Users are distinguished by the way they expect to interrelate with the system.
- Application programmers – interrelate with system all the way through DML calls
- Sophisticated users – form requests in a database query language
- Specialized users – write dedicated database applications that do not fit into the traditional data processing framework
- Naive users – appeal to one of the permanent application programs that have been written formerly
Examples, people accessing database in excess of the web, bank tellers, clerical staff
