficiency In-built validation checks to ensure accuracy

    Elimination of paper work Suitable help/error message for better user interface Updated information

    7. EXISTING SYSTEM

    Nowadays for handling these kinds of systems, a lay man does all the work

    manually. He needs to keep various registers or files so as to keep the details but it

    creates a mess for him whenever he needs to check a record, save another record,

    delete any record or update it. This also makes the data not so easy to understand.

    This increases the hardware cost and the maintenance headache. Moreover there

    also occurs certain kind of problems:

    Data redundancy. Loss of data. Difficult to access data. Time Consuming.

    Data Redundancy

    Data redundancy refers to duplication of data. In case of manually handling this

    system and maintaining the records, many a times same data is written at many

    places, so this repetition of data at various places can increase hardware cost,

    moreover maintaining such data becomes most difficult.

  • 7/31/2019 HostelProject 2223

    15/42

    15

    Loss of data

    In case of any kind of misplacing or if sometimes we lose the registers or files, it

    may lead to a great loss of data as no duplicate copy or a database is being

    maintained.

    Difficult to access data

    When the data is being placed at many places in small segments, it becomes very

    difficult to gather data from various places, moreover updating or deleting the data

    at each and every place.

    Time Consuming

    This process is very time consuming as to search for any data or for taking any

    kind of action, the person has to go through every data and check for each and

    every detail of the data.

    Record Management:

    Is very tangible job in manual database system.

    Inaccuracy:

    Some time there may be chance of inaccuracy. Existing system is not according to

    current demand.

  • 7/31/2019 HostelProject 2223

    16/42

    16

    No Report Generation:

    In Existing, system there is any automatic report generation facility.

    Inconsistency:

    In the existing system, there are no checks or constraints so; the duplication may

    make the data inconsistent.

    Unauthorized Access:

    There is no way to restrict unauthorized access to the data except putting the files

    under lock and key.

    Paper Wastage:

    Currently some tasks are done manually, its uses paper, hence not a cost efficient

    system and eco-friendly.

    Problem in Updating:

    As data are written on papers, the updating or any type of correction requires

    rewritten of information. There is no procedure for keeping duplicate record

    system.

    Due to above reasons the change in the existing system is required for the change

    we have to perform the feasibility study. The success of a system largely dependsupon how accurately the problem is defined and investigation. Until, the problems

    are clearly defined and evaluated, should we think about solutions.

    7. PROPOSEDSYSTEM

    Proposed system is expected to remove the problems of the existing system and

    provide value-added solution to the problem. Due to limitation in the existing

    system it is felt to switch over to a new system that covers all the possible aspects:

    Proposed system with objectives:

    Proposed System is automated and web based system so that's why it hasvery fast processing speed.

    Records management is very easy job in database. There may be not any chance of inaccuracy. Proposed system is according to current demand. In Proposed system there is automatic report generation facility. Security and privacy is possible by using user name and password. Data integrity is maintained and redundancy is reduced.

    Software System Attributes:

    Usability:

    The links are provided for each form. The user is facilitated to view and make

    entries in the forms. Validations are provided in each field to avoid inconsistent or

    invalid entry in the databases. Some forms consists Hyper Links, which provides

  • 7/31/2019 HostelProject 2223

    18/42

    18

    further details. Reports screen contains text boxes and drop down lists, so that

    reports can be produced.

    Security:

    Application will allow only valid users to access the system. Access to any

    application resource will depend upon users designation. There are three types of

    users namely Administrator and Warden. Security is based upon the individual

    user ID and Password.

    Availability:

    System will be available around the clock except for the time required for the

    backup of data.

    Portability:

    The application is developed in ASP.NET. It would be portable to other operating

    system provided .NET Framework is available for the OS. As the database is made

    in SQL Server, porting the database to another database server would require some

    development effort.

    Acceptance Criteria:

    The software should meet the functional requirement and perform the functionality

    effectively and efficiently.

  • 7/31/2019 HostelProject 2223

    19/42

    19

    A user-friendly interface with proper menus. Data transfer should be accurate and within a reasonable amount of time

    keeping in mind the network traffic.

    The system should not allow entry of duplicate key values. System should have the ability to generate transactional Logs to avoid any

    accidental loss of data.

    Log file should also be generated.

