When you
access a CA-Datacom/DB database, you can work in either a single user execution
environment or a multi-user execution environment. In a single user
environment, each user has a copy of CA-Datacom/DB and has exclusive
use of the database.
The SAS/ACCESS interface
to CA-Datacom/DB runs only under a multi-user environment. In
a multi-user environment, many databases can be accessed from many regions
concurrently, with exclusive control at the logical record level. Only one
copy of CA-Datacom/DB is required to handle all regions. Recovery is centralized
for all users.
