摘　　要：目前,人力资源管理系统的数据库大多基于实体关系模型进行设计与实现。该模型虽有利于描述实体、属性以及实体间的关系,但不利于存储动态变化的实体及其关系等信息,更不利于进行数据验证等工作。随着数据库技术的发展,一种中心锚链模型(AM)应运而生,其能够强调时间元信息在实体、属性以及实体之间关系中的表达和运用,通过AM的数学模型和UML模型扩展对各类复杂场景的描述能力,将AM描述的数据表示为Schema而非SQL语句集合,并利用Schema合并支持上层模块的融合与增量开发,由此补全了实体关系模型的短板。因此,AM对于数据库的设计和升级具有明确的工程应用价值。At present,the entity relationship model(ERM)is mostly used to design and implement the database in information management system. Although the entity relation model can describe the entities,attributes and relationship between entities,it neither conducive to store the dynamic entities and relationships nor conducive to works such as data validation. In addition,fat tables in the entity relationship model are not conducive to the upper application modules to update themselves. With the development of database technology,the Anchor Model(AM)is provided. It emphasizes the expression and application of the meta-information time in entities,attributes and relationship between entities. Description ability of all kinds of complex scenes is extended by AM’s mathematic model and UML model. The data of AM description is the collection of Schema,not SQL language. And merger of schema are used to support the upper modules of the integration and incremental development. Therefore,AM complements the weakness of ERM and has a clear engineering value for the design and promotion of the database.
