Run

The database is equipped with the following scripts, located in the script folder:

• create.py: creates the database and fills it with testing data
  • -s flag skips the insert phase
• drop.py: drops the entire database
• insert.py: clears and re-inserts testing data into the database
  • -s flag skips the clear phase

Development

• If you want to make changes, please test them in the development database
  • To do so, simply change the DB_NAME in the .env file to the dev database name

Run these scripts with a command such as python3 script/create.py.

The database diagram can be found here: full, readonly.

When the diagram is updated, just export it into MySql and copy the contents into manage/create.sql and update the inserting scripts to go with your changes.

Insert Priority Graph

This graphs shows what table is required in witch table.

By traversing the graph from source to most distant node, we can determine the order in which the tables should be inserted. Dashed lines represents a split creation due to cyclic dependencies.
