基于元数据的油气信息管理系统

非结构化数据在信息总量中所占的比例远大于结构化数据，是油气信息管理过程中的宝贵数据资产，如何对这些非结构化数据有效管理和应用是新型油气信息管理系统建设的重要内容之一。为了实现对油气信息资源中包括非结构化数据在内的综合数据高效管理与集成应用，从应用元数据技术角度，一方面对非结构化数据进行定义和详细描述，另一方面以数据库元数据为核心对系统框架进行构建，从而设计了一种新型的油气信息管理系统。系统实现了油气信息综合数据的存储与管理，而且可以对异构数据源进行有效集成应用，有良好的灵活性和扩展性。

Oil and Natural Gas Information Management System Based on Metadata

Unstructured data occupies the proportion of total information amount more than structured data, which is valuable data asset during management of oil and natural gas information. How to manage the unstructured data is an important content for developing new oil and natural gas information management system. In order to realize efficient management and integration application of unstructured oil and natural gas data, this paper puts forward a new oil and natural gas information management system from application of metadata technology view. In the new information management system, the unstructured data is defined and described by metadata, and the system framework is designed based on metadata of database. The new system has good flexibility and extensibility, which not only can efficient manage unstructured data of oil and natural gas, but also can realize integration application of heterogeneous data sources.
