在传统的实化视图维护时,数据源把增量数据以XML文档的方式报送给数据仓库,数据仓库从此文档中解析出数据,利用JDBC完成对实化视图的更新.文中提出在数据源把增量数据封装成序列化对象存储于文件中再报送给数据仓库,而数据仓库从文件中读出对象,利用Hibernate直接把对象更新到实化视图.通过两种方案性能的比较,表明后一种方案是可行并且更加高效的.

Traditional materialized view maintenance, the data sources send the data warehouse the incremental data packed in XML document file. The data warehouse extracts the incremental data from this file, and then updates the materialized view with the JD-BC. In this paper, we put forward that the data sources encapsulate the incremental data in serialized objects and store them in files, and then submit it to the data warehouse. While the data warehouse reads the objects from the file and updates the materialized view with Hibernate directly. By contrast the latter solution is viable and more efficient.
