When constructing a database, two rules are followed by the database designer to ensure the integrity of keys. Describe each rule and discuss common violations. All tables in any system must save data for a solitary entity. Any entity typically reveals a real-life event or object.

To hold on to the relational model, every row and column should be identified from a unique or distinctive identifier.
