摘　　要：采用变异系数法对28个数据库绩效综合评价相关指标进行权重计算,剔除重要性和相关性较小的指标,得到样本数据库综合绩效评价的23个最终评价指标体系及相应各指标的权重,并对各指标权重分布的合理性进行验证;然后结合灰色关联度分析法评价各样本数据库的综合绩效以及通过计算各样本数据库5个维度指标的关联度值分析影响各样本数据库绩效优劣的重要因素,从而找到提升数据库绩效的途径。The index weight of 28 comprehensive database performance evaluation indicators were firstly calculated with the coefficient of variation. Secondly, a final evaluation index system with 23 indicators and the corresponding index weight were achieved after culling the smaller correlation index. Then, the comprehensive performances of the sample database were evaluated with the gray correlation analysis method and the important factors affecting the performance of each sample database were analyzed with the gray correlation analysis method. Finally, the ways of improving the database performance were put forward.
