【摘要】：随着物流行业的快速发展,物流信息化的要求不断提高,物流产业转型迫在眉睫,而作为提高物流信息化水平、推动物流产业转型升级的重要途径,物流信息平台的建设显得尤为重要。在物流信息平台的建设中,数据资源是关键,目前迫切的需要一种能对数据资源进行高效管理与使用的方法。本文在物流信息平台的建设中引入元数据的概念,通过制定元数据的方法实现对物流信息平台中数据资源的管理,对物流信息平台的建设和使用意义重大。本论文研究并实现了元数据在物流信息平台中的应用和元数据维护工具。首先在元数据的规范基础上制定了物流信息平台中元数据的规范,根据物流信息平台中元数据的规范研究和开发了一套元数据的管理工具,实现了对元数据的抽取、查询、存储和维护等功能,然后针对主题元数据开发了模板的应用方式,为主题元数据的录入提供了可扩展性强、易于维护的方式,最后为物流信息平台的第三方程序开发人员提供了一个基于元数据访问物流信息平台的接口,开发人员可以根据元数据找到并访问物流信息平台中的数据资源,这个接口的实现为开发人员提供了简单、易用的开发环境。本文围绕元数据在物流信息平台中的应用,制定了元数据规范,开发了元数据管理工具,提供了应用和扩展功能,使元数据的应用能获得较好的效果。
[Abstract]:With the rapid development of logistics industry, the requirements of logistics informatization are constantly raised, and the transformation of logistics industry is imminent. As an important way to improve the level of logistics informatization and promote the transformation and upgrading of logistics industry, The construction of logistics information platform is particularly important. In the construction of logistics information platform, data resource is the key. At present, there is an urgent need for a method that can efficiently manage and use the data resource. In this paper, the concept of metadata is introduced into the construction of logistics information platform, and the management of data resources in logistics information platform is realized by making metadata, which is of great significance to the construction and use of logistics information platform. This paper studies and implements the application of metadata in logistics information platform and metadata maintenance tools. Firstly, the metadata specification in the logistics information platform is established on the basis of the metadata specification. According to the metadata standard in the logistics information platform, a set of metadata management tools are developed, and the metadata extraction and query are realized. Storage and maintenance functions, and then for the topic metadata development template application mode, for the topic metadata input provides a strong scalability, easy to maintain the way, Finally, an interface based on metadata to access the logistics information platform is provided for the third party program developers of the logistics information platform. The developers can find and access the data resources in the logistics information platform according to the metadata. The implementation of this interface provides a simple and easy-to-use development environment for developers. Around the application of metadata in the logistics information platform, this paper formulates the metadata specification, develops the metadata management tool, provides the application and the extension function, enables the metadata application to obtain the better effect.
