Abstract: Since the beginning of the 21st century, the proportion of databases has been rising greatly
in library resources acquisition. It is of considerable interest to libraries to evaluate the performance of
e-journal databases, the most important e-resources. As a result, databases evaluation has been extensively
studied. After summarizing and analyzing the existing evaluation researches, this paper resolves the model
into three key elements: evaluation indicators, data collection and processing, and indicator weights. Using
the practical experience of Shanghai Jiao Tong University Library, the paper compares evaluation results
by changing the model elements, in order to provide useful reference for the establishment and application
of scientific, reasonable and practical database evaluation models.