    8. Software Development Life CycleThis involves the activities in the production of the software system.

    Generally it can be divided into the following phases:-

    1) Feasibility study

    2) Requirement analysis

    3) System specification

    4) System and component design

    5) Implementation component design

    6) System testing

    7) Maintenance

    8.1.Feasibility Analysis

    A feasibility study is initiated to determine the performance and cost effectiveness

    of the proposed system and if it meets all the constraints, it is recommended in

    feasibility report. It measure how beneficial or practical the development of the

    system will be to the organization. It is a preliminary survey for the system

    investigation. Its aim is to provide information to facilitate a later in-depth

    investigation. A feasibility study is a test of a system proposal according to this

    work ability, impact on the organization, ability to meet user needs, and effective

    use of resources. It focuses on three major questions: -

    What are the users demonstrable needs and how does a candidate system meet

    them?

    What resources are available for given candidate system? What is the likely impact of the candidate system on the organization?

    Three key considerations are involved in the feasibility analysis.

    Economic Feasibility Technical Feasibility Behavioral Feasibility

    The feasibility study of the software is as follow:

    22/42

    22

    Economic Feasibility

    Economic feasibility determines the benefits and saving that are expected from the

    system and compare them with costs. Cost/Benefit analysis has been done on the

    basis of total cost of the system and direct and indirect benefits derived from the

    system. The total cost for the proposed system comprises of hardware costs and

    software costs. The main aim of economic feasibility is to check whether the

    system is financially affordable or not. The cost for the proposed system can be

    divided into two parts given below:

    Hardware Costs

    The hardware cost for the proposed system can be calculated from cost of

    hardware needed for the development of the proposed system. The hardware

    specifications for the system are given below:

    Personal Computer: The cost of the PC depends upon the configuration of the

    PC. The minimum specification assumed for the Pc is given below:

    P4 processor 256 MB RAM 40 GB free disk space MS Windows

  • 7/31/2019 HostelProject 2223

    23/42

    23

    Server: As the software is a client-server based application, thus an efficient

    server would act as the backbone of a good communication system. The minimum

    specifications are:

    Core2Dual processor 512 MB RAM 120 GB free disk space

    Software Costs: The Software costs for the proposed system can be calculated

    from the cost of software tools needed from the development of the proposed

    system. The software tools needed for the development of the system are given

    below:

    Microsoft Visual Studio 2008 SQL server 2005

  • 7/31/2019 HostelProject 2223

    24/42

    24

    Technical feasibility:

    Technical Feasibility centers on the existing system and to what extent it can

    support the proposed system. In this part of feasibility analysis we determined the

    technical possibilities for the implementation of the system. Two major benefits

    are:

    Improving the performance Minimizing the cost of processing

    This software is web based application. To develop the software the following

    technology will be used as per requirement:

    Language: ASP.NET Editor : Microsoft Visual Studio 2008 Database : SQL server 2005

    Behavioral Feasibility

    Behavioral feasibility estimates the reaction of the User staff towards the

    development of the computerized system. For the successful implementation of

    any system, the users must be impressed that the new system is for his benefit. So,

    the behavioral feasibility plays a very important role in the development of new

    system It reveals that whether the system is acceptable by user or not. If the user

    does not ready to use it, then it doesnt matter how best the system is or how much

    effort you are putting in its development.

    8.3 System Design

    The main objective of the system design is to make the application user friendly.

    After discussing with some of the technical persons, friends, guide; it was

    concluded that the design of the application should be 3 tier which means that the

    system will be developed in orientation to three things:

    Data:-

    It includes Database and Stored Procedures etc.

    Business:-

    It includes the logic that will actually process the data but it should be in the form

    of objects and classes that will help in providing the application components

    reusability, abstraction and other Object Oriented features.

    Presentation:

    It includes the front end that links the user to the whole system.Generally, it is said that if the design is made well, the whole system will work

    well. So, I have tried my best to put my effort on this phase properly.

    DATA FLOW DIAGRAM

    A data flow diagram is a graphical representation that depicts information flow and

    the transforms that are applied as data move from input to output. The data flow

    diagram may be used to represent a system or software at any level of abstraction.

    It has the purpose of clarifying system requirements and identifying major

    transformations that will become program in system design. So it is the starting

    point of the design phase that functionally decomposes the requirement

    specifications down to the lowest level of details. A DFD consist of a series of

    bubbles joined by lines. The bubbles represent data transformation and the lines

    represent data flows in the system.

    In fact, DFDs may be partitioned into levels that represent increasing information

    flow and functional detail. Therefore, the DFD provides a mechanism for

    functional modeling as well as information flow modeling.

