碩士 === 國立中正大學 === 資訊工程研究所 === 90 === Nowadays most traditional relational databases are not able to handle complex applications. But thanks to the success of object-oriented programming, the object-oriented data model has become a natural descendant of semantic data models used in entity-relationship modeling. Our object-oriented database server takes ideas from object-oriented programming concerning the creation and manipulation of objects, as well as ideas from database research concerning the sharing and the long-term storage of large numbers of objects. In this thesis we describe the implementation of an object-oriented database server based on Java for storing and retrieving object-oriented data as well as relationships between objects. Currently, this server can process Java Remote Method Invocation (JRMI) calls that define, edit, or query persistent classes and objects. We have also implemented our storage system based on B-tree index and cache management to increase disk access efficiency. Moreover, this server will provide complex data types such as sets, lists, and arrays to model the data of objects, which makes our data model more natural than the relational data model.
