This paper presents a language and a system to construct a hypertextual view (a hyperview) of the content of a database. We first study different approaches to map database objects to hypertext components: tuple level mapping, tuple sets mapping, and associated tuples mapping. Then we present a declarative hyperview definition language which integrates these approaches. With this…

The messenger paradigm is an alternative to computer communication based on the exchange of programs called messengers which are afterwards executed, instead of messages that are interpreted. The communication by messenger paradigm can be used to implement both low level software such as communication protocols and high level software such as distributed applications. Using the…

An important problem that many large organizations face today concerns the support and evolution of their large (legacy) information systems. In this paper we present an approach for migrating large and interdependent legacy information systems to CORBA based platforms. Our approach allows continuous availability of the information systems, minimal manpower for the implementation and…

We use wehn-issued transactions data to assess the Treasury's current experiment with uniform auctions, suggesting a higher information release, which should reduce pre-auction uncertainty and the winner's curse. Under uniform auctions, wehn-issued volatility falls after the auction and again after the outcome announcement. The pattern is the opposite for discriminatory…

This paper describes three insolvency codes, those of the United Kingdom (UK), Germany, and the United States (US) and compares their efficiency against a number of benchmarks. These codes have been chosen because they cover a broad spectrum of debtor- and creditor-oriented insolvency procedures. The paper also compares the plans of distressed firms' reorganizations both within…

Many applications require the capability to define and manipulate a collection of related objects as a single unit. Object-oriented database models and systems usually provide the concept of composite object for that purpose. The concept of context that we propose here provides another, more general, way to view and manipulate collections of objects. We compare the two concepts both…
