Delta record is the incremental (updated or inserted) load of data that is inserted or updated into a table in the database.
Delta detection compares new data from a source system with the last versions in the data warehouse to find out whether a new version has to be created.
In this video I have written SQL query to compare two tables with the same schema and found the new/modified records when comparing the two tables.
