Database Selection Model Based on Fuzzy Comprehensive Evaluation

Along with the constant development of information technology, the database has become the basis of information resources management and development in the information-oriented society. Faced with the advantages and disadvantages of relational database and non-relational database, it is very important to provide a set of scientific options for database administrators. In this paper, a database selection model based on comprehensive evaluation method is proposed, which provides a reasonable database selection scheme for database administrators. The performance of increasing, deleting, modifying, querying are the primary indicator of this model, and the consumption of time, disk, CPU, I/O are the second indicator. The method of fuzzy comprehensive evaluation is applied to the establishment of database selection model, which is the innovation of this research.
