There are following types of users: § Database Administrators § Security Officers § Network Administrators § Application Developers § Application Administrators § Database Users
they are people who interact with a database system in different ways and they are as follow 1- end users 2-database designers 3- database administrators 4- application programmers
Database comes from the end user or the database users. Combining all the data database system is formed.

DBA users, or Database Administrator users, have elevated privileges that allow them to manage and maintain the database system, including tasks like creating users, managing security, and performing backups. In contrast, all users encompass anyone with access to the database, which may include standard users with limited permissions to read or modify data but without the administrative capabilities of DBA users. Essentially, DBA users have comprehensive control over the database, while all users have varying levels of access based on their assigned roles.
In a database management system (DBMS), specialized users are individuals with specific roles or expertise related to database administration, development, or analysis. These users typically have advanced knowledge of the DBMS platform and are responsible for tasks such as database design, optimization, security implementation, and performance tuning. Specialized users often contribute to improving the efficiency and effectiveness of database operations within an organization.
Database auditing involves observing a database so as to be aware of the actions of database users. Database administrators and consultants often set up auditing for security purposes.
4 Types of Database Users Users are differentiated by the way they expect to interact with the system: · Application programmers - interact with system through DML calls. · Sophisticated users - form requests in a database query language. · Specialized users - write specialized database applications that do not fit into the traditional data processing framework. · Naive users - invoke one of the permanent application programs that have been written previously.FROM: Database Systems Concepts 1.17 Silberschatz, Korth and Sudarshan c1997
A centralised database is a single database under the control of a single Database Management System. All users and client applications connect directly to the DBMS. This means that the database is stored in only one location and everyone in the system is directly connected to it. Unlike a distributeddatabase which is a set of connected databases stored on multiple computers that appears to users as a single database.
A database management system (DBMS) is responsible for providing users with access to appropriate data in a database. The DBMS controls user access permissions, enforces security measures, and manages queries to ensure users can retrieve the data they are authorized to access.
