Create data management layer for PSSM (Professional and Scientific Staff Management). Here are some of the requirements:

• Apply the rules of normalization to the class diagram to check the diagram for processing efficiency.
• Develop a clustering and indexing strategy.
• Describe how your strategy will improve the performance of the database.
• Describe the connectivity among the classes on the problem domain and data management layers. You should use class and communication diagrams to describe the connectivity among the classes on the problem domain, physical architecture, data management, and human computer interaction layers.

I have finished the parts necessary for this but no clue as to how to go about this?
