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? CORBA-based Agent (15) POSTECH DP&NM Lab.
