WORKFLOW ENCAPSULATION IN STATELESS ENVIRONMENTS

摘要

A system for running applications such as may be used over the internet separates the logical workflow processes of the application from views presented to a user. Separate process flow modules are used to provide state code for executing transactional applications. Logical views are designated by these modules in response to user input. Actual views presented to a user are derived from these logical views according to the status of the user and the communication channel over which the transaction is being performed. Process flow modules can be reused with different sets of user interface views to provide a variety of user interfaces without significant recoding.
