The reasons of estabilshing a stochastic weather data model as outdoor conditions in analysing a thermal process of air-conditioning system are discussed and a new model-multidimensional time series model, with the Beijing area weather data as an example, is made. Thereupon, the method producting this model and the theory on which the model based is also discussed in detail. Thereby, the conditions which the model must be satisfy with are listed. Finally, some practical...

The latest international research trend in DBMS is to go beyond specific data models toward the common DB system construction. After a detailed analysis of ANSI/SPARC and Paolo Paolini's general structures, this paper introduces the concept of abstract operation, under which a variety of specific data models can be unified on the "internal schema-conceptual schema-abstract operation" structure.

在深入剖析ANSI/X3/sPARC体系和Paolo Paolini一般结构的利弊之后,本文提出抽象操作的概念,把各具体数据模型统一在“内模式—概念模式—抽象操作”的结构上。

This paper introduces a nation-wide computer users'information retrieval system with Chinese characters.This system is able to store and retrieve all technical information of the users and the computers used in our country.It is useful for management and reasonable utilization of the computers in the whole country. The program of the system is divided into several functional modules;Chinese characters are stored in the form of their addresses where their codes of dot matrices are stored;the data model used in the system is similar to the hiera- rchical data model in the data base and index technique widely used,.thus ensuring readability,ease of maintenance and retrieval speed of this system. The system has been implemented on the microcomputer Sigma-10 and used by Computer Technical Service Company of China.
