1. A method for validating executable data for interactions among a plurality of process artifacts at design time, said method comprising: creating a data context based on the plurality of process artifacts, said data context including interaction rules among the plurality of process artifacts, said included interaction rules defining sequences and interactions among the plurality of process artifacts; associating executable data with the plurality of process artifacts from a data source to the created data context based on the included interaction rules; selecting a subset of the interaction rules corresponding to at least one of the plurality of process artifacts; and validating the associated executable data when the associated executable data is in accordance with the selected subset of the interaction rules.
