A multidatabase system based on OMG's distributed object management architecture and named Middle East Technical University (METU) INteroperable Database management system (MIND) is presented. MIND employs a dynamic query optimizer. After a query is decomposed, the global subsequeries are sent to the involved Local Database Agent (LDA) objects. The optimization process starts after the first partial result from a LDA object becomes available. For optimizing the intersite operations among these partial results, a statistical inferencing mechanism is used. Intersite operations are performed by Query Processor (QP) objects. There could be as many QP objects running in parallel as necessary.


Performing and analyzing non-formal inspections of entity relationship diagram (ERD)
ÇAĞILTAY, NERGİZ; TOKDEMİR, GÜL; Kilic, Ozkan; Topalli, Damla (Elsevier BV, 2013-08-01)
Designing and understanding of diagrammatic representations is a critical issue for the success of software projects because diagrams in this field provide a collection of related information with various perceptual signs and they help software engineers to understand operational systems at different levels of information system development process. Entity relationship diagram (ERD) is one of the main diagrammatic representations of a conceptual data model that reflects users' data requirements in a databas...
Testing embedded software: A survey of the literature
Garousi, Vahid; Felderer, Michael; Karapicak, Cagri Murat; Yilmaz, Ugur (Elsevier BV, 2018-12-01)
Context Embedded systems have overwhelming penetration around the world. Innovations are increasingly triggered by software embedded in automotive, transportation, medical-equipment, communication, energy, and many other types of systems. To test embedded software in an effective and efficient manner, a large number of test techniques, approaches, tools and frameworks have been proposed by both practitioners and researchers in the last several decades.
Graphical user interface (GUI) testing: Systematic mapping and repository
Banerjee, Ishan; Nguyen, Bao; Garousi, Vahid; Memon, Atif (Elsevier BV, 2013-10-01)
Context: GUI testing is system testing of a software that has a graphical-user interface (GUI) front-end. Because system testing entails that the entire software system, including the user interface, be tested as a whole, during GUI testing, test cases-modeled as sequences of user input events-are developed and executed on the software by exercising the GUI's widgets (e.g., text boxes and clickable buttons). More than 230 articles have appeared in the area of GUI testing since 1991.
Metamodeling of Reference Software Architecture and Automatic Code Generation
Turhan, Nafiye Kubra; Oğuztüzün, Mehmet Halit S. (2016-12-02)
Architectures of all application software that are developed by Sea Defense Systems Software Team in ASELSAN are created based on a predefined reference software architecture. In order to facilitate the process of transition from the software architectural design, which is created in conformance with the reference software architecture, to implementation a model driven software development approach is put forth. In this approach, based on a metamodel for the predefined reference software architecture, a dom...
A monolithic approach to automated composition of semantic web services with the Event Calculus
Okutan, Cagla; Çiçekli, Fehime Nihan (Elsevier BV, 2010-07-01)
In this paper, a web service composition and execution framework is presented for semantically -annotated web services. A monolithic approach to automated web service composition and execution problem is chosen, which provides some benefits by separating composition and execution phases. An AI planning method using a logical formalism, namely Abductive Event Calculus, is chosen for the composition phase. This formalism allows one to generate a narrative of actions and temporal orderings using abductive plan...
