What is Data Integrity Constraints?
Data integrity constraints are rules you set up in a database to make sure the data is accurate and reliable. These rules prevent bad data from being entered into tables. Think of them as checks and balances that maintain the quality of your information by enforcing specific criteria like uniqueness, valid ranges, or required values.
