Normalization is a technique to organize the contents of the table for transactional database and data warehouse.
First Normal Form :
Seeing the data in the example in the book or assuming otherwise that all attributes contain the atomic value, we find out the table is in the 1NF.
Second Normal Form :
Seeing the FDs, we find out that the K for the table is a composite one comprising of empId, projName. We did not include the determinant of fourth FD, that is, the empDept, in the PK because empDept is dependent on empId and empID is included in our proposed PK. However, with this PK (empID, projName) we have got partial dependencies in the table through FDs 1 and 3 where we see that some attributes are being determined by subset of our K which is the violation of the requirement for the 2NF. So we split our table based on the FDs 1 and 3 as follows :
