This paper decomposes materialized views maintenance into ods / db interface and dw / ods interface. multiple data sources with concurrent updates may result in update anomalies of the materialized views. so at ods / db interface this paper introduces an improved nested transaction model - based transaction concurrency control mechanism to maintenance views in ods on line
本文把視圖的一致性維護問題分解到三層結構的ods / dw和dw / ods兩個介面上分別實現，並且引入視圖生成樹的概念，在ods / db介面處採用基於改進嵌套事務模型的並發控制機制，聯機維護ods的數據，大大提高了視圖維護過程中的並發度和靈活性。 -

This article describes the design scheme of message oriented middleware rodc : overall design conformed to jms standards ; using wal protocol and wal _ p algorithm combined with nested transaction model in transaction processing ; release mode supporting peer - to - peer mode and pub / sub mode. management and decision system in tobacco industry of state tobacco bureau is a large distributed system. this article describes the data transformation platform scheme based on mom rodc
在深入分析本領域內消息中間件基本演算法的基礎上，本文採用wal協議與嵌套事務模型結合的wal _ p演算法進行事務處理，利用點對點（ peer - to - peer ） 、發布/訂閱（ pub / sub ）進行發布模式設計，同時計遵循jms消息中間件規范進行總體設計，設計實現了一個消息隊列中間件系統rodc ，並將rodc應用到了煙草行業的生產決策系統之中。 -
