A Multi-agent Approach to SACReD Transactions for E-commerce Applications Muhammad Younas, N. H. Shah, and Kuo-Ming Chao   View Paper (PDF)   Return to Agents Abstract E-commerce systems provide Web users with different facilities such as online banking, online (window) shopping, and online auctions. However, behind the provision of these facilities are certain requirements posed by the e-commerce applications including: data consistency, concurrency, dynamic behaviour, fault tolerance and high availability. Our research identifies that traditional ACID and agent transaction models are inadequate. We propose a new approach that enforces novel transaction correctness criteria, called SACReD (Semantic Atomicity, Consistency, Resiliency, and Durability) using a new multi-agent model. Initial evaluation shows that the new approach potentially meets the aforementioned requirements of e-commerce applications. DiSC'03 © 2003 Association for Computing Machinery
