Types of Users:
1. Naive Users: These users have limited technical knowledge and primarily interact with the database
through simple interfaces like web applications or reports.
2. Sophisticated Users: This category includes users who have a deeper understanding of database concepts
and can write complex queries or use specialized tools.
3. Application Programmers: These users develop applications that interact with the database. They write
code to access and manipulate data.
Key Responsibilities:
- Data Retrieval: Querying the database to extract relevant information.
- Data Modification: Updating existing data or inserting new records.
- Data Analysis: Using database tools to analyze and interpret data.
- Application Development: (For application programmers) Creating software that interacts with the database.
Database Administrators (DBAs)
Definition: DBAs are responsible for the overall management and maintenance of a database system. They

Key Responsibilities:
- Planning and Design: Defining the database structure, schema, and data models.
- Implementation: Installing and configuring the database management system (DBMS).

- Performance Tuning: Optimizing the database for efficient performance.
- Backup and Recovery: Creating regular backups and developing recovery procedures.
- Capacity Planning: Ensuring that the database has sufficient resources to handle future growth.
- Troubleshooting: Identifying and resolving database issues.
Relationship Between Users and DBAs
Collaboration: DBAs work closely with users to understand their requirements and ensure that the database
meets their needs.
Access Control: DBAs grant appropriate access privileges to users based on their roles and responsibilities.
Support: DBAs provide technical support to users when they encounter problems or have questions.
