I'm not sure what the question is asking so I'll just describe a database.
1.  A database must have information in it.
2.  The information must have meaning. Random data without meaning cannot make
    up a database.
3.  The information in a database is put there for a specific purpose. It has
    an intended group of users and an application that the users are interested

I really don't understand what the question means when it says "main types of
  actions". I would assume the following actions:
- input, update, delete information.
Input is inserting information in to the database.
Update is changing any present information in the database.
Delete is removing any present information from the database.
