I have used MySql and SQL Server for some time. Not for something that complicated! Mainly for web and desktop database integration.

I have also used SQLite for many simple programs (not just a RDBMS, I understand!). I've not used Oracle even once.

The truth is I wish to start learning a RDBMS completely and that i really do not know which to choose.

I understand that for instance if you realise MySql completely, you will not enter into much trouble dealing with other RDBMSes available. The truth is I haven't any understanding of extra and exclusive features every one of them offer. I'm not sure which is much better that atmosphere and honestly I'm not sure the way they differ form one another! :(

I needed to consider a training course on Oracle however I stated "Hey wait! Let's say there is a more sensible choiceInch.

I'm a large fan of .Internet i enter in Java and PHP.

I am really confused and that i really should get began early. Any assistance is totally appreciated.

Edit 1: Can anybody let me know about how exactly much data each one of these are designed for? I am talking about I understand that for instance Oracle are designed for great deal of data! I would like a kind of comparision: for instance Oracle > SQL Server > MySql... Also I must know which is more potent within the facet of features.

Edit 2: I truly don't understand how to thanks all for the reactions! I am totally astonished by the precision and simplicity individuals reactions!

For anyone else who might run into this: I have decided and I am choosing SQL Server due to it is good balance in features and availability and simplicity! The ANSI SQL and it is features insInternet (like Linq to Sql) are large advantages for me personally! At some point I would use PostgreSql however i don't believe I am going anywhere near Oracle! A minimum of for the moment! :D

Again thanks all

I wouldn't jump into Oracle at this time, if you have never done it and do not use whatever immediate have to.

Both MySQL and MSSQL are broadly available and used (specially the Express models of MSSQL) and therefore are excellent options for many projects. You'd prosper to understand each one.

Beyond that, I recommend that you simply learn no matter which the first is that appears to be installed where you will need to be utilising it. Like a general rule, that's MySQL in Linux/UNIX and MSSQL on Home windows.

Anything further than that's engaging in summary territory.

Learn MySQL if you prefer a "popular" and free database. It isn't probably the most advanced, but it is very broadly used.

Learn PostgreSQL if you would like the (most likely) innovative free database.

Learn Oracle if you would like the heavyweight database that's used a great deal within the enterprise.

Learn SQL server knowing you will be a great deal in Microsoft space.

Note: above choices are my very own and therefore are clearly subjective. As always, there's no "definite" answer.

Study several: Oracle, SQL Server and MySQL are great set to understand because they are most likely probably the most broadly used - a minimum of in web database integration.

SQL Server may be the simplest to obtain on Home windows and it has the very best tools. MySQL is really a close second on Home windows. MySQL's GUI on Linux last I checked was just so-so. In case your confident with an order line interface on Linux then MySQL is what you want.

That noted, so what can help drive your final decision is programming language.

Many of the notable because SQL Server and Oracle execute code in individuals particular languages (have no idea what choices are there for MySQL).

Also, you will find other interesting facets of every database, for example MySQL causes it to be particularly simple and easy , cheap to setup master-slave replication, SQL Server has some very helpful confirming tools built-in, Oracle does is most likely probably the most stable from the lot pressurized - but you need to know how you can tune it much better than the relaxation in my opinion.
