Your post - it's just so generic that I don't know how anyone other than you could answer it. What does "bad" mean to you? What specific Oracle products are you talking about? How much do you know about the data warehouse design or the OLAP design? What is it that you are doing exactly? You just are way too general - Oracle probably makes 500 products and is a multi-billion dollar enterprise-focused company. If all Oracle products were "so bad" (as typified by "so many problems"), surely they wouldn't be such a massive company, no?
