What should we do?
• Documentation for design result
– Design of DB
– Put consistency in use of interface & parameter
– Further detailed design using private interface and attribute
• Implementation Issue
–
–
–
–
Development environment?
Job assign?
What management application?
What can we reuse from our previous implementation and others?
