Since over half a year I have made an adjustment in my course… nothing too dramatic, but still it has had some impact.
I have chosen the path of the more pure technique again. Not in a sense that I don’t manage anymore, though I don’t, but that’s more of a side effect
I have chosen the path of the more pure technique in a sense that the change from Closed Source software to Open Source software allows you to actually work with and solve things by creating solutions rather than trying to figure out how something, someone created for some issue, can reconfigured so it resembles a solution for your actual problem.
Okay… okay… this of course is exaggerated, but it serves to help think about the issue.
“No one ever got fired for buying Oracle” is one of the phrases I have heard numerous times over the past period.
Well, no… but it’s also no free pass to –sorry for the phrase– waste money on technology you either never going to use.
Over 80% of the installed base uses less than
20% of the technology they are paying for!
I have followed a number of the brightest mind in the industry (our industry, the database industry) for many years investing vast amounts of time in reverse-engineering pieces of technology that have been built, in order to explain certain behavior.
Of course, very necessary, no argument there, but wouldn’t it be so much more cool if this overwhelming amount of brain-power could be used to actually create stuff??
Open Source in stead of Closed Source…
The answer, I think!
Sure, I am raised with vendor created solutions, that was the default MO when I got trained. VMS, MS-DOS, HP-UX… (are you _that_ old, yes, I am _that_ old) and a number of applications that did the work.
Well, those days are gone… operating systems in data centers have (nearly) all been replaced by Linux distribution installs. And I mean like, as good as all of them.
Sufficiently stable, cost effective and they get the job done.
With the current explosive growth of Open Source databases, brace yourselves. Or rather, embrace!
All the exact same arguments that are there for Operating Systems apply. There is no difference, and you, the industry, chose! And you will choose this again. Simply because “it is good enough”, it is much more cost effective and it gets the job done.
The extensibility, the agility of Open Source database software gives you the ability to let your database, be it OLTP, OLAP, Big Data, Polyglot, or whatever we come up with, do what needs to be done.
The current leader of the Open Source relational database systems is PostgreSQL. A platform developed in over 30 years to become an absolutely stable data processing engine for a fraction of the costs of the Closed Source players in this market.
- We have seen wave 1 of Open Source where we all choose to replace the operating system standard with Linux.
- We will now see wave 2 of Open Source where we will choose to replace the database management system standard with… PostgreSQL (or in specific cases one of the other, more specialized systems, depending on the need).
