A data element is used for the semantic definition ( field label ) of a table fields 數(shù)據(jù)庫技術(shù)角度的字段類型,在數(shù)據(jù)庫中是以啥形勢(shì)存放的
The result is likely to be a language with a more complex semantic definition than that of a relational language such as sql 其結(jié)果很可能產(chǎn)生其語義定義比關(guān)系語言(如sql )更加復(fù)雜的一門語言。
He implements the system in three layers : first , in the semantic definition layer , it establishes the data structure construct and semantic model ; second , in the data processing layer , it integrates the financial data and the other business data into the convenience analysis form according to etl ( extract transform loading ) action ; finally , in the presentation layer it implements slice , rotation and drill down / up action . so it meets the requirement of financial analysis and financial management for enterprise 在語義定義層完成企業(yè)數(shù)據(jù)結(jié)構(gòu)的搭建和語義建模工作;在數(shù)據(jù)處理層通過一系列的etl (析取、轉(zhuǎn)換、加載)操作,實(shí)現(xiàn)了對(duì)企業(yè)財(cái)務(wù)數(shù)據(jù)及相關(guān)業(yè)務(wù)數(shù)據(jù)的有效整合,并且最終形成便于分析的多維數(shù)據(jù)體系:進(jìn)而在數(shù)據(jù)表現(xiàn)層實(shí)現(xiàn)了對(duì)目標(biāo)數(shù)據(jù)的切片、旋轉(zhuǎn)、鉆取等多種手段的分析操作,以滿足企業(yè)財(cái)務(wù)分析、財(cái)務(wù)管理以及決策支持工作的需要。
