When you access a SYSTEM 2000
database, you can work in either a single-user or a
Multi-User execution
environment.
In a
single-user environment, you are working with your own copy of SYSTEM 2000 software. You usually have exclusive
access to the database. However, the single-user environment can be configured so
that all users can query
the database.
In
a Multi-User environment, many users can access a database at the same time, with queries and
updates being handled simultaneously by the Multi-User software for all databases being accessed. The Multi-User
environment automatically ensures data protection during concurrent
updates, and it automatically guards a database against conflicting
tasks.
