Journalizing Knowledge Modules (JKM)

Journalizing Knowledge Modules (JKM)

JKMs create the infrastructure for Change Data Capture on a model, a sub model or a datastore. JKMs are not used in interfaces, but rather within a model to define how the CDC infrastructure is initialized. This infrastructure is composed of a subscribers table, a table of changes, views on this table and one or more triggers or log capture programs as illustrated below.

1.7 Service Knowledge Modules (SKM)

SKMs are in charge of creating and deploying data manipulation Web Services to your Service Oriented Architecture (SOA) infrastructure. SKMs are set on a Model. They define the different operations to generate for each datastore's web service. Unlike other KMs, SKMs do no generate an executable code but rather the Web Services deployment archive files. SKMs are designed to generate Java code using Oracle Data Integrator's framework for Web Services. The code is then compiled and eventually deployed on the Application Server's containers.
