Defining an architecture1. Collect non-functionals2. Determine deployment environment3. Determine usage4. Select engineering principles5. Read between the lines6. Select technology7. Define reference architecture8. Build & adapt

Well-known Rich domain models Many frameworks Very flexibele× Lots of work× Lots of plumbing needed× Not using RIA frameworks× DTO conversion troubles× No eager loading
