You are a human resources officer at a software organization with development centers in different cities. The organization stores personnel records for staff members in a database at the head office. The development centers hire staff at regular intervals, and the centers send you the personnel data for the staff members that they hire.
You add the personnel records to a spreadsheet file, and you use the file data to update the employee database. You are concerned that the current file might contain duplicate identities.
You design a mapping to perform identity analysis on the employee records. You configure a Match transformation to search for duplicate identities in the spreadsheet file. You must also verify that the file data does not duplicate any employee data in the master database. You configure the Match transformation to compare the file data with the master data that you store for the organization employees.
Because the database is a master data set, you store the index data for the staff records in a persistent data store.
