Data is nothing but a collection of information. The information itself is unimportant. What is important is how that information will be used. The way information is used is the predicate for its organization.
After you grok that then you can start to learn how electronic systems store and retrieve information.
One of the things that has never let me down is the fundamental understanding of how computers work. Remember that no matter what whiz bang shite you read about, computers do exactly two things: They loop and they branch nothing more nothing less.
Once you have that in your head, then you can begin to think about how the results of your analysis of the uses of the data can best be organized to make the job of the machine smaller and faster.
None of this is intuitive. It is all based on understanding gained from reading books of theory and the practical application of those theories and by trial and error. Every data use case will present its own challenges, but if you want to do serious database work never ever let a coder dictate the data schema. Never let them short cut and make your data organization match the organization of the data structures in their code because 99 times out of 99 times they have organized their data structures to suite their coding style and 99 times out of 99 times it will be completely hair brained and not have any relevance to the best way to store and retrieve some data from the mountain of data you need to store.
The reason aircraft engines are built so very simply is for reliability. Everything you add is just another thing to malfunction. When you are 1500' in the air, over a city, you have pretty much no wiggle room. Find someplace to land now! At 1500' you have less than a minute to get it figured out and and around 1 more minute to get the thing on the ground.
MANY people have tried to adapt car engines to GA aircraft only to see them fail, time and time again. Cooling problems, vibration problems, fuel problems, you name it.
Diesel engine technology is being heavily tested and one or two have even entered production, but those have a very long way to go before they can be said to be reliable. And that is reliable to a standard that everyone can basically bet their life on, not just the pilots, not just the passengers, but people just like you, living your life peacefully until that airplane comes through your roof.
For any airplane to fly it is always the weight -v- lift -v- drag -v- power trade off.
I would love to adapt a Ferrari flat 12 for aircraft use. It runs on unleaded, meets California smog rules, you can get LOTS of horsepower out of 5 liters ( 12 cylinders ). Basically you get 480hp and 480 foot pounds of torque at about 6800 rpm and when you reduce that to 2400 rpm or so you 480 foot pounds * ( 6800 / 2400 ) and you can go really fast.
Actually I would have to say it went off the rails at 1.4. Prior to this it was a language that fulfilled a laudable goal. After that it was just down hill and that course has not changed. It is the classic too many ornaments on the tree condition.
Java as a language for the web is utterly laughable as evidenced by the massively bloated applications that are Tomcat and Glassfish, Weblogic and the rest.
But the ultimate insult is the world wide web. Stateless, anonymous and ultimately hideous to try and accomplish anything of substance. While some might disagree, they have only to look at web sites with very large java back ends to notice how lethargic they were are and continue to be.
I know everyone love to shit all over Oracle, but you cannot lay all the problems with Java at their feet and to try and do so makes you look rather, well, for lack of a better word, foolish. The problems existed long before Oracle acquired Sun.
Java is a god awful mess of a programming language to use. This just might kill it. I mean as much as a hate python ( it is a personal taste thing, not a reflection on the utility of the language ) I hate java even more.
If Gosling had spent as much time developing a great C libraries as he did the POS that is Java we would all be writing in the native language of Linux.
98% of "web Programmers" wouldn't know a good database if it dragged them out of the parents basement and gave them a blow job.
I would not recommend using Oracle to run a simple web site. It is complete over kill. I would not recommend using MySQL / Maria to run the VISA processing center either.
99.9% of application builders do not even know the value of a good, much less great, DB engine and that is proven out time and time again when you look at their DB schema and all you see are tables. They all insist on doing EVERYTHING on the front end and never get , even when advised about, the amount of power that DB's like Oracle, PostGres, MS-SQL, DB2 and even MySQL have these days. One well written Stored Procedure ( Oracle Speak ). Package ( Oracle Speak ), function ( PostGres Speak ) or Procedure ( MySQL/ MS-SQL Speak ) can eliminate 1000's of lines of java, python, ruby, php ( pick your language ) front end code, and perform the function 1000x faster and more reliably.
Every tool has its use. When you need massive scaleibility, up time in the 5 9's category and support RIGHT FUCKING NOW WITH AN ACTUAL ENGINEER when you dial the toll free number 24/7/365 you get the big dogs like Oracle,MS-SQL or DB2. If those factors are less important then you have other choices like Postgres ( they REALLY need to fix the TXID issue ) which is very powerful but lacks the kind of SLA's that you can get with Oracle / Microsoft. If just getting feedback from the support community is fine the MySQL / Maria are fine choices.
I design VERY large databases that push DB's to their limits. Google had to design their own because nothing off the shelf or even from the FOOS community could handle their requirements but it takes a small army to deal with it and most companies don't have the resources or don't want to have that many people on their payroll.
The bottom line is use the DB that fits your requirements, fits your budget and has the support organization around it so when you have a problem your requirements are met, and it really does not matter who you get it from. Don't be religious about it. ALL of these companies are trying to build the best product to serve their market and that is the bottom line.
Michael Widenius is nothing but a little bitch. He sold his DB to sun for how much again? 1 BILLION dollars I think it was. Now shut the fuck up, go sit on your riches and do MariaDB if you want but stop bitching about what happened to MySQL because he YOU are the idiot who cashed in and sold out.
You wont get any serious replies. Remember this is/. and the vast majority of the people here are haters on anything they can't just take, no matter how much work was put into it, by whom. And they especially hate Oracle for having the nerve to try and make money.
Simply use three sensors and a prism. The color separation camera has been around for along time and the color prints from it are just breath taking. Just use three really great sensors then we can have digital color that rivals film.
Check out the work of Harry Warnecke and you will see what I mean.
What you are talking about is called Exposure Latitude of which dynamic range is a component. Digital has quite a way to go before it catches up with color negative film.
So while my answer might seem quite pessimistic, I think, and sadly, it is true because much like Communism it works fine on paper but almost never in practice and happily Valve has found one of those rare exceptions in time when it does.
In an often debated subject of military acquisition disasters Boeing won't do anything unless there is a check in it for them. This is a sour grapes in many ways since Boeing lost out on the contract for the F35, but Boeing hasn't forgotten what happened to Northrop with the http://en.wikipedia.org/wiki/Northrop_F-20_Tigershark#FX_stumbles_and_F-20_emerges program.
I'm sorry but when an entire program can be broken by simply using a different editor with slightly different tab settings, then that language AND its designer deserve all the derision and scorn that could possibly be heaped upon it.
You have obviously never been on a submarine under construction. Guess what, I have, SSN-692, and that was quite a few hulls later after the SSN-688 ( the first of the class ) was first built. The mini-grinder is the tool that every mechanic takes with them. Piping gets pulled into place with a chain fall so it can be welded in, hammers are used to bend shit into the right shape. let me tell you, General Dynamics has ALL the cool toys for this shit.
You want to talk modern? The latest combat ships are built up module by module and let me tell you those designers have the coolest toys and yet they still need big mofo's with big hammers to get things to line up and still still does not fit like it should.
You have a really fucked up attitude for someone with such a low id number. The person you replied to had valid points and you come off like some shitbird who does not have a fucking clue.
You are both correct and incorrect. I have a couple of friends who are architects. The reuse major structural elements, design elements etc.. They also come up with new stuff, so yes and no.

Calling out a bug for comparing a quoted string to null, eg: '1234mhgt' = null tripping up the optimizer?
No wonder Oracle is ignoring their asses. I would too!

Yeah I noticed that right AFTER I hit submit. Yet another /. non-feature, even though I do understand why.
Please show your work eg: int foo(int x,y){ return x+y};
