This paper analyses the characteristics of Web-multidatabase transactions and associated transaction management issues. Current Webdatabase transaction management solutions are reviewed. Conclusions drawn are that these are currently too restrictive. Flexibility is required through nested flexible transaction strategies, with compensation, and contingency or alternative subtransactions. Furthermore, the classical ACID test of transaction correctness is over-restrictive and unrealistic in the Web context. A relaxation of the ACID test is proposed, based on semantic atomicity, local consistency, and durability, for resilient transactions, i.e., the SACReD properties. These conclusions motivate the authors ongoing research and development of a prototype CORBA-compliant middleware Web-multidatabase transaction manager based upon a hybrid configuration of open and closed nested flexible transactions.
