摘要
信息编码具有信息标识标准化的能力,但是在信息表达上能力不足,限制了信息编码的作用。据此,提出编码主数据模型,在保持编码标识能力的基础上,增加了信息实体的属性元素项,丰富了信息实体的描述。将编码主数据模型结合具体的信息实体,通过模型转换,实现编码主数据模型到数据库结构的映射,并编程加载数据,构建企业标准编码数据库,提供数据服务。企业的实际应用表明,该模型在信息标识和表达方面具有优势,有很好的工程应用价值。
Information coding can standardize the information identity, however, it is lack of capacity in information expression, which limits the role of information coding. Accordingly, a main code data model is proposed. It increases information entities attributes and enriches information described while keeping information identity. Through model mapping on specific information entities, the main code model becomes database structure. An enterprise standard code database is built for data services after data is loaded by programming. Through practical applications in the enterprise, the model has advantages on identity and expression, and also has good value of engineering applications.
