In view of normalization of different data pools, the author has studied normalization processing method of the erp different data pools, has established the normalization mapping rule using ebnf, and has given a data type transformation method based on two levels of mapping . this thesis has designed a normalization rules engine as well 針對(duì)不同環(huán)境下數(shù)據(jù)源的歸一化問(wèn)題,研究了erp不同數(shù)據(jù)源的歸一化處理方法,運(yùn)用ebnf建立了歸一化映射規(guī)則,并提出了基于兩級(jí)映射的數(shù)據(jù)類(lèi)型轉(zhuǎn)換方法,在此基礎(chǔ)上設(shè)計(jì)了歸一化規(guī)則引擎。
