A system and method providing an environment for the composition, generation, integration and execution of business processes and/or transactions over a distributed computing-based network. In a preferred embodiment, a business process expert develops a business model by using a network browser to access the composition environment via the network. The preferred embodiment includes a Composer and a Player. The Composer allows a business process engineer to model the processes, process rules and data structures of an entity upon the basis of a plurality of software resources. The Player executes the modeled processes and access relevant data in real-time, according to rules and resources as related within a software structure generated by the business process engineer. The preferred embodiment dynamically constructs web pages based on the process, rule and data definitions prepared by a business process engineer/expert and does so through a Process Interpreter and Grammar Engine so as to encapsulate all the software resources necessary to complete the desired business process without the need of people programming, scripting or coding. Pages are constructed only when required, ensuring that the solutions are flexible, error free and based upon the most current business practices, providing agile, integrated, error free and real-time software solutions capabilities.
