As the advance of hardware systems and their application technologies, database systems are requested to have highly advanced functionalities. As a result, it has become important to support the development of advanced application programs by combining the facilities of deductive databases, which provides a deduction mechanism based on a firm mathematical foundation, and those of object-oriented databases, which provides a flexible modeling capability of the real world. Based on this background, in this study, we focused on the application areas in which advanced knowledge processing capabilities such as natural language processing systems and expert systems are required.For these areas, we aimed at establishing a programming methodology to provide the capabilities of both advanced reasoning and flexible programming. More specifically, in order to combine the knowledge processing mechanism and the program execution mechanism in a highly flexible way, we examined each of these mechanism … More s closely and then tried to integrate them so as to satisfy the advanced applications' requirements.In our employed approach, we consider that the notion of inheritance plays a bridge across over the different two mechanisms, i.e., the inheritance reasoning is done in the knowledge processing mechanism and the result is reflected to program execution mechanism. In this approach, we can handle the knowledge processing part and the program execution part separately, while we can make use of both capabilities in an integrated way. As a result of our research in these two fiscal years, we have established the foundations of database programming language for advanced use of IS-A knowledge in three aspects : reasoning, programming, and application development. We feel convinced that the IS-A knowledge will play an important role in developing intellectual applications in the near future, and therefore our study of the last two years is considered to be very meaningful for such advanced applications.

随着硬件系统及其应用技术的发展，对数据库系统提出了更高的功能要求。因此，通过结合演绎数据库的功能来支持高级应用程序的开发变得非常重要，演绎数据库提供了基于坚实数学基础的演绎机制，而面向对象数据库提供了对现实世界的灵活建模能力。基于此背景，本研究重点关注自然语言处理系统和专家系统等需要先进知识处理能力的应用领域。对于这些领域，我们的目标是建立一种编程方法来提供高级推理和灵活编程的能力。更具体地说，为了将知识处理机制和程序执行机制以一种高度灵活的方式结合起来，我们对每一种机制都进行了更细致的研究，然后试图将它们集成起来，以满足高级应用的需求。在我们采用的方法中，我们认为继承的概念在两种不同的机制之间起着桥梁的作用，即继承推理在知识处理机制中完成，结果反映到程序执行机制中。在这种方法中，我们可以分别处理知识处理部分和程序执行部分，同时我们可以以集成的方式利用这两种功能。由于我们在这两个财政年度的研究结果，我们已经在三个方面为高级使用IS-A知识建立了数据库编程语言的基础：推理、编程和应用程序开发。我们相信，在不久的将来，is - a知识将在开发智力应用方面发挥重要作用，因此我们过去两年的研究被认为对这种先进的应用非常有意义。少
