Library Management System

1.1 Introduction.The aim of this project is to design and implement an online library, which will enable users to search for books and browse information about these books as the abstract, publisher information, cost, table of contents, etc. The database of the library based on one of the standardized systems for cataloging and classifying the books. We follow the standardization rules to assign subjects and sub-subjects codes, and to classify books under subjects and sub-subjects.

1.2The curnt system it is manually system where librarian have to process every thing manually from organizing the books and place them in the right place write shelf to retrieve them for the library visitors and that is overwhelming consuming process 1.3 Problem for the current system.Retrieving books from a library is very important for many peoples. The main problem is to define whether this book is exactly what the user wants and where this book resides in the library (to go and pick). And that with be source of some of these hinders in books searching in library1-

Wasting a lot of time looking for the book in the wrong location in the library Use the wrong search item and ending up with the same title for more than author6

3-

Misallocate books in the wrong section the wrong shelf Search process consume allot of the librarian time as well as the visitor and it could be overwhelming for the librarian specially if they have to deal with more than one visitor at the time

4-

There is a need for designing an advanced search engine that searches a library database and returns a complete book record, including the shelf number on which the book resides

1.3 System Objectives. Design and implement a library database based on a standard library classification system. Build an advanced search that can help for the best handling of user queries, this search should handle different search types like searching by author, title, subject, format or any combination of them, or searching by ISBN, or Publisher and Publication date. The search result should contain

information about the exact location of the book. Build the interface between the online screens and the library database system.

1.4 Project Scope.Project scope will be contains the following activities: Reception activities. Sales transactions. Accounting system. Book store follow up. Using internet facilities to connect all branches together.

Activities to be covered in our project The following is the activities that will be covered in our project scope: Maintain book information.8

Library Management System

Maintain publisher information. Maintain author information. Handel search request. Handel retrieval operations like:-. - List all books with specific title. - List all books with specific author name. - List all books classified under specific sub-subject. - List all books with any combination of title, subject and author. - List all books published by a certain publisher. - List all books published in a certain date. - Retrieve a book with a given ISBN. - List all books belong to a certain series.

Project approach.

To solve our problems in this system, we will use the following structured approach to achieve the system goals using the next steps in analysis and design phases:-

Analysis phase:

Library Management System

In this phase we want to analyses the system and tray to explain the moving data between different components of the system. * Prepare the context diagram, which it is the highest level view of the system, it contains only one process and a number of data flows and also a number of sources. It is an overview of an organizational system that shows the system boundaries, external entities that interact with the system, and the major information flows between the entities and the system. * Data flow diagram (DFD). It is a logical model of the system. These diagrams have a notification for each of the components of the system, they also have a notification for representing different level in a hierarchy of detail used to describe the system. *use case diagram use case in a use case diagram is a visual representation of a distinct business function in a system. For10

example, In a banking application, a deposit function represents a use case *Class diagram Its the conceptual model ; and its use conceptual ion to visuals the basic concept of the system in the analysis stage

Design phase: * Prepare the (ER) entity relationship diagram, which it is a data model that determines the relationships between several entities in the system. * ER to relational data model mapping. * Normalization. The normalization process takes a relation schema through a series of tests to certify weather it satisfies a certain normal form. *Sequences diagram It call interaction diagram too ;in it the transformation for the analysis requirements to the its final functionality in the destine stage11

2.3 Context Diagram:The context diagram is the highest level view of the system, it contains only one process, no data stores, and a number of data flows and also a number of source/sinks. The single process represents the entire system and its labeled o. The source/sinks represent its environmental boundaries. Since the data stores conceptually inside the one process, no data stores appear on a context diagram. It is an overview of an organizational system that shows the system boundaries, external entities that interact with the system, and the major information flows between the entities and the system. In the figure, the context diagram of the System is shown. It consists of the following entities and the following data flows. Reception: This source represents the first step to start functions of our system that this section meet the customer to give him the answers of different questions he needs. Administration: This source represents the main department in library which responsible12

for managing all the information which the system needs. Cashier: This section responsible for customers payment and issue the bills. Data flow: Customer request: this request from user to reception to inquiry about certain book with little information about this book, reception clerk will search and replay to customer about his needs in suitable time. Bill: prepared by cashier for all items purchased by customer using the information system which contains information about all items in the library like item description, quantity, item price and total value for bill. Statistical reports: prepared by computer department to help the mangers in the library to take a suitable decisions in the suitable time.

3.2 Notation about DFD.First, Data Flow Diagram is a logical model of the system, the model does not depend on hardware, software, data structure or file organization. It is a graphical picture of the logical system. It is an excellent tool for communication with user to explain the system for him. Data Flow diagram describes what happen not how is happens. Data Flow diagrams have a notation for each of the components of a system. They also have a notation for representing different level in a hierarchy of detail used to describe the system. This notation makes it possible to represent an overall view of a large complex system and a detailed view of a part of a system using the same notation. Parts of a system can be isolated in
