AVEVA E3D™ Databases : Database Access
Database Access
This section introduces the basic database access mechanism. For information about more extensive Data Access Control, refer to Data Access Control (DAC).
Database access depends on attributes of the User and of the Database.
Users can be FREE or GENERAL:
FREE Users
May enter all modules.
May update any databases.
GENERAL Users
May not enter the Restricted modules; usually the administration modules ADMIN and LEXICON.
May only modify databases for teams of which they are members.
Note:
User privileges also control access to modules; refer to Modules.
Databases can be UPDATE or MULTIWRITE:
UPDATE
Allow one writer and n readers.
MULTIWRITE
Allow m writers and n readers. Refer to Multiwrite Databases and Extracts for further information about multiwrite databases.
MODEL, CATALOGUE, DRAFT (PADD) and ISODRAFT databases can be multiwrite. The SYSTEM database is always multiwrite.
Both UPDATE and MULTIWRITE databases can also be CONTROLLED, in which case write access is controlled externally to AVEVA E3D™. Refer to CONTROLLED Databases.
•
You can change an update database to multiwrite at any time.
•
You can only change a multiwrite database to update if no extracts have been created from it. Refer to Extracts for further information about extracts.
