The above systems are designed from the ground up using guidelines and application development tools from Microsoft Corporation. The Unified Modeling Language (UML) approach is adopted throughout the Software Development Life Cycle. The Systems are developed in three-tier client server Component Object Modeling (COM) architecture that includes the user (client) interface layer, the business logic (transaction process) layer, and the database management (SQL Server) layer. Each layer is kept separate from the others for security purposes, and completely integrated with each other through solid communications processes. This feature enables systems to support a large number of users without compromising performance. |
