How can Application Discovery and Delivery Intelligence (ADDI) help in documenting your current Mainframe Application portfolio to benefit a big productivity gain in getting a much better understanding of your legacy source code. Next to this, it has mechanisms to find Business Terms in the Legacy code and to extract business logic that is related to these Business Terms to isolate them as API's or to a Business Rules Management tool.
