Data Warehouse Technology Application On Digital Library Construction

Since the early 1990s the United States last century scientists first raised Digital Library (Digital Library) concept, and scholars in the global context of a wave of the digital library research. Period was fruitful, but also found a lot of problems. Involving one of the main issues is : digital library as modern computer technology, network technology, information processing technology integrated use the product as a higher form of library development, in the present circumstances to play its fundamental role of technology from the constraints. Digital Library is accompanied by a wave of information technology, and information contained in the wave of digital technology, information storage technologies, database technology, network communications technology and hypertext and hypermedia technologies for the information resources in digital libraries, has become a "double-edged sword." On the one hand, it provides for the development of library development opportunities and endless make broad space for development, it allows the library resource base in the traditional collection of literature resources constraints, the Library can provide readers with more colorful information. At the same time, because of the disorderly nature of the network of information resources, open, dynamic, diversity, large capacity, users wide, strong and interactive features such as the uneven quality of a problem, to the day-to-day management of library and information integration has brought unprecedented challenges. Faced with this situation, some scholars began to introduce digital library data warehouse technologies to solve existing problems to look forward to realize the standardization of digital library resources, the decision-making process more scientific and personalized service characteristics. The data warehouse is based on a so-called information management and integration technologies. He is to be effective it is in Heaven classified information collation and use the resulting demand. For data storage research from the last century began at the end of the 1980s, so far only a dozen years. And the traditional data warehouse primarily to be used by enterprises and research and development. Its main objective is to use technology to achieve business leaders in science policy-making, marketing research, and so on. Therefore data warehouse technology in the digital library building is necessary? Feasible? And, how are they going to? These are academic colleagues eager to explore the library. Based on the above idea select the "digital library building data warehouse technology applied research" as Thesis, and in the paper focused on the introduction of a data warehouse technical possibility and necessity of building digital libraries. Combined with the features of digital libraries in the digital library of data storage technology are introduced and made notes. Finally on digital libraries for data storage logic modelling preliminary exploration. Because of the study must be based on a computer basis, therefore, for I must be a professional research restrictions, if properly owed to the Department, if experts criticized me.
