This allows for the automation of tasks and validations that ensure data integrity and application logic is followed. For instance, a business rule can be set to automatically update fields based on certain conditions or to prevent a record from being saved if it does not meet specific criteria. Because these rules operate directly on the records being affected in the database, they are critical for maintaining the business logic related to data manipulation.

Client scripts are executed in the user's browser and are used mainly for validations and interactive behaviors before data is sent to the server.

Therefore, business rules stand out uniquely for their direct
