逻辑和物理模型同步变更规则研究

Research on Synchronization Change Rule for Logical and Physical Model Structure

目前,绝大多数企业的逻辑模型和物理模型还处于一种初级的手工管理阶段,即使部分企业采用了电子化的管理,也仅局限于对逻辑模型的管理,企业很少将逻辑模型变更与物理模型变更进行同步考虑。文中通过对逻辑模型的各种变更情况进行梳理,制定了一套规则及算法并对规则和算法进行定义,保证了逻辑模型和物理模型的一致性,该规则的定义不仅方便企业对数据的管理,而且保证数据在逻辑和物理的一致性。最后将构建的规则运用到油田企业数据字典的管理中,取得了很好的应用效果。

At present, the logical model and physical model in most enterprises are still in a primitive manual management phase. Even if parts of enterprises adopt electronic management, which are only limited to logical model, they rarely take logical model changes into account with physical model changes. Through collating various logical model changes situations, a set of rules and algorithms are made and defined. The definition of the rules will not only facilitate the management of enterprise data, but also ensure data consistency in the logical and physical model. Meanwhile the data management of enterprises becomes convenient. At last the rules constructed are applied to oilfield enterprises data management, and achieved very good application effect.
