摘要：A simple OODBMS is implemented in an OOP languageBorland C++. It incorporates object identity andencapsulation via data abstraction. Objects and theiroperations are realised by the concept of class inC++. The DDL is constructed by C++ language. The DMLis formed from lots of C++ functions. The B-tree indexstructure is adapted for the index management of thedatabase. The main feature of the OODBMS is that itsupports object-oriented model and can manage variblelength-record (VLR) database. Based on this OODBMS,and combined with algorithms of photogrammetrY, imageprocessing and computer graphics, an object-orientedpictorial information system for photogrammetrY isbuil t.
