I understand and well aware of that. Having said that, I also often see companies purchase Oracle for technical and business reason. I went and saw myself first hand experience a multi-financial company that opted for Oracle (as opposed to SQL-Server, which they benchmarked) to build their financial system and they are pleased with that.

No argument between TDD, BDD, DDD, C# vs Java, Linux vs Windows, Commercial vs FOSS and all that crap. Just Oracle, PL/SQL, Forms, and Oracle Financial. There's no Java code at all around there. Pure "module" based. Testing is a lot easier vs to test your own "financial" module written in JEE.

I see it as more practical and suits the business well.

Of course if the business requires infinite customization (in the case of that crazy idea called Business Process Redesign), then maybe hiring a team of software developer is better than buying Oracle.
