摘要
同生物一样,数据也具有进化过程。本文参照生物进化论的观点,给出一种数据进化过程管理模型——数据基因模型。在数据基因模型中,数据进化过程中产生的信息称为数据的遗传信息,它们被保存在数据基因中。通过数据基因的遗传和变异来记录数据的特征及与其它数据的关系。该模型可用于企业信息处理、审计事务处理等对数据来源、去向需要清楚了解的应用中。本文给出了数据基因模型的基本概念、性质,并给出了模型的一个实例。
Like life in biology, data is in the journey of evolution. According to life evolution theory, a model to manage the evolving information of data, Data Gene Model, is presented in this thesis. In this model all evolving information of data are named as genetic information of data, and keptin data gene. And data gene will transmit or mutate with the varying of data. So that most information about data like origin, creator, travel experience, relation with other data and so on can be obtained from its data gene. This model can be used in applications that need much information about evolution of data, for example enterprise information modeling, audit system. Several aspects of this model have been defined in this thesis, including the basic concepts such as data gene, data gene sequence and data genome, relationships of data genes and data genomes. And an instance of this model is also given.
