Hi @asadamjad thanks for your question! This sounds like you would use the ChangeDetector transformer to compare two datasets, check out this article explaining how to use it: https://community.safe.com/s/article/change-detection-2
As well, if you need update or delete your data after checking the data check out this article: https://community.safe.com/s/article/data-loading-updating-and-deleting
