Relational Databases (RDBMS)

Relational Database Management Systems (RDBMS) provide a structured approach to storing and managing information by organizing data into tables made up of rows and columns. These tables can be connected through defined relationships, allowing data to be stored, accessed, and maintained in a consistent and organized manner. This section introduces important concepts such as primary and foreign keys, normalization, ACID transactions, and SQL-based data querying, explaining how they contribute to data integrity and dependable database operations.

RDBMS technology combines well-defined data structures with powerful tools for retrieving and managing information, making it suitable for applications where accuracy and consistency are critical. Systems such as MySQL, PostgreSQL, and Oracle are commonly used in areas ranging from financial platforms to large-scale enterprise software. The central focus of an RDBMS is to maintain reliable relationships between data while ensuring that information remains accurate, consistent, and trustworthy as the system grows.
