Relaxation of ACID properties in AuTrA, The adaptive user-defined transaction relaxing approach

In this paper we introduce a new model for supporting transactions in a web environment. The model offers business benefits by increasing throughput of transactions. This is achieved by supporting the relaxation of various combinations of ACID properties according to the user’s requirements and the business needs. The model aims at improving transaction throughput at the same time as maintaining a reliable user service. A distinctive feature is that any or all of the ACID properties may be maintained or relaxed depending on user need. We tested the proposed model through various experiments and our results show that the proposed model is capable of increasing transaction throughput while supporting user and business needs.
