ETL之研究─以SAP ERP系統為例

商業智慧(Business Intelligence)係指包含使用者查詢、報表與分析、資料探勘及統計分析，協助企業主管掌握精準的資訊。商業智慧的核心是ETL，將各個來源端系統資料匯進商業智慧系統分析，但是ETL過程複雜且耗時。當今在企業資訊系統市場上德國SAP公司有最高的占有率，所以許多系統都需考慮與SAP系統做ETL，為了節省做ETL與設計cube的時間，SAP提供Business Content，其提供豐富的產業模型以及建置好的cube和報表。若順利的啟動Business Content 連接其他SAP資訊系統，將可大幅節省BI導入時間。本研究第一目的是釐清利用SAP BI系統中的Business Content與SAP 其他系統設定上的議題，以便順利進行 ETL，將資料完整的從其他SAP系統匯入至BI系統。本研究第二目的是依據資料新鮮度的限制以建置最短工作優先排程演算法為基礎來決定出執行delta load 的時機與順序，以求達到最短平均反應時間。本研究詳細的呈現SAP BI系統在連接設定以及匯入SAP ERP系統的營運資料過程，以提供需要運用SAP系統進行商業智慧分析的人員有一個參考依據。

Business Intelligence including query, data mining and statistical analysis, ETL is the core of Business intelligence, the various sources of information exchange into the end system business intelligence systems analysis, but the ETL process is complex and time consuming. SAP system is the most popular in the Enterprise information system markets, so many systems are to be considered with the SAP system as ETL process. In order to save time and design of the cube, SAP provides Business Content, included a wealth of industry models, cubes and reports. If the successful start-Business Content to connect to other SAP information system will greatly save time BI import. The first purpose of this study is to clarify the use of SAP BI system with SAP Business Content in the system settings on other topics, in order to smooth ETL, to complete data import from other SAP systems to the BI system. The second purpose of this study is based on data freshness constraints to build the minimum hours of work based on priority scheduling algorithm to determine the timing and implementation of delta load order, in order to achieve the shortest average response time. This study presents the detailed SAP BI system in the connection setup and operation of SAP ERP systems to import data process to provide the required use of the SAP system for business intelligence analysis staff have a reference.
