WS Transaction (WSTx) is a specification developed by BEA, IBM and Microsoft that indicates how transactions will be handled and controlled in Web Services. The transaction specification is divided into two parts - short atomic transactions (AT) and long business activity (BA). Based on the requirement of the application being developed, the developer implements the protocols of one of the above approaches.
Also known as Web Services Transactions
Web services belong to different organizations and hence take longer time to collaborate and achieve a task. An RDBMS-based transaction just needs a few seconds/minutes to execute, whereas Web services-based transactions may even run for days together. Even if one Web service fails, the entire transaction fails. These types of transactions cannot use a central authority since they use the Internet to communicate, which is impossible to manage.
