One of the most widely used relational database management systems (RDBMS) by enterprises worldwide is Oracle Database. It is an effective technology that enables businesses to swiftly and effectively store, handle, and retrieve enormous volumes of data. Nevertheless, a qualified individual known as an Oracle Database Administrator is needed to maintain an Oracle Database in good working order (DBA).
The efficient, secure, and downtime-free operation of the database is the responsibility of an Oracle DBA. They are primarily responsible for setting up, maintaining, and guaranteeing the performance, security, and scalability of the Oracle Database software. They also manage database performance, monitor the system for problems, and carry out backup and recovery duties.
The job of an Oracle DBA can be divided into three broad areas: database design, database administration, and performance tuning :
- Database Design: An Oracle Database that satisfies the needs of the business is designed and implemented by a DBA in collaboration with application developers. They define tables, develop a database structure, and make connections between them. Moreover, they guarantee the database's normalization and effective data storage.
- Database Administration: To maintain the database operating efficiently, a DBA completes a variety of administrative activities. They set up users and roles, administer security, and uphold data integrity while installing and configuring the Oracle Database software. Also, they keep an eye on the database to spot and fix problems like sluggish searches or hardware failures.
- Performance tuning: A DBA is in charge of enhancing the Oracle Database's performance. They keep an eye on the system to spot bottlenecks and tweak the database settings to boost speed. Moreover, they collaborate with programmers to streamline SQL queries and guarantee that the database can accommodate massive amounts of data.
