RDBMS, abbreviated as Relational Database Management System, is a type of software technology that allows users to store, manage, and retrieve data in a structured manner. It is based on the relational model, which organizes data into two-dimensional tables consisting of rows and columns, with each row representing a record and each column representing a field or attribute of that record.
An RDBMS provides a structured approach to storing data, ensuring data integrity and minimizing redundancy. It implements a set of rules and constraints, known as ACID (Atomicity, Consistency, Isolation, Durability), to ensure the reliability and consistency of data. ACID compliance guarantees that database transactions are processed reliably and accurately.
In an RDBMS, data can be accessed and manipulated using Structured Query Language (SQL), a widely-used and standardized language for managing relational databases. SQL allows users to define the structure of the database, perform data retrieval, modification, and deletion operations, as well as define relationships between different tables.
RDBMSs have become a fundamental component of various applications and industries, ranging from banking and finance to e-commerce and healthcare. They offer numerous advantages like scalability, data security, ease of data retrieval, and efficient management of large datasets.
Some popular examples of RDBMSs include Oracle Database, Microsoft SQL Server, MySQL, and PostgreSQL.
