摘　　要：随着企业业务的不断发展,各行各业产生的数据越来越复杂,不仅表现在数据规模的增长,也表现在数据异构化的出现.以网络安全公司为例,公司在使用网络基础设施和数据库时产生的日志数据不仅规模量大,而且存储的数据字段差异性大,若没有一个统一的模型来处理这些数据,那么数据的集中利用和共享将很难实现.提出在元数据基础上对数据进行统一集成并最终形成数据资产目录的一种方法,先设计数据领域、设备类型、设备名、数据表名、数据字段名以及字段数据类型等元数据项,然后按元数据项层级构建数据资产树形目录结构,依据元数据项提供的上下文信息定位数据源,最后实现了一个基于元数据的网络数据资产目录系统.With the continuous development of enterprise business,the data generated by various industries is becoming increasingly complex,not only manifested in the growth of data scale,but also in the emergence of data heterogeneity.Taking a network security company as an example,the log data generated by the company when using network infrastructure and databases is not only large in scale,but also has significant differences in the stored data fields.Without a unified model to handle this data,it will be difficult to achieve centralized utilization and sharing of data.This paper proposes a method of unified integration of data on the basis of metadata and ultimately forming a data asset catalog.Firstly,this paper designs metadata items such as data domain,device type,device name,data table name,data field name,and field data type.Then,a tree-like directory structure of data assets is constructed according to the hierarchy of metadata items,and the data source is located based on the contextual information provided by the metadata items.Finally,this paper implements a network data asset catalog system based on metadata.
