7. Share data:
Database systems provide significant sharing with multiple system users.
8. Easy maintenance:
Since the applications deal with the same database, any modification is made in one
place in the database easily and conveniently and under the responsibility of the
specialist (for example, when modifying the number of course hours, the modification
is made directly to the schedules of professors and students).
9. Data independence:
Designing the database is done separately from the applications that use it. that
grantees that any maintaining of these applications or even developing new
applications done away from the database and does not affect it. Furthermore, the
database can be on a server device and any application runs on other devices so that
if these applications malfunction, the database will not be affected by that.
10. Data security and confidentiality is very high:
Database systems include giving specific permissions to each group of users, and this
highly secures the data against unauthorized users.
