1. A computer-implemented method, the method comprising: generating, by a processor, a plurality of business process patterns representing business logic associated with one or more of a plurality of business objects; obtaining a plurality of code portions that correspond to one or more of the plurality of business process patterns, the plurality of code portions being coded in a scripting language and stored in a script repository; defining at least one extension point for each business process pattern, each extension point representing an interface, within the business logic, in which to insert one or more of the plurality of code portions into processor-compiled architecture in a software application; in response to receiving, at the processor, a request to execute a service associated with the software application, determining portions of the service that include business logic to be carried out by the processor-compiled architecture and determining other portions of the service that include business logic to be carried out by scripted architecture; organizing the portions of the service and the other portions of the service according to a corresponding business process pattern in the plurality of business process patterns; and executing the service, the execution including generating a function call to each portion of the service that includes business logic to be carried out by the processor-compiled architecture and generating a service call to the service by retrieving and executing at least one code portion from the script repository to replace processor-compiled functions, in one or more of the portions of the service, with scripted business logic.
