Rational Programming Patterns for System z

The architecture of Rational Programming Patterns for System z (RPPz) is centered around three primary components: the Pattern Designer, the Code Generator, and the Runtime Environment. The Pattern Designer is a graphical user interface (GUI) that allows developers to create and modify application patterns. These patterns define the structure, behavior, and data access methods of the application.

The Code Generator is a core component that translates the patterns defined in the Pattern Designer into executable COBOL or PL/I code. It handles tasks such as generating database access code, implementing business logic, and creating user interfaces. The Runtime Environment provides the infrastructure for running the generated applications on the z/OS platform.

Communication between these components is primarily internal. The Pattern Designer interacts with the Code Generator through pattern definition files. The Code Generator produces code that runs within the z/OS environment.

RPPz does not use a specific database or storage mechanism; instead, it generates code that interacts with databases like DB2. Network requirements are minimal, as the components primarily interact locally. The generated applications can be monitored using standard z/OS monitoring tools, such as IBM Z OMEGAMON.

Security is handled by the underlying z/OS platform, with developers incorporating security measures within their patterns and generated code.
