In the case of databases, I've seen poorly implemented Oracle solutions and wonderfully implemented MySql solutions. In general, it is management's responsibility to align the problem (or objectives), with the tool, and the skill of their staff. Right now my company is doing stuff on Oracle I couldn't even think about on MySQL. Fairly large Enterprise workloads in ETL, OLTP, and some emerging OLAP databases. Fortunately, I'm driving good revenue and have a talented/dedicated DBA team to support it. Basically, as my problem has evolved, so have the tools and people I use to keep pace.

I'm not a dba, but a developer. Oracle allows to put code and intelligence in the db, mysql does not. Oracle laughs at big ugly complex queries, while mysql shines at retrieving rows directly. However, the cost of joins, the inability to use indexes inside views or functions, and the unexplainable (or very time-hungry-to-solve) losses of performance are quite hard to work with. This changes my approach to programming. With mysql, performance is always a serious concern. With oracle, never. I worked with oracle for 10 years, and mysql for 2.
