Not All Databases Are Created Equal
Not all databases are created equal. No kidding. That is like saying that not all cars are the same, or not all buildings are the same. But somehow, "judging" databases isn't so easy. First off, there is no tangible "tire" that you can kick when evaluating databases or data sources. Actually, kicking the tire is quite useless, even when you are inspecting an automobile. Can you really gauge the car's handling, balance, fuel efficiency, comfort, speed, capacity or reliability based on how it feels when you kick "one" of the tires? I can guarantee that your toes will hurt if you kick it hard enough, and even then you won't be able to tell the tire pressure within 20 psi. If you really want to evaluate an automobile, you will have to sign some papers and take it out for a spin (well, more than one spin, but you know what I mean). Then, how do we take a database out for a spin? That's when the tool sets come into play.
However, even when the database in question is attached to analytical, visualization, CRM or drill-down tools, it is not so easy to evaluate it completely, as such practice reveals only a few aspects of a database, hardly all of them. That is because such tools are like window treatments of a building, through which you may look into the database. Imagine a building inspector inspecting a building without ever entering it. Would you respect the opinion of the inspector who just parks his car outside the building, looks into the building through one or two windows, and says, "Hey, we're good to go"? No way, no sir. No one should judge a book by its cover.
In the age of the Big Data (you should know by now that I am not too fond of that word), everything digitized is considered data. And data reside in databases. And databases are supposed be designed to serve specific purposes, just like buildings and cars are. Although many modern databases are just mindless piles of accumulated data, granted that the database design is decent and functional, we can still imagine many different types of databases depending on the purposes and their contents.
