# Database
|
|
|
|
Used database schema is generated by ORM framework Doctrine from ReCodEx API source code. Tables are directly mapped to _entities_, which are PHP classes annotated with data provided by ORM framework. In the following text there is a brief description of each such entity. There may be some additional database tables for many-to-many relations between entities, but these tables are not discussed in detail because there are only two columns with keys of both related tables in each one. Graphical database schema is added as attachement to this documentation.

|
|
- _scoreConfig_ -- configuration for calculating point score; actual syntax depends on used score calculator

|
|

|
|
- _canViewLimitRatios_ -- flag if student can view percentage of used time and memory limits for each test
