review the literature of conservatism in financial reporting indicates the importance of conservatism in accounting profession. researchers have always tried to determine the degree and ways of conservatism in financial reporting and accounting, although this is not done easily, because there is not a direct measure of conservatism. however, conservatism has been one of the key principles in ac...

Knowledge bases are currently being investigated by database researchers in order to extend the expressiveness of the relational model to include deductive capabilities in the form of rules. The motivation behind this paper is to present a formalism which extends the relational approach to homogeneous distributed databases to the knowledge base paradigm. The basis of our formalism of distribute...

Voyage optimization is a technology to predict the ship performance in various sea states and current conditions, and based on the performance of the ship to assist ship masters in route selection. The targets of increasing energy efficiency and reducing Green House Gas (GHG) emission in the shipping industry can be achieved by voyage optimization. However, the practical and accurate prediction...

Initially, relational database is for both operational and decision support system, as the information society experiences exponential growth in the amount of data/information to be stored in a database, a line has been drown between transactional database and decision support database. Unlike traditional database, data warehouse aims to come from a number of preexisting databases (developed fr...

This project built a medical informatics data warehouse (MedInfo DDW) in an Oracle database to analyze medical information which has been collected through Baylor Family Medicine Clinic (FCM) Logician application. The MedInfo DDW used Star Schema with dimensional model, FCM database as operational data store (ODS); the data from on-line transaction processing (OLTP) were extracted and transferr...

CHRIS is an expert software tool to help in the design and rapid prototyping of information systems containing a database component. CHRIS involves an extended entity-relationship information model, the relational data model and a database management system. A prototype version of the tool, written in Prolog extended with a query-the-user facility, is fully operational. The prototype includes a...

By using this service interface and communicating with Map-Resolvers and Map-Servers, LISP Ingress Tunnel Routers and Egress Tunnel Routers are not dependent on the details of mapping database systems, which facilitates experimentation with different database designs. Since these devices implement the "edge" of the LISP infrastructure, connect directly to LISP-capable Internet end sites, and co...

It is very common that the large and multinational business organizations distribute their operational database systems over the wide area networks. The data integration from the distributed and highly autonomous operational database systems has to overcome many organizational and technical problems. Materialized view is the permanently stored relational table that contains integrated data from...