    In the DFD, there are four symbols,

    A Square defines a source (originator) or destination of system data. An Arrow identifies data flow- data in motion .It is pipeline through which

    information flows.

    A circle or a bubble (or a oval bubble) represents a process that transformsincoming data flow(s) into outgoing data flow(s)

    An open rectangle is a data store-data at rest , or temporary repository ofdata.

    ER DIAGRAM:

    An E-R diagramcan express the overall logical structure of a database graphically.

    E-R diagrams are simple and clearqualities that may well account in large part

    for the widespread use of the E-R model. Such a diagram consists of the following

    major components:

    Rectangles: which represent entity sets

    Ellipses: which represent attributes

    Diamonds: which represent relationship sets

    Lines: which link attributes to entity sets and entity sets to relationship sets

    Double ellipses: which represent multi-valued attributes

    Dashed ellipses: which denote derived attributes

    Double lines: which indicate total participation of an entity in a relationship set

    Double rectangles: which represent weak entity sets

    Objects

    There are three main objects on an ER Diagram:

    1. Entities

    2. Relations

    3. Attributes

  • 7/31/2019 HostelProject 2223

    31/42

    31

    Entities

    An entity is a concept or object in the database. Entities are concepts within the

    data model. Each entity is represented by a box within the ERD. Entities are

    abstract concepts, each representing one or more instances of the concept in

    question. An entity might be considered a container that holds all of the instances

    of a particular thing in a system. Entities are equivalent to database tables in a

    relational database, with each row of the table representing an instance of that

    entity.

    Attributes

    The Supplier Name, Supplier Address, Telephone Number etc. A given attribute

    belonging to a given entity occurrence can only have one value. Therefore, if a

    supplier could have more than one address or telephone number then this should be

    determined before defining the attributes of that entity type. In this example the

    defined entity may require two or three address and/or telephone number attributes.

    It is the maximum practical instances of a given attribute that should be catered for

    in the entity type definition.

    Relationships

    Relations are the connections between two or more entities. Relationship lines

    indicate that each instance of an entity may have a relationship with instances of

    the connected entity, and vice versa.

    Mapping cardinalities, or cardinality ratios, express the number of entities to

    which another entity can be associated via a relationship set. Mapping cardinalities

    are most useful in describing binary relationship sets, although they can contribute

    to the description of relationship sets that involve more than two entity sets.Following are the types of cardinalities:

    One to one One to many Many to one Many to many

    8.4 SYSTEM TESTING

    Testing

    The system development life cycle involves the phases of testing and debugging

    after the requirement analysis, designing and coding. The project in question was

    tested , debugged and implemented successfully.

    Two strategies of software testing adopted for the new system are as follows:

    Code testing Specification testing

    LEVELS OF TESTING

    In order to uncover the errors present in different phases, we have the concept of

    levels of testing. The basic levels of testing are:

    Client Needs -----------------------------------Acceptance Testing

    Requirements--------------------------------- System Testing

    Design------------------------------------------Integration Testing

    Code Unit-------------------------------------UnitTesting

  • 7/31/2019 HostelProject 2223

    34/42

    34

    Code testing

    Code testing was carried out to see the correctness of the logic involved and the

    correctness of the modules. Tests were conducted based upon sample and live data

    as well. All the modules are checked separately for assuming correctness and

    accuracy in all the calculations.

    Specification testing

    It examines the specification stating about what program should do and how it

    performs under various conditions. This testing strategy is better strategy since it

    focuses on the way the software is expected to work.

    Unit Testing

    During the phase of unit testing different constituent modules were testing against

    the specifications produced during the design for the modules. Unit testing isessentially for the verification of the code produced during the coding the phase,

    and goal is to test the internal logic of the modules. The modules once tested were

    then considered for integration and use by others.

    White box testingDuring this phase of the testing phase SDLC, server developed was tested

    while considering a valid value corresponding to each of variable defined and

    corresponding to each function defined. During this phase values corresponding to

    each variable viz. URL filtering, word filtering and scheduling was done and

    desired results were obtained.

    35/42

    35

    Black box testingThis phase of testing deals with input/output testing. Black box testing was

    performed on the software developed, corresponding to valid inputs provided

    desired outputs were obtained.

    Integration Testing

    The next level testing that was performed is often referred to as integration testing.

    During this phase many unit tested modules were combined into subsystems,

    which were then tested. The goal here was to see if modules can be integrated

    properly. Here the emphasis was on testing interfaces between different constituent

    modules of system.

