研究目的：,数据”是信息系统的“血液”。当企业信息化发展到一定程度时，数据管理（MDM，Mater Data Management)必会被提升为企业信息化管理的一个重要管理领域。数据管理的好坏程度，从很大程度上 左右着企业信息化进程，决定着企业信息化成果的品质。主数据管理是一个标准化规范制定与系统集成的工 作，牵涉部门广，牵涉系统多，同时涉及历史数据处理等问题，实施难度很大，为了能有效地推动项目，必须分 步实施，主数据管理是指用于生成和维护主数据的一整套规范、技术与方案，用来保证主数据的一致性、完整 性和准确性。 研究结论：( 1)主数据管理就是实现各业务系统间共享数据，它是各业务系统间数据交换的基准;（2)主 数据管理目标是使各业务系统在获取基准数据时，能够保证数据是最新的、一致的、准确的，能够实时进行各 系统间数据验证;（3)主数据是企业信息化管理的核心数据，更应该得到有效、全面、统一及妥善的管理; (4)主数据管理的四大要素是数据集成、数据共享、数据治理、数据质量;（5)本研究成果的应用将统一各业务 信息应用系统的基础数据。

Research purposes ： The M Data" is the 11 blood" of information system. When the enterprise information develops to a certain extent，the data management ( MDM，Master Data Management) will be promoted to an important management field of enterprise information management. The quality of data management，to a large extent affects the process of enterprise information，and determines the quality of enterprise information results. Master data management is a standardized specification design and system integration work，which has many involved departments and systems， and relates to the processing of historical data and other issues，so the implementation is very difficult. In order to effectively promote the project implementation， the distributed implementation must be carried out. The master data management refers to the create and maintain a set of standard，technology and scheme of the master daa，to ensure the consistency，completeness and accuracy of thedata. Research conclusions ：( 1) Themaster data management is to realizedata sharing among different application systems， and it is the benchmark of tlie data exchange among the reference systems. (2) The main goal is to make the business data management system in the acquisition of baseline data，to ensure data is up - to - date，consistent，accurate，able to perform data validation of the system in real time. ( 3 ) The master data is the core data of enterprise information management, should be more effective;comprehensive; unified and proper management. (4) The four elements of master data management is data integration; data sharing，data management and data quality. (5) The application of research results will unify the basic data of busines information application system.
