Combining computing and/or computing applications into surroundings, instead of having computers as discrete object is the aim of pervasive computing. Applications must adjust their behavior to every change in surroundings. Adopting involves proper capturing, maintaining and reasoning of context. This paper proposes effective representation of context in a hierarchical form and storing of context data in an object relational database than an ordinary database. Semantic of the context is managed by Ontology and Context data is handled by object relational database. These two modeling elements are associated to each other by semantics relations built in the ontology. The separation of modeling elements loads only relevant context data into the reasoned, therefore improving the performance of the reasoning process.
