What do we mean by Data Integrity?
Data isn’t static. Many things will happen to your data throughout is life cycle. It can be transferred to other systems, altered and updated multiple times.
Each time a processing activity is undertaken there is a risk that your data may become compromised. This is where data integrity comes into play. The process involves the maintenance of data throughout its entire life cycle.
The overall intent of any data integrity technique is to ensure that data is recorded exactly as intended. It must remain intact and unchanged between various iterations of the data file and across multiple systems.
