In this video, we will understand the fundamental concept of metadata validation, which is vital for maintaining data accuracy and integrity.
Metadata checks are essential for ensuring data quality, and we'll navigate through three key types:
Datatype Check: This validation ensures that data aligns with its designated data type
Constraints Check: Through metadata validation, we uphold the integrity of data by enforcing constraints such as uniqueness and foreign key relationships.
Data Length Check: Many data fields have predefined lengths, and metadata validation verifies that data conforms to these expected formats.
