In this paper we construct a Star Join Schema and show how this schema can be created using the basic tools delivered with SQL Server 7.0. Major objectives are to keep the operational database unchanged so that data loading can be done without disturbing the business logic of the operational database. The operational database is an expanded version of the Pubs database [Sol96].

A prototype database is a model of a database which exhibits the desired properties, in terms of its schema and/or data values, of an operational database. Database prototyping has been proposed as a technique to support the database design process in particular, and the whole data-intensive application development process in general (e.g. requirements elicitation, software testing, experimenta...

Polyinstantiation has generated a great deal of controversy lately. Some have argued that polyinstantiation and integrity are fundamentally incompatible, and have proposed alternatives to polyinstantiation. Others have argued about the correct de nition of polyinstantiation and its operational semantics. In this paper we provide a fresh analysis of the basic problem that we are trying to solve,...

Operational reporting differs from informational reporting in that its scope is on day-to-day operations and thus requires data on the detail of individual transactions. It is often not desirable to maintain data on such detailed level in the data warehouse, due to both exploding size of the warehouse and the update frequency required for operational reports. Using an ODS as the source for oper...

WindSat was launched in 2003 and is the first satellite-borne fully polarimetric microwave radiometer (Gaiser et al. 2004). This is an early report indicating the potential benefit of polarimetric microwave observations from this instrument. Initial studies examining the impact of WindSat polarimetric microwave observations when assimilated into a version of the National Centers for Environment...

We sketch a logic-based framework in which computation consists of performing actions to generate a sequence of states, with the purpose of making a set of reactive rules in the logical form antecedents  consequents all true. The antecedents of the rules are conjunctions of past or present conditions and events, and the consequents of the rules are disjunctions of conjunctions of future condit...

For a decade, NATO nations, both on their own and within NATO groups have performed studies in the field of Twodimensional Inverse Synthetic Aperture Radar (2D-ISAR) and High Resolution Radar (HRR) Range Profiles. During that work high-quality radar imagery data of aircraft has become available through measurement campaigns. It was shown that the acquisition of a sufficiently large and represen...

In Dung’s abstract argumentation, arguments are either acceptable or unacceptable, given a chosen notion of acceptability. This gives a coarse way to compare arguments. In this paper, we propose a counting approach for a more fine-gained assessment to arguments by counting the number of their respective attackers and defenders based on argument graph and argument game. An argument is more accep...

Recently researchers have tried to apply ontology to the product information domain. From a practical point of view, a key problem to streamline this trend is how to make a product ontology database operational. Technical solutions should consider the characteristics that a pragmatic product ontology database contains; first, the database size is quite huge, and second, ontological manipulation...
