Definition
The relational database model is a framework for storing data in tables, where each table consists of rows and columns. It facilitates the organization, manipulation, and retrieval of data through relationships among tables.
Summary
The relational database model is a foundational concept in data management, allowing for the organization of data into structured tables. Each table consists of rows and columns, where rows represent individual records and columns represent attributes of those records. This model supports relationships between tables through primary and foreign keys, ensuring data integrity and facilitating complex queries. Normalization is a key process in relational databases that minimizes data redundancy and enhances data integrity. By organizing data into separate tables and defining relationships, databases become more efficient and easier to manage. Understanding the relational database model is essential for anyone looking to work with data in a structured and effective manner.
