Peters, Randal J., Szafron, Duane, Ozsu, M. Tamer
Technical report TR92-14. Object-oriented computing is influencing many areas of computer science including software engineering, user interfaces, operating systems, programming languages and database systems. The appeal of object-orientation is attributed to its higher levels of abstraction for...

Li, John, Ozsu, M. Tamer, Szafron, Duane
Technical report TR96-12. Modeling moving objects has become a topic of increasing interest in the area of video databases. Two key aspects of such modeling are object spatial and temporal relationships. In this paper we introduce an innovative way to represent the trajectory of a single...

Goralwalla, Iqbal, Ozsu, M. Tamer, Leontiev, Yuri, Szafron, Duane
Technical report TR96-03. Most of the work in modeling time in information systems has concentrated on issues such as support for historical information and providing query facilities to manipulate such information. In doing so, some simplistic view of the underling nature of time has been...

1995
Ozsu, M. Tamer, Goralwalla, Iqbal, Szafron, Duane, Leontiev, Yuri
Technical report TR95-13. In this work, we present a uniform behavioral temporal object model which includes a rich and extensible set of types and behaviors to support various notions of time. Our temporal model supports the continuous and discrete domains of time. It also supports various...

Peters, Randal J., Ozsu, M. Tamer, Szafron, Duane, Lipka, Anna
Technical report TR93-01. The establishment of a formal object model provides a theoretical foundation to investigate other objectbase features such as query processing. In this report, we present an extensible uniform behavioral object query model for the TIGUKAT(*) object management system. ...

1994
Ozsu, M. Tamer, Tansel, Abdullah, Vittal, Chiradeep
Technical report TR94-16. We describe the design of a multimedia database for a distributed news-on-demand multimedia information system. News-on-demand is an application that utilizes broadband network services to deliver news articles to subscribers in the form of multimedia documents. ...

1997
Ozsu, M. Tamer, Li, John, Szafron, Duane
Technical report TR97-01. Declarative query languages are an important feature of database management systems and have played an important role in their success. As database management technology enters the multimedia information system domain, the availability of query languages for multimedia...

1994
Goralwalla, Iqbal, Ozsu, M. Tamer, Tansel, Abdullah
Technical report TR94-15. In this paper we describe an implementation of a temporal relational database management system based on attribute timestamping. For this purpose we modify an existing software which supports set-valued attributes. The algebraic language of the system includes...

Ozsu, M. Tamer, Li, John, Szafron, Duane
Technical report TR96-06. Video modeling has become a topic of increasing interest in the area of multimedia research. One of the key aspects in the video medium is spatial relationships. In this paper we propose a spatial representation, based on the temporal interval algebra, for specifying...

1998
Ozsu, M. Tamer, Szafron, Duane, Leontiev, Yuri
Technical report TR98-02. In this paper we present a model that supports a clean separation between the concepts of interface, implementation, and representation. We present several problems that are difficult to solve in the absence of such separation and describe how the proposed model can be...
