The objective of this paper is to present the first results concerning the mapping and implementation of the Fuzzy Semantic model (FSM) as a Fuzzy object-relational database model (FuzzORM). This solution permits to take advantages of both relational and object-oriented databases. The object-relationaldatabase management system PostgreSQL has been used for the implementation of the FuzzORM.

We have been designing and implementing an object-relational multimedia database. A new data model was first developed, which represents various types of media entities, and temporal/logical relationships among these entities. Thereafter, a three-layer object-relationaldatabase infrastructure was proposed in our project, in order to support the proposed data model. In this paper, we concentrate on the search and query mechanisms designated for our database infrastructure. In particular, we discuss a new query language, which is developed as a multimedia extension of SQL3. This query language provides a greater expressive power, not only on simple/complex media entities, but also on various relationships among different entities. Consequently, it supports both content-based and structure-based queries. We are currently implementing the query language in our object-relational multimedia database prototype system based on the Illustar. The fundamental structure of our query language as well as main features of object Manager and Query Manager of our prototype system, are also presented in the paper.

Modern interactive multimedia services, such as the video-on-demand (VoD), electronic library, and etc. tend to involve large-scale media archives of audio records, video clips, image banks, and text documents. Thus, these services impose many challenges on designing and implementing new generation database systems. In this paper, we first introduce a new multimedia data model, which could accommodate sophisticated media types, as well as complex relationships among different media entities. Thereafter, an object-relationaldatabase infrastructure is proposed, to support applications of the data model developed in our project. The infrastructure is designated both as a framework for designing and implementing multimedia databases, and as a reference model to compare and evaluate different database systems. Features of the proposed infrastructure, as well as its implementation into a prototype multimedia database system, are also discussed in the paper.
