Additional Information

Data Integrated

• Data integrity is used to eliminate the data redundancy

Data Conversion

• It translates individual computer objects and data types from one format to another, data migration transfers entire databases or programs from one location to another. Data migration often called data conversio

Data inconsistency

Unique indexes 

• It helps to maintain data integrity by ensuring that no two rows of data in a table have identical key values.
