Referential integrity is really important for keeping data quality high in schools and colleges. It helps make sure that the relationships between different tables in a database stay correct, which is essential for getting accurate information when needed.
Consistency: This means that if there is a foreign key in one table, it should match a primary key in another table. For example, when a student signs up for a class, that class ID must be found in the course table.
Accuracy: This helps cut down on errors in the data. Studies show that schools with strong referential integrity have up to 30% fewer mistakes in their data.
Data Updates: This ensures that when information gets updated or deleted, everything stays in order. For instance, if a course needs to be removed and there are students enrolled in it, the system will either let you know about it or prevent the action to keep everything accurate.
By following these rules, schools and colleges can keep their data accuracy above 95%.
