Codd's Rules
Codd's Rules are a set of thirteen guidelines proposed by Edgar F. Codd to define what is required from a database management system to be considered relational, meaning it handles data in a structured and organized way. These rules cover aspects like data representation, accessibility, integrity, and consistency, ensuring that users can interact with the data intuitively and efficiently. For example, rules emphasize that data should be stored in tables and that all data must be accessible through a common language, typically SQL. Following these rules helps ensure reliable and effective data management in relational databases.

Codd's rules are a set of thirteen guidelines proposed by Edgar F. Codd for defining what is meant by a relational database management system (RDBMS). They emphasize how data should be organized, accessed, and manipulated. Key aspects include ensuring data is stored in tables, supporting data independence, allowing for straightforward querying, and ensuring that all data can be accessed consistently. Adhering to these rules helps to ensure that databases are reliable, flexible, and easy to use, ultimately leading to effective data management and retrieval.
