In this paper, a review of some of the major ODBMSs (GemStone, O2, Objectivity/DB, ObjectStore and VERSANT) and Object-Relational DBMSs (Illustra, Odapter and UniSQL) is presented. The major architectural components are described and various features, such as support for relationships, schema evolution, etc. are also discussed. The discussion of each product concludes with a summary of its majo...

INTRODUCTION Application of computed tomography for monitoring intracranial stents is limited because of stent-related artifacts. Our purpose was to evaluate the effect of gemstone spectral imaging on the intracranial stent and stent lumen. MATERIALS AND METHODS In vitro, we scanned Enterprise stent phantom and a stent-cheese complex using the gemstone spectral imaging protocol. Follow-up gem...

For five centuries artisans have been cutting faceted gemstones, creating jewels that sparkle with internally reflected light, showing off the “fire” of the stones. Working with stones that are transparent or translucent, a cutter makes the most of the color of a stone through careful choice of the angles between facets, depending on the refractive index of the material. At the same time, gem p...

Active object-oriented concepts are especially useful in the area of nonstandard applications in order to express an event-driven and constraint-driven system environment [Chak90, Daya88b, Ahme92]. Several attempts have been made to integrate active concepts into object-oriented databases [Beer91, Daya88a, Diaz91, Gatz91, Geha91, Kim92, Mede91]. Current approaches to active objectoriented datab...
