Web services composition with redundancy consideration

Web services composition is a process of creating a new Web service from a set of available Web services. Semi-dynamic Web services composition in Service Oriented Architecture (SOA) consists of designing composition plan by service provider, and automation of Web service discovery and selection at runtime. This research paper describes redundant-free Web services composition in order to reduce execution time and overall cost of the composition process and also improve efficiency of the composition method. To fulfill the needs, this paper uses a linked list data structure called Composition List (CL) to select the ideal services. In addition, a hash table called Available Output Parameters (AOP) is used to find redundant Web services and reject them from Web services composition process.

Model Driven Web Engineering: A Systematic Mapping Study

Background: Model Driven Web Engineering (MDWE) is the application of the model driven paradigm to the domain of web software development, where it is particularly helpful because of the continuous evolution of Web technologies and platforms. Objective: In this paper, we prepare a survey of primary studies on MDWE to explore current work and identify needs for future research. Method: Systematic mapping study uses for finding the most relevant studies and classification. In this study, we found 289 papers and a classification scheme divided them depending on their research focus, contribution type and research type. Results: The papers of solution proposal (20%) research type are majority. The most focused areas of MDWE appear to be: Web Applicability (31%), Molding and Notation (19%), and Services and Oriented (18%). The majority of contributions are methods (33%). Moreover, this shows MDWE as a wide, new, and active area to publications. Conclusions: Whilst additional analysis is warranted within the MDWE scope, in literature, composition mechanisms have been thoroughly discoursed. Furthermore, we have witnessed that the recurrent recommendation for Validation Research, Solution Proposal and Philosophical Papers has been done through earlier analysis.

Analyzing Interaction Flow Modeling Language in Web Development Lifecycle

Two years ago, the Object Management Group (OMG) adopted a new standard method named Interaction Flow Modeling Language (IFML) for web engineering domain. IFML is designed to express the content, user interaction, and control behavior of the front end of applications. There are number lacks in web engineering methods, because each of them is defined to particular specifications, one of which is the open issue of supporting the whole lifecycle in process development. In this paper, we analyze IFML models in the process development lifecycle to show capability of the method used in the process development. We then make a comparison between IFML and other methods in lifecycle phases. Finally, we add IFML to the web engineering lifecycle’s map. It is anticipated that the result of this paper will be to become a guide for developers for using IFML in the development of new applications.

A Comparison of Navigation Model between UWE and WebML: Homepage Development Case Study

Web Engineering is a systematic approach for the development of web applications. In this area navigation model is defined as an important model in all the hypermedia and web engineering methods. Also homepage is one of the most important pages on the websites, because it is considered to be the key element that demonstrates the quality of websites. The web engineering methods still have weaknesses that are difficult for designers to design homepages content perfectly. In this paper we compare navigation model between UML-Based Web Engineering (UWE) and Web Modeling Language (WebML). The purpose of this paper is to find a quality in these methods for the homepages development, through designing navigation model in UWE and WebML, and comparing the elements of the navigation model. The result of this paper helps the designers to develop the homepages in order to solve of the weaknesss navigation model.

A New Adaptive Model for Web Engineering Methods to Develop Modern Web Applications

With the evolution of modern web applications, several web engineering methods proposed to develop web applications. The modern web applications are; Rich Internet Application (RIA), Semantic Web Application (SWA), Ubiquitous Web Applications (UWA), and Intelligent Web Applications (IWA), with each of them having new features. The problem is that current web engineering methods cannot support new features of modern web applications. However, some of them extended for new concern of web applications but have limited, meaning these methods have a lack of adaptability to support features from modern web applications. In an attempt to solve this gap, we have defined a new adaptive model for the web engineering methods that can support the new features of modern web applications. This model very efficient in the process development and will be to increase the usability of the methods.

Comparison between Web Engineering Methods to Develop Multi Web Applications

Web applications act as a source of strength for business growth over the internet and have become the backbone of the e-commerce. With the evolution of these type of applications, numerous features have been added to overcome the issues of complexities of the processes development web engineering methods. These methods are intended for specific purposes, and there has been some lack of the development of web applications, especially concerning the new types of web applications. The problem is that web engineering methods cannot support new features of web applications, furthermore no single method to support all types of web applications. In an attempt to solve this problem, a significant amount of work has been undertaken to improve or extend these methods to develop new types of web applications. In this paper, we make a comparison between web engineering methods (including IFML) to support the features of modern web applications. The result of our comparison will show the capability of the methods to support modern and multi web applications, and help the developers in the process development web applications.
