，用的时候要JOIN 3，4个TABLES,非常慢，DENORMALIZED了WEB快多了，数据库发展的
那么快，多数BUSINESS RULE都可以在数据库SIDE实现，而且PERFORMANCE也可以控制。 | y****9

Oracle database and application domain and design logic, he or she is
willing to share knowlege and being honest with DBA.
The most stressful time being a production DBA is troubleshooting production
performance problem in a limited time with many eyes watching on you. Many
time it turns out to be application problem, having a cooperative dev team
is essential to get the job done.
Working over time/ in off hours/ with extra hours - that is DBA life, not
really a difficult thing.
fyi, I am doing nothing else but being a production DBA in my current job.
