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.

Assignment

Assignment table represents exercise assignment in a group. It holds keys of the exercise and group where is the exercise assigned. Other columns are:

isPublic -- assignment can be public (visible to students) or private (visible only to supervisor of the group)
submissionCountLimit -- number of attempts student can make to solve the exercise
scoreConfig -- configuration for calculating point score; actual syntax depends on used score calculator
firstDeadline -- date and time after that no new submissions are received
allowSecondDeadline, secondDeadline -- flag if another deadline is allowed, date and time of that deadline
maxPointsBeforeFirstDeadline, maxPointsBeforeSecondDedline -- maximal amount of points for correct solutions for first (respectively second) deadline
scoreCalculator -- name of used score score calculator or NULL for API's default one
canViewLimitRatios -- flag if student can view percentage of used time and memory limits for each test
deletedAt -- assignment cannot be deleted due to possible numerous dependencies, but can be hidden from the users; published assignments have NULL value, deleted ones have time of deletion
