Announcing the first Big Data Developer Day. A full day with two tracks and hands-on on all things Big Data at Oracle!!
In the first post of this series, I discussed advantages of using a Data Vault over a replicated ODS. In this post I am going to discuss Data Vault and the more classical approach of a Kimball-style dimensional (star schema) design. To be clear upfront, I will be comparing using Data Vault to using dimensional for [...]
