COBOL data models and execution options

You can define an execution object model (XOM) from Java™ classes or a COBOL copybook. You can also deploy rules in various ways for execution on z/OS®, and share rules between Java and COBOL platforms.

Object model and deployment options
You can choose which type of object model to use for your rule project, and which deployment option suits your execution requirements.
Workflows that start from a COBOL copybook
To execute your rules in a COBOL application on z/OS, you can generate your XOM from a COBOL copybook.
Workflows that start from a Java XOM
If your rule project already contains a BOM generated from a Java XOM, you can adapt the BOM so that you can execute your rules in COBOL applications, as well as in Java.
Handling data type differences between Java and COBOL
You must make sure that the data types, and any calculations that are used with them, match the expected results of the COBOL application from which the rules were extracted.
