织女星信息网格客体的全生命周期研究

Research on Full Lifecycle of Vega Information Grid Object

信息网格的研究中,关于客体的研究还相对较少且不成熟。文章结合中科院计算所织女星信息网格的工作,对信息网格客体——有效关系、虚拟关系和物理关系,运用全生命周期的方法进行了研究。文章提出了一种形式化表示方法,来刻画客体各个阶段的内部、外部行为和特点,其形式为:OLC｛OPERATOR,DATASCHEMA,OPERATION,CONTEXT｝。该方法具有通用性,能够合理、有效的描述信息网格客体的全生命周期过程。

Researches on information grid especially about object is very scarce, and yet not weB-rounded. This paper is based on the research work of the Vega Information Grid, and investigate the full lifecycle of information grid object-- effective relation,virtual relation and physical relation. An abstract method is proposed in this paper to describe the exterior ,interior behavior and feature of the information grid object at all its stages. Its format is： OLC {Operator, Data Schema, Operation, Context}. This method is universal, can soundly and effectively describe the full lifecycle process of the information grid object
