There are following types of users: § Database Administrators § Security Officers § Network Administrators § Application Developers § Application Administrators § Database Users
The types of database supported by PostgreSQL are Boolean, numerics, binary, composite, arrays, and date/time stamps. Another option is that users can create their own database types using this software.
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 database management system is a collection of programs that enables users to create and maintain a database. The DBMS is general purpose software that facilitates the processes of Defining, Constructing, Manipulating and Sharing data among various users and applications.Defining a database involves specifying the data type, structure, and constraints of the data to be stored in the database. The database definition or descriptive data information is also stored in the database in the form of a database catalog or dictionary; it is called meta-data.Constructing the database is the process of storing the data on some storage medium that is controlled by the DBMS.Manipulating a database includes functions such as querying the database to retrieve specific data, updating the database to reflect changes in the miniworld, and generating reports from the data.Sharing a database allows multiple users and programs to access the database simultaneously.

Database comes from the end user or the database users. Combining all the data database system is formed.
Defining a database involves specifying the data types, structures, and constraints for the data to be stored in the database. Constructing the database is the process of storing the data itself on some storage medium that is controlled by the DBMS. Manipulating a database includes such functions as querying the database to retrieve specific data, updating the database to reflect changes in the miniworld, and generating reports from the data. Sharing a database allows multiple users and programs to access the database concurrently.
