Big data tool vendors try to downplay the notion that data warehouses and data marts still need to exist, even in a big data world. Relational DBMSs are painted as "old-fashioned," "yesterday," and "inadequate." They beckon potential customers to take a dip in the refreshing data lake. The fact that big data, in all of its glory, is only part of a larger business intelligence solution is getting lost in the dialog.

It is fair to say that relational theory is the only solid framework for establishing a rational expression of data that falls anywhere inside the boundaries of formal logic. As people continue to laud the "death of relational" by coming up with one or other "new" physical implementations of coding or data engines, from object-oriented, XML, columnar, or anything else one might name, the primary short-coming is that these are physical implementations that avoid having any formalized logic underpinning them.

"On occasion, the inmates actually do take over the asylum. Similarly, business personnel can be defeated by their IT peers," writes Todd Schraml. Although some might argue that such an unexpected role reversal cannot happen, it may indeed occur when data architects skilled in their craft can identify the options that help achieve the business goals, versus those alternatives that stifle the business goals.

Competitive differentiation in the mobile space depends only peripherally on the hardware - all modern smartphones have similar processing, display and networking capabilities.

Lists help us to remember, impose order upon tasks, and provide guidance. Some lists have taken on great importance in the world and in our lives. The Bill of Rights is such a list. So is the Ten Commandments. But although we use lists to administer, program, and maintain our databases, there really is no overarching list of "things you should (or should not) do" to ensure an effective, accurate, well-designed database. So here is the list of Ten Database Commandments.
