Reveries on Database Systems and Hiring

First, an apology is in order, I have to admit I've been on blogging hiatus for over a month, and hopefully you'd understand that my enthusiasm for blogging has not waned. My blogging hiatus is just that, a brief hiatus (and tons of events happened since then, like I'm in between jobs as of this writing, enjoyed the Westlife concert with my better half, had an opportunity to step back and see where I am and where I want to go to, Apple's Steve Jobs passed away a day after my birthday, and most importantly, got me Dr. Dobb's Essential Books on Algorithms and Data Structures CD-ROM Release 2 CD as gift for my birthday from my youngest sister), and what better way to blog actively again than to talk about my favorite IT infrastructure, the database system (could even be the most important!) and since I'm currently in between jobs, about hiring IT professionals.

But first let me relate an incident about a friend's newly bought desktop PC, built from choice components, you can consider this computer a bazooka to kill a fly off the wall. The problem was that my friend later updated the BIOS firmware and the new PC has since had mysterious behavior like shutting down for no apparent reason. In short, that BIOS firmware upgrade cost my friend wasted time bringing the rig to the shop to be fixed, good thing the PC is still within warranty and replaced. Moral of the story is: if it isn't broken, you have no reason to fix it, so don't mess with it, same goes with the database back-end of your application.

What You Should Learn About Database Systems

If IT meant Information Technology, then arguably and syntactically having relevant information is first and more important than the technology that delivers it. Information may be stored in a text file, a word processor document, a spreadsheet, a presentation, or an XML file, but for easier, faster and reliable search and retrieval, the database management system rules.

Unfortunately, I have observed that most books available in local stores in my so-called third world country tragically lack the fundamentals that should be learned to maximize the beneficial use of database management systems or (DBMS). Worse, many are tied to proprietary systems like Oracle and Microsoft SQL Server, which are usually tied to particular (and usually expensive) platforms (i.e. Windows or Solaris only), will almost cost you your soul to put into hands on practiality, and worst, subject to whimsical changes and features that the vendor may deem important to differentiate their product from the rest; resulting to obsolete skills for outdated systems.

Michael Jordan didn't become the greatest basketball player by just going straight for the hoop and shoot the second he has the ball on hand. By the same principle, what should you learn about database systems?
