In service-oriented information systems, a methodology is needed to distinguish one service from another and to define classes of services. A DNA of services is proposed consisting of a service DNA sequence of five letters corresponding to a five-dimensional quadrant-based scale. Each type of service is assigned a DNA sequence. If two services have the same DNA sequence, then they are in the same service class. The methodology provides a basis for classifying services for service-oriented architecture and information systems.
