System architecture design (shown in Fig. 3.), which previously consisted of knowledge representation databases, development application, and consulting application for Web and W AP interfaces, will be expanded by using SMS application. This SMS application will provide a proper access to the data stored in database, accordingly SMS based consultation is possible to be built. The SMS application utilizes request-response communication concept in order to provide consulting application based on the knowledge base stored in database. Thus, this SMS application would be a particular interface for an ES consultation service.
