摘要
面向对象数据库支持复杂的数据类型,语义贴近现实,因而有广泛的应用前景。数据字典是数据库的骨架,因此数据字典的建立至关重要。通过对面向对象数据库和关系数据库中数据字典结构的研究,建立和实现了面向对象数据字典;用十字链表数据结构存储数据字典,并给出了算法。用十字链表的方法存储数据字典结构清晰,插入和查询方便。
Object-oriented database support complex data and its semantic is similar to our world. With this merits, object-oriented database is applied widly. Data dictionary is the skelecton of object-oriented database so that to establish data dictionary is very important. By studing data dictionary of object-oriented database and relational database, how to establish object structure＇s data dictionary and how to implement structure of class with intersection are discussed; Using data-structure of intersection save data dictionary is easy to insert and query data.
