What is Reverse-engineering and What are the types of Reverse-engineering ??

Reverse-engineering


A new model is created with no datastores. Reverse-engineering is the process that populates the model in Oracle Data Integrator by retrieving metadata from the data server containing the data structures. There are two different types of reverse-engineering:

Standard reverse-engineering uses standard JDBC driver features to retrieve the metadata. Note that unique keys are not reverse-engineered when using a standard reverse-engineering.

Customized reverse-engineering uses a technology-specific Reverse Knowledge Module (RKM) to retrieve the metadata, using a method specific to the given technology. This method is recommended if a technology specific RKM exists because it usually retrieves more information than the Standard reverse-engineering method. See the Oracle Fusion Middleware Connectivity and Knowledge Modules Guide for Oracle Data Integrator for a list of available RKMs.
