Abstract:	傳統的資料庫設計都是為了解決企業線上交易所需。資料倉儲讓決策者快速從不同角度分析資料，隨時掌握企業營運狀況，以增強企業的競爭力。目前資料倉儲系統大部分未特別考慮共時控制與如果線上交易資料更新時，資料倉儲如何迅速同步更新的問題。在這個計畫，我們提出一個資料倉儲資料結構，它可從snapshot建構資料倉儲。我們設計了無死結的可共時修改或查詢此資料倉儲的操作。這些共時操作的正確性(序列性)與無死結性也都被證明操。 The goal of the conventional database is aimed at the online transaction processing of the enterprises. Through the help of the data warehouse, the decision maker can survey the transaction data from different views, monitoring the operations of the corporation and then strengthening the competitive advantage. Most of the current data warehouses are constructed without special considerations for the concurrent control and synchronized update. In this project, we propose a data structure for the data warehouse at first. We construct the data warehouse from the data gotten from the snapshot. Designs are made of deadlock-free operations that concurrently update or query the data warehouse when a transaction is made. The correctness of these concurrent operations and the deadlock-free property are proved.
