+# DBM service
+
+## Description
+
+This service is used for our database monitoring courses, built with Python that uses the SQLAlchemy ORM to connect to a Postgres database. When the service is started, the library Faker is used to generate fake data for the database and in our labs we run a few queries in the background to simulate a load on the database.
+
+> TODO: Add queries from labs to this repo
+
+There is also a user-facing component to this service, which can be seen in the `frontend` service with a specific flag thrown in the `featureFlags.config.json` file. Turning it on will result in a product ticker being displayed in the navbar of the application.
+
+## Database schema

+The database schema can be found in the `models.py` file with these models:
