| 15 | AristotlePagaltzis | 1 | [MySQL | http://www.mysql.com/] is a PostRelationalDataBase management system. It is the canonical example of a successful commercial OpenSource product. This has been attributed primarily to the fact that it's DualLicensed. |

| 3 | Some also say it is devil spawn or a horrible piece of badly written software. It's very fast at low loads because it's hardly more than a glorified flat file database with an [SQL] interface, but that comes at the expense of any feature anyone would find useful (transactions, as one example). It sucks at large joins and has trouble handling tables with a few million rows in them. | ||

| 5 | If you want a relational DataBase, use [PostgreSQL]. You'll love yourself forever if you do. | ||

| 17 | AristotlePagaltzis | 12 | > For a large portion of the new markets being created by [MySQL], this advantage ''~[easy to install while reasonably useful, Ed.]'' matters a lot more than missing features and poor [ACID] semantics. If this shocks you, then remember that [MySQL] is used for the InterNet-enabled version of what people used to use MicrosoftAccess for. Compare [MySQL] to Access on technical grounds -- who wins? |

| 21 | __GATES__: ''Nobody'' expects the [InfoWorld Article | http://infoworld.com/articles/pl/xml/02/09/23/020923pldman.xml]! The chief thing missing from [MySQL] is subselects...subselects and views...views and subselects.... The two things missing are views and subselects...and triggers.... The ''three'' things missing are views, subselects and triggers...and an almost fanatical devotion to row-level transactions.... The ''four''... no... ''Amongst'' the things missing from MySQL ...are such elements as views, subselects.... I'll come in again. | ||

| 27 | <br> __When should I use [MySQL]?__ : | ||
| 28 | When your primary concern is the speed of simple <tt>SELECT</tt> queries for few concurrent users. Even then [PostgreSQL] is getting much quicker at these. | ||
| 29 | <br> __When should I not use [MySQL]?__ : | ||
| 30 | When you think "It's only going to ever be a small web site...", and there's a chance it could grow into a big one. If at any point you think you might need to change to something else, start with that other system instead. | ||
| 31 | <br> __How can I lessen the impact of having to switch later on?__ : | ||
| 32 | Use PearDB in your [PHP] scripts, or DBI in your [Perl] scripts. | ||
