Business Rules for Concurrent E-commerce Transactions

Business rules are a cornerstone of the consistency management of e-commerce data. The concurrency of transactions by multiple customers of e-commerce services (e.g., seat reservation systems) is indispensable for most of such services. However, the enforcement of business rules may falter due to extant inconsistencies of legacy data and integrity violations caused by the concurrency of transactions. To avoid this, we propose an inconsistency-tolerant approach to business rules enforcement for e-business applications in which business rules are expressed by database integrity constraints. The extension overcomes problems related to persistent integrity violations of stored data in e-commerce systems with concurrent transactions.
