在线材料数据库进展与NIMS/MatWeb案例研究

Recent Progress of Web-enable Material Database and a Case Study of NIMS and MatWeb

在线材料数据库是现代信息技术背景下产生的获取信息的新模式,在新材料设计、材料选择、决策咨询等方面应用广泛。能够及时掌握在线材料数据库新动态,准确、高效利用在线材料数据库进行科学研究与工程应用研究尤为重要。本文介绍了在线材料数据库的最新进展,并以NIMS和MatWeb国际著名在线材料数据库为例,从数据服务内容、检索功能、检索结果的处理等方面进行分析与对比,以期对科研人员准确选择以及高效利用在线材料数据库提供帮助。未来在线材料数据库的发展趋势为:Web集成一站式服务,数据类型更多、数据规模更大、数据更规范,基于数据库的衍生信息服务更完善。

Web-enable material database （MDB） is a new model to obtain information based on the de- velopment of modern information technology, and is widely used in the fields of new material design; material selection; strategic decision consultation and so on. It is very important to grasp timely the latest tendency of web-enable MDBs and to utilize accurately and efficiently web-enable MDBs for sci- entific research and engineering application. Consequently the latest developments of web-enable MD- Bs were introduced in this paper; NIMS and MatWeb, two internationally famous online MDBs, were also studied. The paper expounds it from the following aspects： data service contents; search func- tion; retrieved results processing etc. The aim of this paper is to help researchers select and use web- enable MDBs precisely and efficiently. In the writer＇s view, the future developments of web-enable MDBs are as follows： one-stop service by web integration; more data types; more data quantities; more standards; as well as more complete information service derived from the database.
