Low-Level Design

In the low-level design phase, a detailed design of the software modules, based on the high-level design, is produced. In addition, the team lays down specifications for various software modules of an application. Modules defined in the high-level design phase are used to create a detailed structure of a system. The system contains subsystems, which are partitioned into one or more design units or modules.

In the low-level design phase, the flow of the different modules in the Customer Maintenance project and the interactions between various interfaces are defined. The flow and the interaction between the interfaces are shown in the following figures.

The Form1 Module

The Form1 module deals with Form1. Figure 7-7 shows the flowchart and the interaction of Form1 with the other modules.
