In this paper,we present the strategies for complex objectmanagement and its SQL language in our own developed engineering databasemanagement system called EDBMS/2.

In this paper, we study profitably the version management problem of complex objects including the mathematical model of version, logical design of version control machanism and difference sto.

Overall United Coordinating must be stood out when we manage the complicated object, but Overall United Organizing and Planning can play the particular role in the higher level of the management and planning; and it has very strong complementary and synergetic relationship with other management- planning subject.
