Introduction to DBA
A Database Administrator (DBA) is responsible for managing, backing up, and ensuring the availability of data stored in databases. The primary functions of a DBA include designing database schemas, ensuring data integrity, tuning performance, managing access, and troubleshooting issues. DBAs work with both SQL databases (like MySQL, PostgreSQL, Oracle) and NoSQL databases (like MongoDB, Cassandra). For example, a DBA might design a database schema for an e-commerce application to efficiently handle product catalogs, customer information, and transaction records.
