A procedure implemented to identify identical or highly similar records within a dataset or system is a mechanism for ensuring data integrity. For instance, a customer database may undergo this process to prevent the creation of multiple accounts for the same individual, even if slight variations exist in the entered information, such as different email addresses or nicknames.
The value of this process lies in its capacity to improve data accuracy and efficiency. Eliminating redundancies reduces storage costs, streamlines operations, and prevents inconsistencies that can lead to errors in reporting, analysis, and communication. Historically, this was a manual and time-consuming task. However, advancements in computing have led to automated solutions that can analyze large datasets swiftly and effectively.
