Design and Development of Self Built Database of University Library Based on Cloud Computing

Abstract

Cloud computing technology is a series of fusion products of computer technology development to a certain stage, which will bring revolutionary and far-reaching influence to various fields including digital library. The purpose of this paper is to study the design and development of self built database of University Library Based on cloud computing. Firstly, this paper summarizes the concept of the impact of digital resource integration in detail, focusing on the analysis of the technical characteristics and basic structure of cloud computing technology. This paper puts forward the structure of database model, and analyzes the design of self built database system of personalized University Library Based on the demand of users and system performance. According to the requirements of the project development, the experimental results show that in the data integration module, column storage stores and queries the data in columns. Each table consists of a set of page chains, each page chain corresponds to a storage column in the table, and each page chain stores one or more values of the column. HNG index is a combination of b-tree index and bitmap index in the storage. The data is stored in bit mode and sliced vertically according to bit. A large part of data storage can be compressed due to sparsity, and I0 can be reduced. It is suitable for parallel calculation of total and average values.
