fkchk is a MySQL InnoDB/XtraDB foreign key checker and repairer. It is useful if you suspect that your database's foreign keys may be broken, or if you disable foreign key checks and now want to be sure that the data is consistent. It is also useful if you have suffered a performance hit and want to check the consistency of foreign keys to verify that they're not the reason. It can attempt to repair any issues it finds, but this option should not be used and is only implemented for testing purposes.
openDCIM is a Web-based data center inventory application which allows you to manage capacity and track assets throughout multiple data centers. There are some graphical elements to the system, but overall, the system is designed for keyboard-friendly (rather than click-happy) use. It is written in PHP and utilizes a MySQL backend for ease of deployment on nearly any LAMP-based build.
Mysql Done Right is a PHP 5.0+ class that provides a safe, clean, object-oriented, and efficient way to do database development. All queries except those with multiple row results return exactly what you need in one line of code. This is all done while still maintaining use of prepared queries and bound parameters to eliminate the risk of SQL injection attacks and operate more efficiently. No extra coding is needed on your part to reuse prepared queries. You simply write the same query again, and if you have used that one before, the prepared handle is reused. The newly bound parameters are used against the existing prepared handle, and the results are recomputed. The results themselves are not cached. Database connectivity is implemented using MySQLi.
