Abstract:

P-sets which is composed of internal P-sets and outer P-sets, is a set pair and has dynamic characteristic. Based on Psets, the concepts such as data set,　-data set,　F-data set and (,F)data set, and then -data set theorem,　F-data set theorem,　(,F)-data band theorem, data set recovery theorem,　(,F)data identification theorem and identification criterion are proposed. By using those results, applications of　(,F)-data in an information system are presented. P-sets is a new theory and a new method in the research of a dynamic information system.

Key words:  P-sets; (,F)data set;　F-data theorem;　-data theorem;　(,F)-data band; identification theorem
