MS SQL backend

MS SQL backend

We have been using ELA for a long time and we use a MS SQL backend for the database. I have a couple questions around this.

1. What all is the database holding? This is curiosity question.

2. Is there any regular maintenance that needs to be done on the ELA database? We have been running this for years and mostly without any issues but it has occurred to me that we never do any maintenance on the database itself and I cant find any documentation on it either.

Thanks
