An RDBMS (Relational Database Management System) is a type of database management system that is based on the relational model. It is designed to efficiently manage and organize structured data using a set of predefined rules and relationships.<\/p>\n\n\n\n

In an RDBMS, data is stored in the form of tables, which consist of rows and columns. Each row in a table represents a single record or data entity, while each column represents a specific attribute or data field. The relationships between tables are established through keys, such as primary keys and foreign keys.<\/p>\n\n\n\n

Some key features of an RDBMS include:<\/p>\n\n\n\n

    \n
  1. Data Integrity: RDBMS ensures data integrity by enforcing constraints and rules on the data, such as primary key uniqueness, foreign key relationships, and data types.<\/li>\n\n\n\n
  2. ACID Compliance: RDBMS guarantees ACID properties for transactions. ACID stands for Atomicity (transactions are treated as a single unit of work), Consistency (transactions bring the database from one valid state to another), Isolation (transactions are isolated from each other), and Durability (committed transactions are permanent).<\/li>\n\n\n\n
  3. Query Language: RDBMS provides a standardized language for querying and manipulating data, known as SQL (Structured Query Language). SQL allows users to retrieve, insert, update, and delete data from the database.<\/li>\n\n\n\n
  4. Scalability and Performance: RDBMS systems are designed to handle large volumes of data and provide efficient data retrieval and manipulation operations. They often include indexing mechanisms and query optimization techniques to improve performance.<\/li>\n\n\n\n
  5. Data Security: RDBMS provides built-in security mechanisms to protect data, including user authentication, authorization, and data encryption.<\/li>\n<\/ol>\n\n\n\n

    Popular examples of RDBMS systems include Oracle Database, MySQL, Microsoft SQL Server, PostgreSQL, and IBM DB2. These systems are widely used in various applications and industries to manage and store structured data effectively.<\/p>\n","protected":false},"excerpt":{"rendered":"
