What are the responsibilities of the DBA and the database designers?

Although the DBA does not need to know anything about the contents of the database, it does not have to know enough CPU, disk, memory, and network bandwidth so that proper backups are performed (and periodically checked) need to confirm. They should monitor the load on the system and inform developers / designers that the system is overloaded.

Database designers / developers work with end users to verify that the database contains all the information the user needs. You also need to design physical tables and indexes so that queries are executed as soon as needed. They tell you the amount of space required for the DBA and the speed at which table / index expansion is expected.

If the query (screen and report) is not fast enough, designers.developers need to check the bottlenecks in the code and the DBA needs to check the memory, I / O, or bottleneck in the network. Designers need to create new indexes or add statistics to the database to speed up the execution of queries. These objects require DBA space, and you can change table definitions for creating / updating statistics.

The database administrator or DBA is important to the company. DBA's job is to design, maintain and support the database. In order to design the database infrastructure, the DBA needs to be familiar with the database platform such as Oracle. Therefore, getting good Oracle certification is very important for DBA. You can also use SQL authentication. In addition, the database administrator needs to understand exactly how the database platform is affected by the hardware specification. Database administrators need to evaluate process loads and other variables in order to design databases and create database solutions. As part of its maintenance work, the DBA needs to keep the database online and to be accessible to future end users. You also need to maintain database security and performance. The DBA monitors the size, accessibility, and speed of the database and ensures that the database has adequate backups and is safe.

Database administrator (DBA) roles, responsibilities, and responsibilities: Database administrator (DBA) has many roles and responsibilities. He is responsible for the administration, protection and processing of the database system. Before explaining the role and responsibility of DBA, we need to understand who the DBA really is and what it means. A database administrator is a group of people or people responsible for managing all activities related to the database system. This work requires sophisticated expertise from a single human or group of people. Because there is little opportunity for only one person to manage all database system activities, the company always has a group of people who are responsible for the database system.
