IT C170 - Performance Assessment.
IT C170 - Performance Assessment. / IT C170 - Performance Assessment. Section 1 First Normal Form I gathered all the data from the sales invoice and created an unnormalized dataset. I determined the primary key that provided me with a unique value for all my records in this table. I used composite primary keys because both keys would be able to uniquely identify all the data in the table. Finally, I removed all the repeating groups and made the address atomic by creating separate fields for each one.
