In this paper, the authors present the development of learning object ontology for SQL contents that are designed according to the computer science curriculum standards of the ACM/IEEE Computer Society 2013. The learning object schema was designed by using the SCORM and the ontology approach. The learning objects can be used as the knowledge base of intelligent tutoring system. The major characteristics of them are smaller learning units. These learning units facilitate to retrieve, share and reuse. In addition, it helps to define the different learning strategies of intelligent tutoring system in order to enhance the performance of system.
