What is Database Administrator?
As Data Management becomes more autonomous, the DBA position is shifting from database-centric to data-centric. General database upkeep is made easier with augmented data management, machine learning (ML), and artificial intelligence (AI), which reduces the amount of manual labor. This frees up the DBA to focus on more strategic activities like assuring regulatory compliance and enhancing data flow performance. Many believe that the DBA’s role will expand from managing a few database instances and systems to managing many more. DBAs will focus on enterprise data rather than specializing in a few database technologies as the number of data sources grows.
The speed at which the DBA’s role evolves will be determined by a company’s capacity to adapt and implement new data technology. Because many firms still utilize outdated relational database systems, some DBAs will continue to work with them. The function of the DBA, on the other hand, will continue to evolve in most businesses. DBAs will be involved in more high-level data analytics and DevOps responsibilities as a result of this.
Who is a DBA what are the responsibilities of a DBA
Database administrators (DBAs) are largely in charge of the subsystem’s databases. DBAs in some firms are given the SYSADM special group permission, which allows them to do nearly anything in the DB2® subsystem and provides them control over all of the subsystem’s databases. In some companies, a DBA’s authority is restricted to specific databases.
The DBA develops the data object hierarchy, starting with the database and moving on to tablespaces, tables, and any indexes or views that are needed. This individual also establishes the referential integrity definitions and any constraints that may be required.
The physical database design is essentially implemented by the DBA. Part of this entails doing space calculations and calculating how big the actual data sets for the table and index spaces should be, as well as designating storage groups.
DBAs can use a variety of tools to aid them in their work.
The DBA may be in charge of issuing authorizations to database objects, though this is sometimes delegated to a separate security management group.
A database management system is defined by the centralization of data and the control of access to that data. One of the benefits of this centralization is that consistent data is available to several applications. As a result, stricter control over that data and its use are required.
The DBA is in charge of ensuring that control is implemented correctly. Indeed, having a central point of control for a centralized database is required to reap the full benefits of adopting one. We will confine ourselves to a review of the tasks and responsibilities of a DBA because the actual implementation of the DBA function is reliant on a company’s organization. The DBA team will need to have experience with both application and systems programming.
