The best way to perform logical database modeling is to use strong guidelines that are developed by an expert in relational data modeling.
You could also use one of the many relational database modeling tools that is supplied by vendors, but it is important to remember that using a tool to migrate your logical model into a physical model does not mean that the physical model is the most optimal for performance. It is acceptable to modify the physical design to improve performance provided the logical model is not compromised.
DB2 objects must be designed for availability, ease of maintenance, and overall performance, as well as for business requirements.
