Delta DETAB helps software developers to specify complex issues in an easily understandable way and to efficiently implement the decision logic. The use of Delta DETAB simplifies the communication with the business departments and reduces development and maintenance costs.

Decision Tables for a Clear Presentation of Complex Issues

Decision tables are an excellent method to clearly and understandably specify complex issues, processes and system of rules. They are used to present complex dependencies between several conditions and the individual actions to be performed in a clear, complete and consistent manner.

Decision tables are much easier to understand and validate than code, so they are often used for the specification of complex systems. As they are language-neutral as well, they simplify the communication and coordination between the technical departments and the software development. In addition, decision tables facilitate the development of test cases and the business rule management.

Delta DETABDelta DETAB for the Automatic Conversion into Error-free Code

Delta DETAB supports the decision-table technology in the analysis and programming. The automated, generative implementation of decision tables into target-platform-specific, optimized source code using DETAB accelerates and simplifies the software development:

  • Strong reduction of the testing and maintenance effort:
    Comprehensive examination of the decision tables for completeness, consistency and contradictions, redundancies, overlaps, ambiguities, and many more.
  • Efficient implementation:
    The corresponding error-free, optimized source code for the desired target platform is automatically generated in COBOL or PL/I.
  • Test aids
    simplify the troubleshooting and documentation of tests.
  • Exact and clear documentation

Our customers successfully use Delta DETAB to easily specify complex decision logic, simplify the communication with the business departments and to reduce the development and maintenance costs.


As with Delta ADS, we distinguish between the development platform where the development is performed and the runtime platform the applications are generated for and run productively.

The platform support of Delta DETAB is continuously extended. If your platform is not listed below, please contact our sales representatives to discuss your specific requirements.

Development Platforms for Delta DETAB

Delta DETAB can be used for the development on different platforms – stand-alone as well as an integrated part of the development system Delta ADS.

Input for standalone usage is a COBOL or PL/I program that includes decision tables. Delta DETAB is then used as a pre-processor that translates the decision tables into the appropriate COBOL or PL/I code for the desired target platform.

NEW: As a component of Delta ADS, DETAB is already available for the development on Eclipse for some time. Now we also provide DETAB standalone for the integrated development on Eclipse. Thus, the advantages of the modern development environment can now also be used for DETAB stand-alone, and the development of decision tables with DETAB can seamlessly be integrated into current processes.

Development Platforms

  • PC systems:
    Microsoft Windows - optional integrated in Eclipse or Microsoft Visual Studio
  • Unix / Linux – different manufacturers
  • Mainframe:
    HP NonStop, Guardian
    IBM z/OS
