Just another example of a bad reply and the real value of professional certification

September 28, 2012 Leave a comment

I don’t like forum or chat-like flame wars of any sort. As a matter of fact I feel disgusted by towards those people participating in this kind of activity. Besides, there are no real “winners” and “losers” in this kind of activity – both parties prove themselves to be morons.  But sometimes… Here is the good example. It’s not really a flame war, just looks like one. And one side is totally right. Here I’m completely on Tara Kizer’s side.

Please, do not be like that guy. Neither in participating in forums nor in life, as much as you can. Bad example indeed. And hey, here is “…MCP, MCTS” Another prove of what all that so called “professional certification” worth. Such a scam…

To switch or not to switch? And if to switch then what, a hardware platform or Database? And if to go with the second choice then should it be some “rare” one, to have more “fun”? Oh, no, rather not…

Continuing the series of interesting points of view on RDBMS-related topics.

Argument about Oracle announcing desupport of HP-UX (Itanium) by Fernando Nunes

And my comment on that:

–===================================================================–

Interesting point. Can’t agree on the conclusion for, mainly, two reasons, though.

For one, hardware upgrades are not that “big of a deal” – it has to be done every once in a few years anyway, so there’s nothing wrong with switching from HP-UX on Itanium to Unix(Solaris)/Linux on whatever other platform; there are plenty.

For two, – resources. “Sad but true” – there is a kvazillion resources which come up for SQL Server and Oracle from just googling practically anything in regards to either of these RDBMSs, and… almost none for Informix. It seems like the product’s been completely abandoned or, otherwise, left behind very profoundly. Well, apparently it is quite a story to get  free  ODBC Informix drivers for Windows 7 64-bit – there are simply none out there. There are some third-party ones, but that’s another story. You would think there must be any RDBMS-provider ones. Or if there still are, then why is it such an arduous task to find any?

Too bad ’cause even from reading bits and pieces of info I managed to find about Informix, it seems like some really good db, with great performance among other advantages.

As both Oracle and later SQL Server DBA – never came across Informix before in 10 years of my experience anywhere, i.e. lots of Oracle, lots of SQL Server, quite a few MySQLs, some DB2 here but… no Informix. So, if the popularity and widespread is not there, who would want to switch to Informix rather than switch just to other hardware, which will have to be upgraded (read changed) anyway? On my strong opinion, Informix, as for now goes exclusively as upgrade for any existing projects, any IBM products db backend or any new projects which are run by people who come from Informix side. Can’t really think of anyone planning to migrate to Informix all over a sudden, especially from such main players as Oracle and SQL Server.

There is also a third reason. It’s very much subjective yet seems pretty accurate as soon as many agree on that: IBM support is probably the worst and most definitely one of the worst out there. Dealing with IBM is totally pain in the neck. Even judging by my personal experience with Cognos – before IBM bought it, Cognos Support was awesome, now it’s as bad as it can get. IBM for many and many years has been consistently proving itself as highly bureaucratic, awkward and sluggish company. Ending up with IBM being the major, and kind of a single capable resource out there to address any Informix issues, is the factor to reject the very thought of going with Informix, no matter how great RDBMS it is.

Interesting view on non-relational database management systems alternatives

Is the Relational Database Doomed? by Tony Bain

As a matter of fact, up untill probably couple of weeks ago I N-E-V-E-R heard anything about non-relational database management systems. Not that it’s automatically supposed to mean they never existed, – obviously not, but  definitely implies there are far, far not that popular as RDBMS. 

This notion of non-relational DBMS alternatives a bit kicked me to the head and made me decide to write this short critical post.

At first, I must admit, the author does make his point, but to a very small degree. There are quite a number of serious flows in his argument, making it totaly weak.

It starts with the most minor one right at the very beginning    😉 But that’s nothing really, of course. “Fixing” it just for fun:

–Civic is Honda
UPDATE MakeModel
SET MakeKey = 1
WHERE MakeKey = (SELECT MakeKey FROM Make WHERE Make = ‘Nissan’)
AND Model = ‘Bluebird’;

Then the author mentions that 

“new” type of database has been around for a long time and has been used for specialized applications for which the generic relational database was ill-suited

without giving a single example… Not a cool thing to do, especially attempting to question such a serious matter as  prevalence of relational DBMS over any other database systems and, what’s more to it, putting the entire future of RDBMS to a subject. One would expect some really kind of a bullet-proof, very obvious, no-flaws argument in this.

Then comes something weird. Well, I’ve modified it a bit – the way it supposed to be.

The data model is based on business requirements. Application functionality is supposed to reflect the very same business requirements and follow the data model, if this is relevant to mention at all. This entire thing doesn’t make any sense. The next one, about data model being normalized is true only for some systems, called “Operational” or OLTP in the older notation but not Data Warehouse ones. Data Warehouse systems has data de-normalization as its very base principle. And further on in his article, the author keeps building his argument like Data Warehouses never existed in relational database world – WTF?!?!

 The rest of his argument goes nowhere really. Such features as parallel execution, partitioning and data compression, which make up great performance improvements in relational databases, have never been mentioned in the article. At the bottom line, his point is this: “if you want to go with WebServices, choose key/value non-relational DB”. Well, cool, dude. Do it if you dare, – it’s “your” money at the end of a day. Well, not really yours, but the corporate ones. It’s all the question of a what you’re willing to risk.

All in all, the time and the market will show whether those “key/value” barely known around database systems have their potential or not. Meanwhile, relational databases will be there as the one and the only main player for a lifetime of computers operating on the basis of zeroes and ones.

Not anyhow database-related; simply couldn’t resist re-posting.

Sad, but so true…
