Top-Down Application Building

If you are developing a new application, a top-down approach is a good way to design the functions for your application. This approach, which assumes that your data model and access paths are defined, includes

• Identifying the functions to be called from points in processing
• Working top-down to define functions and function parameters as needed
• Specifying top level constructs and the logic flow of user points
• Filling in user point details

• The functions you will select for your application, see the chapter Defining Functions.
• Getting the best performance from your application, see the chapter Tailoring for Performance.