    Functionality Testing

    Here the entire software system was tested. The reference document for this

    process is the requirements document, and the goal was to see if software solution

    meets its requirements.

    This level of testing is essentially a validation exercise, and in many situation it is

    the only validation activity.

    Stress testing

    Proxy server developed for the specified purpose was testing under heavy load, i.e.

    a large no. of clients were made to sit in lab and were asked to send requests for

    loging in and then were asked to request for text on internet. System responded to

    request as desired.

    Acceptance testing

    Acceptance was performed in the real environment with realistic data of the client

    to demonstrate if the software developed is working satisfactorily. Here the main

    focus was on the external behaviour of the system; the internal logic of the

    program was not emphasized.

    TESTING OBJECTIVES:

    The main objective of testing is to uncover a host of errors, systematically andwith minimum effort and time. Stating formally, we can say,

    Testing is a process of executing a program with the intent of finding anerror.

    A successful test is one that uncovers an as yet undiscovered error. A good test case is one that has a high probability of finding error, if it

    exists.

    The tests are inadequate to detect possibly present errors. The software more or less confirms to the quality and reliable standards.

    8.5 SYSTEM MAINTENANCE

    System maintenance is an extremely important activity in the life of a software

    product that starts after the implementation phase. It is one form of change or

    rework. For proper maintenance of this system, I am spending a good time on

    documentation so that I or some other person can easily understand this system

    later when there is a need for maintenance.

    Because of the full development being Object Oriented and MS support with

    this product, this system can be easily connected to any other MS product with a

    very small effort. Except Web support, more modules can also be easily addedbecause of the 3 tier approach in design; any development or modification is as

    simple as creating a new application. We dont have to follow the old patterns; we

    can just start with a new style and add the new modules in to the older one without

    any problem.

    Corrective Maintenance:

    Almost all software that is developed has residual errors or bugs in them. Many of

    these Surfaces only after the system have been in operation, sometimes for a long

    time. These errors once discoveredneed to be removed, leading to the software to

    be changed. This is called Corrective Maintenance.

  • 7/31/2019 HostelProject 2223

    38/42

    38

    Adaptive Maintenance:

    Even without bugs, software frequently undergoes change. The software often

    must be upgraded and enhanced to include more features and provide more

    services. This requires modification of the software. This type of maintenance is

    known as the Adaptive Maintenance

    Perfective Maintenance

    This is actually the most common type of maintenance encompassing

    enhancements both to the function and the efficiency of the code and includes all

    changes, insertions, deletions, modifications, extensions, and enhancements made

    to a system to meet the evolving and/or expanding needs of the user. A successful

    piece of software tends to be subjected to a succession of changes resulting in an

    increase in its requirements. This is based on the premise that as the softwarebecomes useful, the users tend to experiment with new cases beyond the scope for

    which it was initially developed. Expansion in requirements can take the form of

    enhancement of existing system functionality or improvement in computational

    efficiency.

    Though efforts have been made to develop error free systems, but no system is

    perfect, room for improvement is always there. Thus proper documentation for the

    system has been done so that it will be easy to handle any breakdown or any other

    type of system maintenance activity.

    9. MODULES IN THE PROJECT

    Following are the modules of our application:

    Hostels Inventory Gate pass

    Hostels

    In this module, all the information regarding the various hostels of the college,

    their wardens, the floors in a particular hostel, the rooms on each floor, the mess

    etc will be provided. It will maintain the record of each and every room allotted to

    various students on a particular floor in a particular hostel. It will also maintain the

    information about the students. Moreover information about when a student is

    going to vacate, how many rooms are vacant and at which floor in which hostel,

    what kind of room a student is taking 1-seater, 2-seater or 3-seater, whether it is

    ordinary or AC.

    Inventory

    The inventory module will include the details regarding the hostel fee, mess fee,

    the issued facilities to the students like matrices, quilts, blankets, pillows, buckets

    and other necessary things. A full-fledged record will be kept and maintained for

    this. Using this record, it will become very easy for the warden and other

  • 7/31/2019 HostelProject 2223

    40/42

    40

    authenticated authorities to maintain a check on each and every thing. It will also

    become very easy to allocate various resources to the students, moreover

    maintaining the record of the resources.

    Gate pass

    Basically, this module will keep the record regarding the entry and exit of the

    students. Every student will be provided a gate pass id that will maintain a check

    on his/her entry and exit time. It will also maintain a record of the students coming

    late to the hostel than the prescribed time limit. Moreover a record is maintained

    whenever a student goes for a vacation or at home.
