減稅廣告沒有告訴你的真相





您是否對於近來各大電視台突然出現密集的減稅廣告,感覺到不知所云呢?事實上,由工 商團體出資的這三支廣告,刻意迴避稅制與國家總體教育、農業、社會福利、醫療、體育、文化等重要支出密切相關,只將稅制與經濟透過極度簡化的連動圖象,企圖洗腦民眾支持減稅。


 但是,工總推出減稅廣告的目的只在於藉以要脅政府降低遺產稅、贈與稅、營利事業所得稅、未分配盈餘加徵10%等等的富人稅而已。


 這是一場不對稱的對抗,公平稅改聯盟沒有龐大的資金,在各電視台各時段,與財團鉅富進行廣告抗衡。但我們仍然能夠透過網路,透過社會大眾對於公平社會的堅持,讓事實真相得以公開。


 經由這支廣告,我們將告訴您,有錢人大喊減稅論述,他們的真正目的!


歡迎您 將這支廣告轉寄或連結在您的blog上,讓更多人,看清美麗謊言背後的真相。

[Data Warehouse] 專攻歷史資料分析的資料庫系統


專攻歷史資料分析的資料庫系統

資料倉儲一詞,於1990年由資料倉儲之父Bill Inmon首次提出,是以分析與查詢為目的所建置的系統,這種系統能整合及運用資料,產生對決策者有用的情報。
Data Warehouse,DW
能重新萃取、呈現企業交易資料面貌的資料倉儲系統


資料倉儲一詞,於1990年由資料倉儲之父Bill Inmon提出,他認為DW的目的在於整合及運用資料。這種系統存在的目的,就是將所有資料儲存在同一個地方,管理這些資料的進出,並且透過各種分析方法。如線上分析處理(OLAP)、資料採礦(Data Mining)對這些資料進行分析,再應用在決策輔助系統(Decision Support System,DSS)、主管資訊系統(Executive Information System,EIS),幫助決策者能從大量的資料中,分析出有價值的資訊,以利擬定策略與快速回應,建構出商業智慧(Business Intelligence,BI)。


早在1960年代,大型主機便已開始被用來定期產生報表。直至1970年代,第一個以資料分析為目的產品Express誕生,之後在1995年輾轉由Oracle買下,直到今日,這項技術仍然是Oracle資料倉儲產品的一部分。


1980年代有大型公司開始建置獨立的決策輔助系統,其實就是現今資料倉儲的前身。1990年代資料倉儲系統,又因為以下三種電腦技術的發展,而變得更加實用:主從架構、平行計算與網際網路的興起。


主從架構讓系統可以區分成前端與資料處理兩部分。平行計算增加了主機資料處理的能力,使資料倉儲系統可以處理並且容納更多的資料。而網際網路讓資料倉儲系統可以透過網路傳遞資料。


另一位與Bill Inmon並駕齊驅的Ralph Kimball以資料倉儲的功能為出發點,並不特別規範資料倉儲裡頭所包含的資料類型做任何規範。因為實際上資料倉儲系統,並不是只含交易資料,如果要達到有效的分析,資料勢必經過整合。因此結合Bill Inmon與Ralph Kimball的解釋是更為恰當的,「資料倉儲是以分析與查詢為目的所建置的系統,這種系統能整合及運用資料,產生對決策者有用的情報。」


 資料倉儲結構概念圖


Data Mart
資料超市
資料超市是資料倉儲的一種特殊形式,同樣包含對作業資料的快照,方便使用者能基於經驗與歷史資料進行決策。和資料倉儲最主要的差別,在於資料超市是預先定義好的,而且是具體的,同時資料也是分組並配置好的。


在單一企業中可以有多個資料超市,每個資料超市會與一個或多個商業單元相關聯。如果某些資料超市的設計上,是使用相同的資料和規模,這些資料超市就會是相關聯的。


Operational Data Store,ODS
操作性資料商店
一個經過整合的分析系統,以支援前端操作為目的。如同資料倉儲,操作性資料商店中的資料是主題導向、經過整合的,由於操作性資料商店是用來支援前端的操作系統,所以上面的資料必須是即時的,也就是需要經常被更新、補充的。


此外,由於前端操作系統經常需要較為詳細的資料,因此操作性資料商店的資料必須包含所有詳細資料,才能達到它的目的,這一點和資料倉儲不同。


Waterfall Methodology
瀑布式
系統建置的方法之一,在每個階段都需要進行到結束的程序,下一個階段才能開始。這種做法呈階梯狀,由分析、設計、建置、測試到系統完成,很自然地銜接到下一個階段,如瀑布的水流經好幾個落差一般。早期資料倉儲都採用此法,開發團隊會花很多時間以符合所有提出的要求。且累積的資料量非常龐大,建置的時間較長,等系統上線時,企業的運作時常已經改變,先前的工作可能已經毫無意義了。


