12、發(fā)展和時(shí)間的推移，導(dǎo)致數(shù)據(jù)倉(cāng)庫(kù)項(xiàng)目的健壯性和可維護(hù)性呈幾何級(jí)數(shù)下降，給數(shù)據(jù)倉(cāng)庫(kù)的建設(shè)帶來(lái)大量的重復(fù)工作。1.2什么是元數(shù)據(jù)管理什么是元數(shù)據(jù)管理元數(shù)據(jù)最本質(zhì)，最抽象的定義為：dataaboutdata(關(guān)于數(shù)據(jù)的數(shù)據(jù))。而對(duì)于經(jīng)營(yíng)分析數(shù)據(jù)倉(cāng)庫(kù)而言，形象的定義為：元數(shù)據(jù)就是數(shù)據(jù)倉(cāng)庫(kù)元數(shù)據(jù)就是數(shù)據(jù)倉(cāng)庫(kù)的規(guī)范的規(guī)范。這些規(guī)范包括對(duì)各種指標(biāo)的定義、解釋?zhuān)话▽?duì)各表中數(shù)據(jù)的來(lái)龍去脈、數(shù)據(jù)的大小和格式的定義。元數(shù)據(jù)管理，就是要建立一套行之有效的規(guī)范以

13、及該規(guī)范的管控體系，實(shí)現(xiàn)從管理到查詢(xún)到綜合分析的全面管控，管理層次從接口到ETL處理、業(yè)務(wù)邏輯處理、結(jié)果展現(xiàn)處理和指標(biāo)分析的方方面面，構(gòu)成數(shù)據(jù)倉(cāng)庫(kù)應(yīng)用系統(tǒng)的核心和基礎(chǔ)。做到開(kāi)發(fā)者能?chē)?yán)格遵守規(guī)范，維護(hù)者和使用者有規(guī)范可查，有力的保障數(shù)據(jù)倉(cāng)庫(kù)項(xiàng)目的健壯性和可維護(hù)性。2.目標(biāo)分析目標(biāo)分析要走出目前的困境，有下面三個(gè)方面的問(wèn)題急待解決：2.1建立完善的指標(biāo)解釋體系建立完善的指標(biāo)解釋體系滿(mǎn)足用戶(hù)對(duì)業(yè)務(wù)和數(shù)據(jù)理解的需求，建立標(biāo)準(zhǔn)的企業(yè)內(nèi)部知識(shí)傳承的
