摘 要
元數(shù)據(jù)是用來描述、解釋、定位，使獲取、使用或管理更加容易的結(jié)構(gòu)化信息。元數(shù)據(jù)通常被稱為數(shù)據(jù)的數(shù)據(jù)或者信息的信息。目前，元數(shù)據(jù)管理主要應(yīng)用在藝術(shù)品、博物館、地理科學(xué)資源、電子文檔和多媒體等領(lǐng)域。實(shí)際上元數(shù)據(jù)本身的優(yōu)勢(shì)和特點(diǎn)能夠在網(wǎng)絡(luò)時(shí)代所有需要數(shù)據(jù)存儲(chǔ)與訪問的地方發(fā)揮出來。在企業(yè)對(duì)數(shù)據(jù)一致性和集中管理多種類別數(shù)據(jù)的需求越來越重要的情況下，元數(shù)據(jù)的理論和相關(guān)技術(shù)能夠更好的實(shí)現(xiàn)企業(yè)的目標(biāo)。
首先，本文從企業(yè)需求與數(shù)據(jù)共享標(biāo)準(zhǔn)等方面對(duì)項(xiàng)目背景進(jìn)行說明，對(duì)當(dāng)前的元數(shù)據(jù)標(biāo)準(zhǔn)應(yīng)用情況作簡(jiǎn)要的介紹。然后，本文將詳細(xì)闡述元數(shù)據(jù)的設(shè)計(jì)理論與方法，說明項(xiàng)目的理論基礎(chǔ)，并介紹本項(xiàng)目的技術(shù)背景。隨后，將闡述項(xiàng)目的方案與總體架構(gòu)，并介紹本項(xiàng)目的邏輯規(guī)劃。
最后，本文將重點(diǎn)介紹項(xiàng)目中的核心問題與解決方式，說明部分具有創(chuàng)新性的設(shè)計(jì)與實(shí)現(xiàn)，并對(duì)下一步改進(jìn)和完善的方向進(jìn)行展望。

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.

Key Words: Metadata, Metadata Modeling, Master Data, Relations and Restrictions, Structured and Unstructured Data Transformation, ETL
