What is a duplicate check?

A duplicate check is a process used to identify and remove duplicate records or entries in a database or system. Duplicate checks are commonly used in various industries, such as banking, healthcare, and retail, to ensure data integrity and accuracy.

There are different methods and techniques for conducting a duplicate check, including comparing data fields, using algorithms to detect similar records, and implementing validation rules to prevent duplicate entries.

Duplicate checks are important for maintaining the quality of data and preventing errors in decision-making processes. By removing duplicate entries, organizations can improve efficiency, reduce storage costs, and enhance data analysis and reporting capabilities.
