Temporal Data Modeling and Reasoning for Information Systems
Temporal knowledge representation and reasoning is a major research field in Artificial
Intelligence, in Database Systems, and in Web and Semantic Web research. The ability to
model and process time and calendar data is essential for many applications like appointment
scheduling, planning, Web services, temporal and active database systems, adaptive
Web applications, and mobile computing applications. This article aims at three complementary
goals. First, to provide with a general background in temporal data modeling
and reasoning approaches. Second, to serve as an orientation guide for further specific
reading. Third, to point to new application fields and research perspectives on temporal
knowledge representation and reasoning in the Web and Semantic Web
A modeling approach for the development of process driven web applications
Complex web applications have been developed rapidly as to support complex process and transactional workflows involved in the web domain. Although there are numerous modeling concepts exist in web applications nowadays, new issues raises in modeling approach such as user interactions, interrelated process flow, navigational issues and graphical user interface concerns. In this paper, we present and discuss user interaction diagram, Unified Modeling Language (UML) notation and object-oriented approach for necessity in complex web applications. A proposed model called UEWDM (UML-Extensions Web Design Model) emphasize on the user interaction issues as well as the interrelated process, navigation and graphical user interface. The uniqueness of UEWDM is in the design pattern modeling approaches. At the end of the paper, future works of the design model will be explained and briefly summarized
Comparative analysis of interaction flow modeling language tools
Modeling approaches based on standards are of paramount importance in the field of front-end design for web and mobile applications. Problems are often encountered during the selection of tools for designing applications for developers and researchers, particularly applications that are related to time and cost in the market and academia. The Interaction Flow Modeling Language (IFML) is a recently standardized modeling language designed for managing the content expression, user interaction and behavior control of front-end applications. IFML brings several benefits to the development process of web and mobile front-end applications. Thus, several tools have been developed for the exploitation of technical artifacts offered by current specifications. In this study, we discuss the tools proposed for modeling IFML to provide a comparative analysis while considering various criteria. The result can be used as a basis of tool selection for specific aspects
Business integration models in the context of web services.
E-commerce development and applications have
been bringing the Internet to business and marketing
and reforming our current business styles and
processes. The rapid development of the Web, in
particular, the introduction of the semantic web and
web service technologies, enables business
processes, modeling and management to enter an
entirely new stage. Traditional web based business
data and transactions can now be analyzed,
extracted and modeled to discover new business
rules and to form new business strategies, let alone
mining the business data in order to classify
customers or products. In this paper, we investigate
and analyze the business integration models in the
context of web services using a micro-payment
system because a micro-payment system is
considered to be a service intensive activity, where
many payment tasks involve different forms of
services, such as payment method selection for
buyers, security support software, product price
comparison, etc. We will use the micro-payment case
to discuss and illustrate how the web services
approaches support and transform the business
process and integration model.
Developing BP-driven web application through the use of MDE techniques
Model driven engineering (MDE) is a suitable approach for performing the construction of software systems (in particular in the Web application domain). There are different types of Web applications depending on their purpose (i.e., document-centric, interactive, transactional, workflow/business process-based, collaborative, etc). This work focusses on business process-based Web applications in order to be able to understand business processes in a broad sense, from the lightweight business processes already addressed by existing proposals to long-running asynchronous processes. This work presents a MDE method for the construction of systems of this type. The method has been designed in two steps following the MDE principles. In the first step, the system is represented by means of models in a technology-independent manner. These models capture the different aspects of Web-based systems (these aspects refer to behaviour, structure, navigation, and presentation issues). In the second step, the model transformations (both model-to-
model and model-to-text) are applied in order to obtain the final system in terms of a specific technology. In addition, a set ofEclipse-based tools has been developed to provide automation in the application of the proposed method in order to validate the proposal.Torres Bosch, MV.; Giner Blasco, P.; Pelechano Ferragud, V.

MDA-based ATL transformation to generate MVC 2 web models
Development and maintenance of Web application is still a complex and
error-prone process. We need integrated techniques and tool support for
automated generation of Web systems and a ready prescription for easy
maintenance. The MDA approach proposes an architecture taking into account the
development and maintenance of large and complex software. In this paper, we
apply MDA approach for generating PSM from UML design to MVC 2Web
implementation. That is why we have developed two meta-models handling UML
class diagrams and MVC 2 Web applications, then we have to set up
transformation rules. These last are expressed in ATL language. To specify the
transformation rules (especially CRUD methods) we used a UML profiles. To
clearly illustrate the result generated by this transformation, we converted
the XMI file generated in an EMF (Eclipse Modeling Framework) model.Comment: International Journal of Computer Science & Information
