Currently, the development of IT such as the development of components and web-based services have emerged as an effective way to build a complex system of enterprise-scale information and providing enterprise application integration. However, there are still many problems that need to be addressed before the engineering service-oriented software (SOSE) becomes the leading paradigm and is widely accepted for business development and integration of information systems. Some of those perspectives include: concept-based services, modeling and documentation, service discovery and composition, service-oriented architecture, model-driven development of service-oriented applications, security and service-orientation in mobile settings.
