Teams and MDBs
For ease of working DBs are grouped into Teams and MDBs (Multiple Databases). A DB belongs to one team, but may be in many MDBs. You must specify the MDB to work on when entering AVEVA E3D™.
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 the
