Why does MySQL not confirm with Codd's Rules?
MySQL does not fully conform to Codd's Rules, which outline the principles of a relational database, primarily because it employs certain features that deviate from these foundational principles. For instance, MySQL supports non-relational features like stored procedures, triggers, and various data types that can lead to inconsistencies in data integrity. Additionally, its use of various storage engines can result in differing behaviors that do not align with the strict requirements of Codd's Rules, such as the requirement for data independence and logical data integrity. These deviations make MySQL more flexible and practical for many applications, but at the cost of strict adherence to relational theory.
Does MySQL run by Codd's 12 rules?
MySQL does not fully adhere to Codd's 12 rules for relational databases. While it implements many relational concepts, such as data integrity and the use of SQL for data manipulation, it lacks complete adherence to rules like the support for a true relational model, as it allows non-relational features like stored procedures and triggers. Additionally, it supports various data types and functionalities that may not align strictly with Codd's principles. Therefore, while MySQL embodies many relational database characteristics, it is not a strict implementation of Codd's 12 rules.
