A model-driven approach to develop high performance web applications

The evolution of web technologies in the last few years has contributed to the improvement of web applications, and with the appearance of AJAX and Web 2.0 technology, a new breed of applications for the Internet has emerged: widgets, gadgets and mashups are some examples of this trend. However, as web applications become more and more complex, development costs are increasing in an exponential rate, and we believe that considering a software engineering methodology in the development process of this type of applications, contributes to the solution of this problem. In order to solve this question, this paper proposes a model-driven architecture to support web application development from the design to the implementation model. With this aim, the following tasks have been performed: first a new profile extends UML with new concepts extracted from the web domain, then a new framework supports web application development by composing heterogeneous web elements, and finally, a transformation model generates web applications from the UML extension proposed. The main contribution of this work is a cost and complexity reduction due to the incorporation of a model-driven architecture into the web application development process, but other advantages that can be mentioned are a high performance degree achieved by a prefetching cache mechanism, and a high reusability, since web elements can be reused in different web applications.     

Byte code level cross-compilation for developing web applications

JavaScript provides the technological foundation of Web 2.0 applications. AJAX (Asynchronous JavaScript And XML) applications have received wide-spread attention as a new way to develop highly interactive web applications. Breaking with the complete-page-reload paradigm of traditional web applications, AJAX applications rival desktop applications in their look-and-feel. But AJAX places a high burden on a web developer requiring extensive JavaScript knowledge as well as other advanced client-side technologies. In this paper, we introduce a technique that allows a developer to implement an application in Java or any.NET language and then automatically cross-compile it to an AJAX-enabled web application.     

An empirical investigation into open source web applications’ implementation vulnerabilities

Current web applications have many inherent vulnerabilities; in fact, in 2008, over 63% of all documented vulnerabilities are for web applications. While many approaches have been proposed to address various web application vulnerability issues, there has not been a study to investigate whether these vulnerabilities share any common properties. In this paper, we use an approach similar to the Goal-Question-Metric approach to empirically investigate four questions regarding open source web applications vulnerabilities: What proportion of security vulnerabilities in web applications can be considered as implementation vulnerabilities? Are these vulnerabilities the result of interactions between web applications and external systems? What is the proportion of vulnerable lines of code within a web application? Are implementation vulnerabilities caused by implicit or explicit data flows? The results from the investigation show that implementation vulnerabilities dominate. They are caused through interactions between web applications and external systems. Furthermore, these vulnerabilities only contain explicit data flows, and are limited to relatively small sections of the source code.     

Web technologies for integration of applications in a training situation center environment

Up-to-date approaches to the integration of applications in a situation center (SC) environment are described. The role of web integration of applications in a SC is defined as set of certain web services interacting with each other within a unified SC environment. To find the most effective method of application interaction in a SC environment, qualitative assessment is carried out of application integrability. As a result the value of the integrability criterion is determined for particular applications. Fundamental advantages of introduction the web integration of applications in SC are defined and basic standards and specifications considered, on which web integration is based. Special attention is given to organization of a data system in a SC environment.     

Enabling the generation of web applications from mockups

Mockups are widely used to elicit and validate user requirements in web applications, and several intuitive tools have been developed in recent years, actively involving the end user in the requirements solicitation process. However, most current web development approaches and tools discard mockups after the information‐gathering process, abandoning the opportunity to exploit underlying information in them for autogenerating functional web applications. To overcome this limitation, we have devised a method for deriving the database schema and the logic of the web application from the information contained within mockups. In particular, the method gathers clues on how to organize the data and the control flow of the web application by analyzing the structure and relationships of the widgets in the mockup. Based on the proposed method, we have implemented a tool supporting the generation of web applications abiding by the model‐view‐controller architectural pattern. The tool has been evaluated by involving several end users in the development of web applications for different domains.
