“A database is a structured system used to efficiently store, manage, and organize data. It enables secure storage, retrieval, updating, and deletion of information for users and applications. Databases are essential for handling user accounts, transactions, and inventories in digital systems. They are categorized into relational (SQL), which structures data in tables, and NoSQL, which offers flexibility for unstructured data. Popular database management systems include Firebase, MongoDB, PostgreSQL, and MySQL. A database internship provides hands-on experience with these technologies, helping aspiring professionals build expertise.”
