The tabular representation of code as business-relevant rules is much easier to understand than the legacy code, where
business logic is intermingled with low-level and technical code. To aid business analysts in reviewing
business rules, the implementation-oriented and sometimes cryptic terminology extracted from the legacy
code can be automatically replaced by more easily-understandable business terminology. In addition to
rules tables, business rules are provided textually and as a graph of the rule execution.
Business rule extraction identifies the business purpose of an application and presents it in an easy-to-understand format, making the application more understandable for non-technical reviewers in the absence of up-to-date requirements documents.
Many companies are re-examining their business processes from the top down to streamline inefficient processes that have evolved over time. Business rule extraction complements this analysis by providing a view of which processes the system implements and how this is done.
When a legacy application is migrated manually to a COTS system, developers typically are not familiar with the legacy languages such as COBOL. Business rule extraction represents the essence of the legacy system in an easily understood format.
In order to support application maintenance by non-programmers, applications can be migrated to rules engines. Updraft’s modernization factory translates the extracted business rules to notations used by a selected rules engines such as DROOLS or ODM.
A sovereign social insurance administration asked Updraft to extract the business rules implicit in their legacy claims-processing system. Updraft separated the business logic from low-level code that was intermingled, and represented system behavior in an easily understandable rules table – allowing business analysts to rationalize the legacy system against their updated business processes.
