Abstract: An Xbase transaction processing system that allows Xbase and SQL clients to operate against an Xbase file set on a server computer with commit/rollback transaction behavior that protects the data integrity of the Xbase file set against corruption due to the failure of one or more client computers. The system includes a server network communication means, an Xbase transaction protocol interpreter, an Xbase transaction management means, and an Xbase data file execution means. The communication means is configured to receive Xbase transactional commands from the network and to present server responses to the network. Software interfaces attach the network communication means to the protocol interpreter, the protocol interpreter to the transaction manager and the transaction manager to the file execution means.
