Types of Database users

Types of Database Users:

1. Database Administrator (DBA):

• DBA Stands for ​Database Administrator​.
• It is a person or a team, who is responsible for managing the overall database management system.
• It is the leader of the database. It is like a superuser of the system.
• It is responsible for the administration of all the three levels of the database.
• DBA is responsible for:
• Deciding the instances for the database.
• Defining the Schema
• Liaising with Users
• Define Security
• Back-up and Recovery
• Monitoring the performance

2. Database Designers:

• Database designers design the appropriate structure for the database, where we share data.

3. System Analyst:

• System analyst analyses the requirements of end-users, especially naïve and parametric end users.

4. Application Programmers:

• Application programmers are computer professionals, who write application programs.
• They are the developers who interact with the database by means of DML queries. 
• These DML queries are written in the application programs like C, C++, JAVA, Pascal, etc.
• These queries are converted into object code to communicate with the database. 
• For example, writing a C program to generate the report of employees who are working in particular department will involve a query to fetch the data from database. It will include an embedded SQL query in the C Program.

5. Naïve Users / Parametric Users:

• Naïve Users are Un-sophisticated users, which has no knowledge of the database. 
• These users are like a layman, which has a little bit of knowledge of the database.
• Naive Users are just to work on developed applications and get the desired result.
• For Example, the Railway’s ticket booking users are naive users. Or Clerical staff in any bank is a naïve user because they don’t have any DBMS knowledge but they still use the database and perform their given task.

6. Sophisticated Users:

• Sophisticated users can be engineers, scientists, business analysts, who are familiar with the database. 
• These users interact with the database but they do not write programs. 
• They are database developers, who write SQL queries to select/insert/delete/update data. 
• They do not use any application or programs to request the database. 
• They directly interact with the database by means of query language like SQL. 
• In short, we can say this category includes designers and developers of DBMS and SQL.

7. Casual Users / Temporary Users:

• These types of users communicate with the database for a little period of time.
