Abstract: An exemplary system is adapted for developing, testing, and operating payments and funds transfer systems, such as, for example, issuing systems, acquiring systems, and/or payment networks/systems. A model content repository stores elements for system models. An integrated development environment allows users to access the model content repository and design models. A deployment manager is adapted to compile and test models that have been defined and stored in the model content repository. The compiled code is executed in a platform runtime environment. Information that is collected from an executing system is communicated to the integrated development environment where the information may be presented to a user.
