What is Data Integrity Check?
Data Integrity Check refers to the process of verifying and maintaining the quality and consistency of data stored in a database or data lakehouse. It involves various techniques and mechanisms to identify and correct any potential errors, inconsistencies, or anomalies in the data.
How Data Integrity Check Works
Data Integrity Check works by implementing a set of rules, constraints, and validation processes on the data. These rules can be defined at the schema level or applied to individual columns or fields. The process typically involves data validation, error detection and correction, data cleansing, and data profiling.
