STORM: structural and temporal object-oriented multimedia database system

Abstract

The STORM DBMS integrates structural and temporal aspects for building different presentations of multimedia objects (i.e. text, audio, image, video). We integrate structural operators (e.g. tuple, list, set) and temporal relationships (e.g. before, after, equal) for defining multimedia presentations. Temporal aspects are modeled through the notion of Temporal Shadow which incorporates free or bound durations and/or delays. Our approach provides sequential and parallel presentations synchronizing different objects. These presentations are themselves stored as database objects and can be derived automatically from the schema, updated and queried.
