VALIDATION RULE Meaning and
Definition
-
A validation rule, in the context of computer programming and database management, refers to a set of predefined criteria or conditions that are applied to data input or data modifications in order to ensure accuracy, integrity, and consistency of the information stored in a database or system.
Validation rules act as a form of data validation mechanism that check user inputs against predetermined rules or constraints. These rules can be defined by the system administrator or database designer to ensure that data entered into the system meets specific requirements. These requirements might include data type, length, format, range, or relationship with other data fields.
When a validation rule is applied, it examines the entered data or updates and compares it against the predefined criteria. If the data satisfies the defined rules, it is accepted and stored in the database. However, if the data fails to meet any of the specified conditions, the validation rule triggers an error or warning message to indicate that the input or modification is invalid.
Validation rules are essential for maintaining data quality and database integrity. They help to prevent incorrect, incomplete, or nonsensical data from being stored and ensure that the information in the database remains accurate and consistent. By enforcing data validation through validation rules, organizations can rely on the correctness and reliability of the data stored in their systems.

Etymology of VALIDATION RULE
The term "validation rule" consists of two parts: "validation" and "rule".
The word "validation" is derived from the Latin word "validus", meaning "strong" or "powerful". In English, it first appeared in the late 16th century and is associated with the act of making something legally or logically valid.
The term "rule" comes from the Old English word "rēgel", which means "straight stick" or "straight line". It later evolved to refer to a principle or regulation that guides behavior or governs a specific domain.
When combined, "validation rule" refers to a principle or guideline that ensures the legitimacy or correctness of something, typically used in the context of programming or data management systems.
