sequence
With the growing Internet development and free software software, more and more people began to apply various databases in their own network applications. As a result, various database systems appear on the internet stage, the most commonly used databases here are mysql and postgreSQL, which has different applications and user groups in the Internet. Interestingly, like the controversy between FreeBSD and Linux inside the operating system field, there is a small argument between these two databases, and these debates have greatly affected the user's own Judgment, it also feels uncomfortable when the user will choose, in order to facilitate everyone to use their own eyes, we specially organize comparison information provided by all aspects, focusing, for everyone to use. At the same time, the materials we collected have some information about other databases, in order to provide you with more complete information as much as possible, we also included them. Here we mainly conduct features and performance comparisons, there are other important factors, such as copyright and active, etc., can be easier to get in our other resource parts, this is no longer repeated.

PostgreSQL test
Postgresql's own comparison test is relatively simple, mainly based on characteristic comparisons, but it is interesting to have no mysql's figure in this list. From PostgreSQL concept, mysql is not a complete database, probably because of current mysql There is still lack some key database features.
Here is a simple contrast of PostgreSQL yourself.
Mysql test
MySQL provides a database test kit and is the most abundant and detailed data in the materials we collected. In addition to providing comparison with PostgreSQL, it also provides comparison data with many other databases. The comparison of mysql is based primarily based on speed and performance, and there is a characteristic comparison between all of its participation platform, but lack of RDBMS-InterBase that is becoming free software (Interbase is open from 6.0, but I don't know if GPL) .
The following is the acquired information and test results on the MySQL site:
You can find the full source code of the test program from the MySQL source release version and some contrast data sheets.
The entry for _fast tags is to be tested using the cleaning command (Cleanup calls) in non-standard ANSI SQL mode. This is no longer a hundred percent SQL, but these data items are still very useful.
Some entries are sent to us by anonymous MySQL users, so they cannot guarantee that these test data are fully accurate, we recommend running this test program on your own database. If you are willing to share your test results with us, you can upload the files in the 'Output' directory to 'www.tcx.se/pub/mysql/incoming' so that we can be in the future test results. Publish these test data.

TCX declaration information:
This information is provided by TCX, so the user can get the real situation of different databases (not information provided by the vendor). I hope that the above information will make you easily find the features you need and you have such a database server that can be used with confidence.
We will continue to work hard to help users understand the running speed of the database when doing different typical work.
TCX also continues to develop Crash-ME to show the real defects and performance of the database server.
Other resources
There are also some comparisons of voting nature in www.linux.com and www.linuxcare.com, these mainly user personal preferences and views, no clear test standards and means, but there must be a certain reference value for everyone, we are Link here, please visit these links to see the voting results.
