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.

There are generally three main types of database system users: database administrators (DBAs), who manage and maintain the database; application developers, who create applications that interact with the database; and end-users, who utilize the applications to access and manipulate data. Each user group has distinct roles and responsibilities, contributing to the overall functionality and management of the database system.

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.
The three building blocks of a database are data, database management system (DBMS), and users. Data refers to the information stored within the database, organized in a structured manner. The DBMS is the software that facilitates the creation, manipulation, and administration of the database, allowing users to interact with the data effectively. Users are individuals or applications that access and utilize the database for various purposes, such as data retrieval and analysis.
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
