Contents of a Specification

A significant part of an application system should be implicitly defined by the OS/400 standards, the CA 2E standards, and standards followed by your tools. To specify a system for user approval, you will need the following:

• A description of the data model, in particular the database files and what they represent. This may include entity relation, dataflow, and other diagrams.
• A description of the user interfaces, in particular the layouts of menus, displays, reports, and a description of the parameters of commands.
• Notes on the processing specific to the application, including calculation, long algorithms, and recovery considerations.
