There are plenty of research on heterogeneous databases, particularly on retrieval method from semi-structured databases, however, the number of projects for actual operation was not so many. In this research, communication method and environment for operation of molecular biology databases are discussed. The four most referenced databases, i.e., Genbank, Prosite, PIR and PDB, are selected for this research target and the files of these four databases are stored in computes in our lab. Agent programs are coded using our previous work results and have XML format interface.The programs which access these databases are provided as Java applets. Users can use these programs to access the databases. The communication between objects is implemented by HORB objects. Agents can move around databases and collect necessary data. For this agent control, we studied aglets which is invented in IBM.Furthermore, as an application of our research results, we studied the basis for colleting personal learning record in every PC in the educational computer lab, the way to assure the user authentication in a LAN socket environment, and how to utilize those records for education.

对于异构数据库，特别是半结构化数据库中的检索方法的研究已经很多，但实际操作的项目并不多。本文讨论了分子生物学数据库的通信方法和运行环境。四个最常引用的数据库，即，本研究选取了Genbank、Prosite、PIR和PDB四个数据库作为研究对象，并将这四个数据库的文件存储在实验室的计算机上。代理程序采用我们以前的工作成果编写，具有XML格式的接口，访问这些数据库的程序以Java applet的形式提供。用户可以使用这些程序访问数据库。对象之间的通信由HORB对象实现。代理可以在数据库中移动并收集必要的数据。为了实现这种代理控制，我们研究了IBM公司的Aglet，并将其应用于教学机房中，研究了在每台PC机上收集个人学习记录的依据、在局域网套接字环境下保证用户身份认证的方法以及如何利用这些记录进行教学。
