Due to the increase of database application areas, new database systems for advanced applications are required to handle multi-media data such as pictures, voices, software, knowledge etc. and their relationships. In our research project we have investigated advanced data models for such advanced applications.In the first year, we made basic research on data models. Realization of secure systems using an object oriented database model was discussed. How to handle object migration problems among classes, representation of various database constraints, and realization of multi-media databases are discussed.In the second year, how to modify conventional object-oriented databases in order to apply various areas was discussed. A system which generates hyper-card data from fulltext papers was developed. Design procedures for object oriented databases were also developed.In the last year, multi-project security model is developed and generalization of object-oriented model is proposed. Interaction problems of object migration and schema evaluation is also discussed. Proposal on improvement of the model considering various applications is also given.

由于数据库应用领域的增加，需要用于高级应用程序的新数据库系统来处理多媒体数据，例如图片，声音，软件，知识等。在我们的研究项目中，我们研究了此类高级应用程序的高级数据模型。第一年，我们对数据模型进行了基础研究。讨论了使用面向对象的数据库模型实现安全系统。如何处理类之间的对象迁移问题，各种数据库约束的表示以及对多媒体数据库的实现。第二年，如何修改常规的面向对象的数据库以应用各个领域。开发了一种从FullText论文生成超级卡数据的系统。还开发了针对对象数据库的设计程序。去年，开发了多项目安全模型，并提出了面向对象的模型的概括。还讨论了对象迁移和架构评估的相互作用问题。还提出了考虑各种应用程序的改进模型的建议。
