1. Scope

This section defines the scope of the project by defining and describing the System, the major functions of the application, and the database.

1.1. System Description

Taylor’s Professional Services, a technical and engineering staffing service, wants a web site developed to enable their customers to complete a staffing request over the Internet as well as providing their clients with a list of potential candidates based on experience, education, salary, and location. There are two areas of the website. One area will allow the clients to search for the potential employees. While the other area will be available for TPS staff members to update their resumes and picture through the web site.

In addition, the web site has a layout that is easy to use. The layout includes a log-in screen that allows clients to access the client area; staff to access the staff area; and the contract manager to have full access to the site. Furthermore, a client will be able to select up to three potential staff members and submit the request. After a client has submitted a staff request order, the system will generate an automated response message informing them that “the contract manager will validate your request within 24 hours of receipt”.

1.2. Major Software Functions

TSP1: Web site login – This is where a user can enter in their credentials. When the user presses the login button the web site will validate the credentials with the

3 | P a g e



information in the database and either return an error if data is invalid or move to the main page area.

TSP2: Client Area – Where Clients and Contract Manager can access information on staffing requests.

TSP3: Enter Staff Request – Where the Clients can select up to three potential staff members based on the location of work, type of work, and salary. Once the Client submits a valid request they will receive a response that the contract manager will validate their request.

TSP4: Retrieve Staff Request – Where the Clients and Contract Manager can go to search and retrieve staffing requests by number. This information will show the staffing request and its status.

TSP5: Retrieve Contract Information – Where the Contract Manger can retrieve contract information. The Contract Manger can create, edit, or delete contract information.

TSP6: Validate Staffing Request – Where the Contract Manager can go to validate the Staffing request.

TSP7: Close Staffing Request – Where the Contract Manager can go to close the Staffing request.

TSP8: Web Site Database – This is where all the data for the web site will be stored.

TSP9: Staff Area – This is where the Staff and Contract Manager can add, edit, and remove personal information.

TSP10: Update Personal Information – This is where the Staff and Contract Manager can add personal information, resumes, availability, and pictures.

1.3. Database Description

The scope of the database allows for clients to easily search for jobs, upload resumes, and store this information for later use. The restrictions of the database are defined in the data dictionary. A major limitation to the database is the storing of resumes. The database is a fully operational MS Access Database acting as the Data Layer for our Website. Data validation is done through referential integrity rules based on common relational database design.

The relational database Microsoft Access will be used for this application. This option is chosen because relational database links more than one table together with

4 | P a g e



no duplication of any data, if the database is designed successfully. Using relational databases can also help us retrieve, sort, edit data in different ways.

The Database provides the following direct functionality:

o Creation of datao Updating of datao Insertion of datao Retrieval of data

The tables involved in the database include the following:

o Staff Tableo Client Tableo Login Tableo Staff SelectionTableo Staff Request Table

These tables are broke down to the following fields:

STAFF CLIENT LOGIN STAFF SELECTION

STAFF REQUEST

Staff ID Client ID User ID ID Staff Request IDLast Name Business Name User Name Client ID Client IDFirst Name Contact Person User Password StaffRequestID Type of WorkAddress Phone END TABLE Location LocationCity Email TypeOfWork ExperienceLocation Street SelectionDate EducationZip City Salary SalaryPhone State Choice1 StatusStartDate ZipCode StaffID1 Approval NumberEndDate ContractDate LastName1 DateOpenedEMail ClientType Choice2 END TABLEExperience END TABLE StaffID2Education LastName2Salary Choice3Profession StaffID3Availability LastName3Resume END TABLEPhotoEmployeeIDEND TABLE

1.4. Design Constraints and Limitations

The scope of the database is to allow for clients to easily search for jobs, upload resumes, and store this information for later use. The restrictions of the database are defined in the data dictionary. A major limitation to the database is the storing of resumes.

With web based environments, we are either trapped in a Linux or Windows web server environment, both of which cause a major setback with the design and implementation of a database system.

In a Windows environment, we are restricted to an ASP, ADO, Access, and MySQL environment. While in a Linux environment, we are even more restricted to a PHP, JSP/Java, and MySQL environment.

Our limited experience as a team in both of these scenarios could pose a serious problem. However, instead of regarding this as constraint or limitation, we regarded this as a way to look at it as a positive, building experience, where we can learn and face a challenge head-on and learn new ways to defeat the problems we may have to encounter.

Operating system requirements or limitations. Web browser limitations due to version or brand differences. Security Response times and processing Data storage limitations

The site has been designed to allow clients to search for staff, staff to place their information on the site to be searched, and allow contact managers access to the searches so that they can be completed. This is browser based so it needs to be kept clean and simple on all the page designs. Navigation should be uniform across all the pages so users can get to the sections they need to.

2. Design Description

This section provides an overview of the application design by providing a description of the data used and managed by the application, defining the flow of data through the system, describing the architecture of the programs within the application and defining how the components will interface.

2.1. Data Description

SCHEMA/ERD:

2.2. Data Flow

Data Flow Diagram Validating Staff Requests

The process “Register Staff” accepts staff information from staff members and inserts the staff information in the staff datastore. The process “Request Staff” is responsible for receiving information about staff requests to be offered by the client, validate the proposed staff request, and insert/update the staff request datastore

9 | P a g e



accordingly. If a proposed staff request is found to be invalid, a notification is sent to the concerned client. The “Edit Staff Info” handles changes in staff information (including changes in address, availability, etc.). The process “Search Staff Members” handles search requests for potential staff members for a particular staff request. The process, checks the staff request criteria (e.g., location or experience) from the staff request datastore. Then, the client draws on information stored in the staff datastore to generate a list that is sent to contract manager to be filled.

2.3. Program Architecture

User Login: This is where a user enters their login credentials. Then the login module checks the entered credentials against the database and allows the user to enter the requested area if their credentials are valid. If the credentials are invalid the user will receive an error message.

Client Area: The client area allows a client to enter a staff request and retrieve a staff request. All requests will be validated and checked against the database. The Contract Manager can login to the client area and retrieve contract information, validate staffing requests, and close staffing requests.

Staff Area: The staff area allows a staff member to update their personal information, resume, pictures, etc. The Contract Manager is also allowed to view, edit, and update staff information. All requests are validated and updated within the database.

Logoff Area: The Client and Staff areas allow the users to log out. All data retrieved and entered is added to or pulled from the database. The data flow determines how the database tables will logically pass data between them.

The client, staff, and contract manager all have access to the TPS site through the defined flow diagram, determining which tables and data have access to each other.

Specifically the detailed design includes the processing descriptions, use cases, interface descriptions, module uses and pseudo code on how the module functions.

These functions include:

Client Login, Staff Login, Contract Manager Login, Staff Info, Staff Request Info, Staff Request Verification, Staff Info Verification, Client Info, Client Info Verification, Update Staff Info, and Update Staff Request Info.
