There are several types of database users, each with their own specific needs and access levels. Some common types of database users include: -
Database Administrators - These are individuals responsible for managing and maintaining the database system. They typically have the highest level of access and control over the database and are responsible for ensuring its security, performance, and reliability.
Application Programmers - These users are responsible for designing and developing software applications that interact with the database. They may create custom queries or programs to retrieve, manipulate, or update data stored in the database.
End-users - These are individuals who use the database to access, view, and modify data for their specific needs. They may include employees, customers, or other stakeholders who need access to the database for business operations.
Data Analysts - These users are responsible for analyzing and interpreting data stored in the database. They may use tools like data mining, statistical analysis, or machine learning algorithms to extract insights and identify trends from the data.
Executive Users - These users are typically high-level managers or executives who need access to the database to make informed decisions based on data-driven insights.
External Users - These users are individuals or entities outside of the organization who need access to the database for various reasons. Examples may include suppliers, partners, or customers who need to access data related to their interactions with the organization.
The access levels and privileges of each type of user will vary depending on their role and responsibilities within the organization.
Any user who uses database and takes benefits from the database is considered a Database Users. They can be programmers, scientists, engineers, business person or can be an employee. Database users are categorized based upon their interaction with the database. These are seven types of data base users in DBMS.
Database Administrator (DBA)
Database Administrator (DBA) is a person/team who is responsible for managing the overall database management system. i.e. the schema and also controls the 3 levels of database. The DBA will then create a new account id and password for the user if he/she need to access the data base.
DBA is also responsible for providing security to the data base and he allows only the authorized users to access/modify the data base. DBA also monitors the recovery and back up and provide technical support. The DBA has a DBA account in the DBMS which called a system or superuser account. DBA repairs damage caused due to hardware and/or software failures.
Naive / Parametric End Users
Parametric End Users are the unsophisticated who don’t have any DBMS knowledge but they frequently use the data base applications in their daily life to get the desired results.For example, online library system, ticket booking systems, ATMs etc which has existing application and users use them to interact with the database to fulfill their requests.
System Analyst
System Analyst is a user who analyzes the requirements of parametric end users. They check whether all the requirements of end users are satisfied.
Sophisticated Users
Sophisticated users can be engineers, scientists, business analyst, who are familiar with the database. They can develop their own data base applications according to their requirement. They don’t write the program code but they interact the data base by writing SQL queries directly through the query processor.
Application Programmers: These users are responsible for designing, developing, and maintaining software applications that interact with the database. They work with data models, schemas, and programming languages to develop custom queries, triggers, and stored procedures to retrieve, manipulate, and store data in the database.
End-users: These users access the database to retrieve, view, and modify data for their specific needs. They may use user-friendly interfaces such as web applications, desktop applications, or mobile apps to access the database. End-users typically have limited access to the database and only have permissions to access data related to their job responsibilities.
Data Analysts: These users have a deep understanding of data analysis techniques and tools and use the database to extract insights and identify patterns in data. They use data mining, statistical analysis, or machine learning algorithms to identify trends, create reports, and develop business strategies based on data-driven insights.
Executive Users: These users are high-level managers or executives who use the database to make informed decisions based on data-driven insights. They may use dashboards, reports, or other visualization tools to analyze data and identify trends to make strategic business decisions.
External Users: These users may include suppliers, partners, or customers who need access to the database for various reasons, such as managing orders or tracking inventory. External users typically have limited access to the database and are only able to view and modify data related to their interactions with the organization.
Each type of user has their unique needs, responsibilities, and access levels, and it's essential to set up appropriate security protocols and access controls to ensure the database's security, integrity, and performance.
