Well, let's illustrate by example.

In recent years, the networks of developers, integrators, consultants, and manufacturers committed to supporting database systems have morphed from one-on-one partnerships into huge ecosystems in which they have become interdependent on one another, and are subject to cross-winds of trends and shifts that are shaping their networks. Nowhere is this more apparent than the huge ecosystem that has developed around Oracle. With Oracle's never-ending string of acquisitions, new functionality, and widespread adoption by enterprises, trends that shape this ecosystem are certain to have far-reaching effects on the rest of the IT world. Concerns that percolate through the ecosystem reflect — and influence — broad business concerns. New paradigms — from cloud computing to big data to competing on analytics — are taking root within the Oracle ecosystem long before anywhere else.

If you've worked with relational database systems for any length of time, you've probably participated in a discussion (argument?) about the topic of this month's column, surrogate keys. A great debate rages within the realm of database developers about the use of "synthetic" keys. And if you've ever Googled the term "surrogate key," you know the hornet's nest of opinions that swirls around on the topic. For those who haven't heard the term, here is my attempt at a quick summary: A surrogate key is a generated unique value that is used as the primary key of a database table; database designers tend to consider surrogate keys when the natural key consists of many columns, is very long, or may need to change.

SQL Server 2012 includes a lot of new and exciting features. One feature that has caught the imagination of many in the user community is the high-performance feature called Columnstore Indexes. (Incidentally, it was also known as Apollo during its beta cycles). Columnstore indexes, as their name implies, store indexed (and always compressed) data contiguously in columns, rather than in standard format where the data is stored contiguously on 8Kb data pages according to the rows in which the data resides. Because of their structures, columnstore indexes speed up read-heavy operations like data warehouse queries from factors of 10x to 100x.

A database design may occasionally show evidence that it lacks proper prioritization. Data models should express truths about the business, or about the universe of discourse. But in expressing business truth this does not mean a data model should express absolutely every truth that anyone might conceive. Some relationships are significant while other relationships are not. And as a general rule, database design is not an exercise in trivial pursuit. Insignificant truths only clutter up a design, increasing complexity, causing users' eyes to glaze over more quickly, and adding no real value towards the endeavors of the enterprise.

Throughout the 2000s, a huge number of website developers rejected the Enterprise Java or .NET platforms for web development in favor of the "LAMP" stack - Linux, Apache, MySQL and Perl/Python/PHP. Although the LAMP stack was arguably less scalable or powerful than the Java or .NET frameworks, it was typically easier to learn, faster in early stages of development - and definitely cheaper. When enterprise architects designed systems, they often chose commercial application servers and databases (Oracle, Microsoft, IBM). But, when web developers or startups faced these decisions, the LAMP stack was often the default choice.
