The organizers wanted an in-person event. While you can access some chosen content remotely an in-person event has a lot of advantages, like getting in […]

Martin Fowler reviewed this article and published it on his website. Hence it is highly visible. I generally agree with the approach. But I cannot agree with […]

View-API for JOOQ Application

In this blog post I show how to build a read-only view-API for Oracle’s HR sample schema. And I will use this view-API in a JOOQ application. This application will fully comply with the Pink Database Paradigm (PinkDB).

Some people think that using APEX and PL/SQL in their database application is SmartDB. But it is not that simple. Bryn Llewelyn defined the term “Smart Database Paradigm” (SmartDB) in his talk Guarding […]

How to Prove That Your SmartDB App Is Secure

If you are guarding your data behind a hard shell PL/SQL API as Bryn Llewellyn, Toon Koppelaars and others recommend, then it should be quite easy to prove, that your PL/SQL application is secured against SQL injection attacks. The basic idea is 1) that you do not expose data via tables nor views […]
