Developing applications

You can develop applications in COBOL, Java™, Node.js, C, C++, PL/I, Assembler, and REXX languages. CICS® provides application programming interfaces (APIs) so that applications can access CICS services and data in other products, such as VSAM and Db2®.

Application development involves several stages:
  1. Design
  2. Develop
  3. Debug
  4. Deploy

These stages are covered in detail in this section.

The CICS catalog manager example application helps you understand the best practice that you can apply when connecting CICS applications to external clients and servers.
