This may be managed directly on an individual basis, or by the assignment of individuals and privileges to groups, or (in the most elaborate models) through the assignment of individuals and groups to roles which are then granted entitlements. Data security prevents unauthorized users from viewing or updating the database. Using passwords, users are allowed access to the entire database or subsets of it called "subschemas". For example, an employee database can contain all the data about an individual employee, but one group of users may be authorized to view only payroll data, while others are allowed access to only work history and medical data. If the DBMS provides a way to interactively enter and update the database, as well as interrogate it, this capability allows for managing personal databases.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is a subset of a database called that can be accessed by using a password?
Ah, so.. subschemas

The southern group (South Estonian language) consists of the Tartu, Mulgi, Voru (Voro) and Setu (Seto) dialects. These are sometimes considered either variants of a South Estonian language, or separate languages altogether. Also, Seto and Voro distinguish themselves from each other less by language and more by their culture and their respective Christian confession.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What dialects comprise the southern group?
Ah, so.. the Tartu, Mulgi, Voru (Voro) and Setu (Seto) dialects