Spiral Methodology
旋轉式

與瀑布式皆為系統建置的方法,但是完全不一樣。旋轉式中每個階段所花的時間較少,且整個系統的建置是不斷在進行的。每一個循環(分析->設計->建置->測試)結束,使用者即評估目前系統的狀況,進而確認下一步的方向。


和瀑布式相比,旋轉式系統上線的速度更快、一次的花費不會太高,而且使用者的需求可以迅速反應在系統上,不會因建置時間過長而產生需求不符合現實的狀況。


ETL,Extraction、Transformation and Loading
資料提取、轉換及匯入
這是資料整合的3個步驟,由資料來源讀取出資料,將它們轉換成適合分析的型態,並且將它們匯入資料倉儲系統。這個過程在建立資料倉儲架構中是不可互缺的一環,通常還要搭配著資料清潔(Data Cleaning)將系統源頭許多未經整合的、不允許的、遺失的或者錯誤的資料,在匯入資料倉儲之前重新整頓,因為源頭是錯誤的資料,之後發布的也是錯誤的資訊。所以,完成ETL以後,資料的分析處理作業才可以繼續進行。


Metadata
中繼資料
中繼資料是描述資料本身特性的資料,如果有完整的中繼資料,將使管理資料倉儲系統更加容易。


中繼資料橫跨整個資料倉儲系統架構,無論是資料來源、資料提取、臨時資料儲存區,都需要有中繼資料。


中繼資料的儲存與管理是倉儲系統最重要的一環,卻也是最容易被忽略的,主要原因是使用者不常直接使用到中繼資料,且大部分的資料倉儲專案計畫中,並沒有提到中繼資料。


Fact Table
事實表格
資料倉儲系統中儲存歷史資料的資料表格,這些都是資料倉儲的核心資料。


如果以一個商用資料倉儲來看,事實表格的資料是以交易為中心的資料,它們可以是物品的銷售,信用卡交易和利息與利潤等資料。
資料倉儲中的事實表格是資料庫中處理得最頻繁的資料表格,也是操作最為頻繁的,所以事實資料表有時可以龐大到占據超過1TB的空間。


Dimension Table
維度表格

用來定義事實表格中的欄位,例如員工姓名、性別或其他項目等。
使用上和正規化的過程相似,同樣都是擷取有用的資料以加快處理速度。維度表格所包含的資訊,一般可以指出如何從事實表格中取得有用的材料。因此簡單來說,維度表格是用來記載事實表格中所包含資料的意義。
維度表格通常很小,且只含有幾個資料列。所以資料倉儲一般只會有少數幾個事實表格,卻會有很多個維度表格。


Multi-Dimension
多維度
多維度是人們分析資料的特定角度,可以用來表示特定地區、時間、產品、銷售量下的資訊。多維分析是指可以對多維形式所組織起來的資料,透過各種分析方法剖析,方便使用者可以從多個角度去觀察資料庫裡頭的資料。資料庫結構中,位於中心的稱為事實表格,外圍的稱之為維度表格,而一般資料倉儲只會有少數幾個事實表格與多個維度表格,呈現星狀結構,所以多維度資料庫結構又稱為星狀資料庫結構。

[White Paper] Enterprise SOA Management: Using an Architectural Approach to Foster Collaboration and Analysis for SOA Initiatives


Description:
Service-Oriented Architecture is acclaimed as a method to implement an organizational methodology based on composite applications. To be effective, SOA's abstracted approach requires clear definition at the business and application design levels, as well as a way to synchronize between them.


To properly implement and manage the SOA environment, a structured approach has been proven to bridge the gap between business and IT, becoming an efficient business language for communication and an effective method to map and plan the complexity of the deployable applications. Modeling provides the means to explicitly relate the highlevel business objectives with the specific capabilities each set of services can deliver, facilitating construction and maintenance of comprehensive applications that meet the business and design goals.


Due to its ability to visually represent the entire landscape, both business and technical, the model-driven approach to SOA is a powerful, flexible way ensure that the company's operations can keep pace with the changing practices of its environment.

[White Paper] Five Best Practices for Improving Software Development and Testing


Description:
With the growth of software complexity and the reliance of business on IT, the expectations and challenges facing test and development labs have correspondingly increased. Today, these labs are facing a mix of strategic and tactical goals that seem to be ever increasing. All this compounds the pressures on delivering quality software to production, or to market quickly.


Virtual lab automation (VLA) reduces labor-intensive manual tasks necessary in test and development labs through automation. VLA allows test and development lab processes and infrastructure to be streamlined and centrally managed. This whitepaper discusses how VLA is transforming the test and development lab, and provides best practices for automating the test and dev process to maintain or strengthen your competitive advantage by getting better products to market faster.
