A New Database Bug  -  Making a play on words, I'm writing about a new grid based data engine called Cockroach DB. Check it out.

Final Thoughts on Business Rules  -  Today I'm providing a summary regarding business rules implementation. I also have a challenge you may want to take on.

Business Rules Outside SQL  -  Many individuals left great comments on my editorial on placing business rules outside of the database. Today, I'm providing a couple real world examples of putting business rules in another tier that were a stellar success.

It's Time to Break Your Business Rules Out of Your Database  -  For years we have held on to the best practice of keeping your business rule implementation close to the data, by enforcing them in a SQL database.
