I like to experiment and play with new shiny objects. LinkedIn recently added a blogging platform to their site. I’ve decided to publish a little thing on how to do a better job on writing abstracts for conferences. A few disclaimers: I’m no expert, but I write and review a TON of these Many people tell me they want to submit a talk, but don’t have the experience to do it up ‘right’ I mentioned…
One of the new Database 12c features is the SQL Translation Framework. Developed primarily to help customer migrate their 3rd party applications and databases to the Oracle stack, it also offers application DBAs an opportunity to substitute poorly performing SQL with their own custom SQL – without changing the application itself! Do I have your attention now? Kerry Osborne wrote an excellent post on the topic using a closer-to-real-world example and shows the pl/sql package…
