The Application and Implementation of Metadata In Masterdata Management
Abstract
Metadata is structured information that describes, explains, locates, or otherwise makes it easier to retrieve, use, or manage an information resource. Metadata is often called data about data or information about information. Metadata Management is widely used in some domain like art, museums, geography resources, e-documents and multimedia presently. In fact, in this network age, as its own advantages and characteristics, metadata could play well in all needs of data storage and access. While in the situation of the business demand of data consistency and centralized management of multiple data types becoming increasingly obvious, the theory and related technology of metadata can help achieve business goals better.
In the first, this article will introduce the background of the project including business requirements and data-sharing standards, and briefly describe the applications of current metadata standard. Then, this article will elaborate the design theory and method of metadata, for describing the theoretical foundation of this project. And then, the technical background of this project will be introduced. Subsequently, the article will set out the general framework and the logic programming. Finally, this article will focus on the core issue and the solution of this project, illustrate some new ideas and implementations, as well as improvements can made and the outlook of this application.
