In order to facilitate the scientific research workers to know the impact factor of SCI (Science Citation Index) journal in their own field, the program realizes a filter of more than 11,000 kinds of SCI journals in a certain field that are published annually to get impact factors of the journal that are related to their own subject. SCI journal involves nearly 100 research fields, but each researcher only cares about one or two research areas. At present, the scientific research workers mostly use Excel tool to handle the journal data by hand. Thus it needs a huge workload and the accuracy cannot be guaranteed. The batch data of workbook in SCI journal dataset can be fast processed by VB6.0 (Visual Basic6.0) program, and the procession has the characteristics of high accuracy and high-speed has a wide range of application.
