In this paper we propose a set-oriented rule-based method deenition language for object-oriented databases. Most existing object-oriented database systems exploit a general purpose imperative object-oriented programming language as method deenition language. Because methods are written in a general-purpose imperative language, it is diicult to analyze their properties and to optimize them. Opti...

Deductive object-oriented databases are intended to integrate the deductive and object-oriented database techniques to combine the best of two approaches and to overcome their inherent shortcomings, with a number of deductive object-oriented database languages proposed. However, most of these languages are only structurally object-oriented. Important behaviorally object-oriented features such a...

The problem of finding the most appropriate, sophisticated or innovative approach, technology and method teaching English for specific purposes has always drawn specialists’ attention. Nowadays a promising graduate any educational institution is to be able establish professional communication not only in native language, but also foreign one. A military academy an exception. Peacekeeping operat...

Very well known problems such as the fragility problem, the AOP paradox, or the aspect interference problem threaten aspect oriented application in the modeling phase. In this work we explore FVS, a declarative visual language, as an aspect-oriented modeling language. Our language exhibits a very flexible and rich joinpoint model to leverage aspect-oriented application and is suitable for incre...

Abstract As a growing approach to assessment, learning-oriented assessment (LOA) has recently flourished position learning at the center of practices. It aims unify teaching, and learning. However, little is written known about its benefits, challenges, practices in English as foreign language (EFL) contexts. To shed light on these aspects, present study was bid unpack Iranian EFL teachers’ per...

Integrating concurrent and object-oriented programming has been an active research topic since the late 1980s. The majority of approaches have taken a sequential object-oriented language and made it concurrent. A few approaches have taken a concurrent language and made it object-oriented. The most important of this latter class is the Ada 95 language which is an extension to the object-based co...
