Figure 4.1 Process of the Manual Scheduling

The figure shows the existing system of AMA Computer College Lipa. The administrator will gather the data needed for the manual process of Scheduling. After gathering the data the administrator will manually do the schedule.

Figure 4.2 Process of the Proposed System

The figure shows the content of the proposed system. Once the user entered to the system, the system is ready to accommodate the File Maintenance, Schedule Management, Schedule Browser and Reports.

Prospective User

The Administrator will act as the primary user of the proposed system. The primary user has access to all the features of the system which includes file maintenance, schedule managing, schedule browsing and generating reports.

The primary user can add, edit, update and delete different transactions of all the features mentioned above. The user also allows to print all the reports that was produced by the system.

Components of the Proposed System

In Software Product Analysis in Chapter III, the proponents discussed the different possible software that can be used in making the proposed study. Among all those software, the proponents decided to chose the SQL server 2008 for database, and Visual Basic .Net 2005 as the programming language. The proponents prefer to use the SQL Server 2008 over other databases it provides much faster Full-Text Search capability and much faster processing once SQL Server 2008 features are used. In addition, SQL Server 2008 provides for more efficient storage of data and indexes including filtered indexes, wide tables, sparse columns, and page level compression.

In terms of programming language use, the proponents used Visual Basic.Net 2005 because the Visual Basic.Net is one of the most popular languages used in the software development industry. VB.Net provides managed code execution that runs under the Common Language Runtime (CLR), resulting in robust, stable and secure applications. VB.NET is free threading against the

VB single-threaded apartment feature. All features of the .NET framework are readily available in VB.NET. VB.NET is totally object oriented. This is a major addition that VB6 and other earlier releases didn't have. Security has become more robust in VB.NET.

System Design

DFD (Data Flow Diagram) is used by the proponents to show the graphical representation of the flow of data through the system. This is also used in visualizing of data processing. The context is the summary of DFD of the existing and proposed Data Flow Diagram (DFD). This is the commonly used system modeling tools, particularly for the operational system in where the functions are paramount important and more complex than the data that system manipulates. The context is the summary of the Data Flow Diagram (DFD) of proposed system. The DFD (Data Flow Diagram) is shown in figure 4.1 Data Flow Diagram of the Proposed System
