Issues in developing objectoriented database systems for real-time applications

Database systems for real-time applications must satisfy timing constraints associated with transactions, in addition to maintaining data consistency. Recently, interests in object-oriented databases have been growing for non-traditional applications of database systems, and several real-time applications are being developed using an object-oriented paradigm. The object-oriented approach seems promising for developing complex real-time database applications. However, it is not clear whether object-oriented database systems would be superior than relational database systems for supporting real-time applications. In this paper, we address issues that must be investigated in order to design and develop an object-oriented database system for real-time applications. Also, we present a model that integrates features for scheduling real-time transactions with the traditional object-oriented database model. 1
