Management console all repositories

Currently i am monitoring running jobs from management console(MC) , and i wanted to monitor from database as well for all repositories.

I know every repository has its own schema and tables for running job logs.

first i wonder is there any table that holds that information of repositories' list ? Then i can create a query for monitor for all repositories at once.

lets say i have 2 repositories named like repo1 and repo2.

so my query would be something like this :

select * from repo1.al_history

union all

select * from repo2.al_history

secondly i just wonder is there any other schemas(for querying MC interface) other than repository schemas that holds meta data ?

Thank you.
