A method for information service identification during service modeling of a service oriented architecture (SOA) architected computing system includes loading a business process defined by different business services in memory of a service modeling tool executing in a host computing platform. The method further includes identifying different information elements directed for access by the business services and determining a set of information transactions for the identified different information elements. The method yet further includes generalizing the set of information transactions into a candidate list of information services. The method even yet further includes selecting from amongst the candidate list a selection of information services for incorporation into the business process. Finally, the method includes refining the business services of the business process to invoke the selection of information services to access the identified different information elements.
