Abstract
Bringing context into systems design has added a new dimension to modern technology. In service-centric and social-centric systems, the personalization of services to accommodate the preferences of each individual is essentially based on context information. Due to this importance, a significant amount of research work is being done on structuring and modeling contexts. However, no work has been done on storing these models using recent database technologies and techniques. Also, there is no reported work that considers a structure for context history, which is essential to maximize accessibility and scalability of context information in dynamic settings. Motivated by these issues, we have developed a general structure for storing context using three different database models. Additionally, we have compared the three models in terms of their performance and modeling ability. In this paper we present the data models for context, context history, and provide a summary of the experimental analysis conducted on them.
