关系查询语言的事件驱动计算
Event Driven Computations for Relational Query Language
摘要：
本文论述了一种扩展的计算模型，它使用参数化的数据对象的实体的家庭，并反映了这个问题的初步轮廓。在此基础上，本文选取了若干主题，进行了简要的分析和整理，以涵盖一个普遍性的问题.作者打算更多地讨论特定的主题，它们的相互联系和计算意义作为一个小组提案，所以这篇论文还没有被评估为封闭的期刊论文。为了节省篇幅，所有的技术和实现功能都留给以后的文件。数据对象是一个原理图实体，由部分函数建模。类型的概念由依赖于事件和类型的变量域扩展。可变域是从潜在的和示意性的个体构建的，并根据事件的序列生成有效的类型家族。每一个有效的类型都由相对于事件或脚本而言是真实的个体组成。如果类型依赖于脚本，则附加数据对象的相应视图，否则生成快照。由此确定的类型给出了类型化变量的上限，使得局部范围是事件驱动的，从而产生实际个体的家族。使用可拓关系和意向关系来扩展查询语言的表达能力。
英文摘要：
This paper deals with an extended model of computations which uses the parameterized families of entities for data objects and reflects a preliminary outline of this problem. Some topics are selected out, briefly analyzed and arranged to cover a general problem. The authors intended more to discuss the particular topics, their interconnection and computational meaning as a panel proposal, so that this paper is not yet to be evaluated as a closed journal paper. To save space all the technical and implementation features are left for the future paper. Data object is a schematic entity and modelled by the partial function. A notion of type is extended by the variable domains which depend on events and types. A variable domain is built from the potential and schematic individuals and generates the valid families of types depending on a sequence of events. Each valid type consists of the actual individuals which are actual relatively the event or script. In case when a type depends on the script then corresponding view for data objects is attached, otherwise a snapshot is generated. The type thus determined gives an upper range for typed variables so that the local ranges are event driven resulting is the families of actual individuals. An expressive power of the query language is extended using the extensional and intentional relations.
