For ease of working DBs are grouped into Teams and Multiple Databases (MDBs). A Database (DB) belongs to one team, but may be in many MDBs. You must specify the MDB to work on when entering AVEVA E3D Design.
Details of DBs, teams, and MDBs are stored in the system database.
An example is shown below.

It can be seen that DB /A is only in MDB /X, whereas DB /B is in both MDB /X and /Y.
Team access controls fundamental write access. Members of Team1 will always have write access to DBs /A and /B, and read access to the remainder. For members of Team2 it will be the opposite way around.
If a DB is included from another project then it is always read only regardless of team membership.
These concepts are discussed in detail in Administrator User.
