Exam 70-300 Objective 5

Tested myself on Exam 70-300 (Analyzing Requirements and Defining Microsoft .NET Solution Architectures) Objective 5 (Creating the Logical Design) and received only 37%.  I've got a bit of study to do, specifically:

1. Create the logical design for the solution.
   
   • Deliverables are: logical object model; high-lvel UI design; logical data model
   • In UML, parent-child relationship is depicted as a Generalization
2. Create the logical data model
   
   • Program manager: drive the logical design deliverables
3. Validate the proposed logical design
   
   • Testers: define high-level test plan/ validate logical design against conceptual design
   • Don't use Windows application when you can use Web Service: can log onto it; can activate it via system process.
