Get the analysis finished product demand is the line design UML (with class diagram) or the first design database?

I first design the database, UML generally draw a component diagram to represent the line. Usually do not draw the class diagram, the person responsible for the assembly to draw their own. Because the database model diagram at this time can master the project overview, but also through the field and foreign key relationship settings grasp the general logical relationship, this is almost. As for the class diagram is too trivial, and the first plan can not catch the change, the second developer and your ideas may be self-defeating, third, think too much old fast.

Prototype simple, directly design the database, and UML diagram. Prototype complex first good prototype design, and then design the database, design class diagram These two must be mutual influence, need to constantly improve
