Oracle launched their Oracle Big Data SQL product earlier this week, and it’ll be of interest to anyone who saw our series of posts a few weeks ago about the updated Oracle Information Management Reference Architecture, where Hadoop now sits alongside traditional Oracle data warehouses to provide what’s termed a “da
Tree bindings can be very handy, for example to combine details in the same row as the master. Let’s assume we have the following starting point based on the HR schema:
Default method’s (aka Defender methods) in interfaces are new in Java 8. They enable you to define a default implementation of a method in the interface itself.

Here’s a code example :
In this post, the finale of the four-part series “GoldenGate and Oracle Data Integrator – A Perfect Match in 12c”, I’ll walk through the setup of the ODI Models and start journalizing in “online” mode. This will utilize our customized JKM to build the GoldenGate parameter files based on the ODI Metadata and deploy them to both the source and target GoldenGate installation locations.

Yesterday a Thank-You letter from their director arrived. “My […]

Hopefully readers can find some time between World Cup matches to try integrating ODI and GoldenGate on their own!
