Maintaining Web Applications by Translating Among Different RIA Technologies

As RIA (Rich Internet Application) technologieshave been widely used, the compatibility problem has arisen:they are hardly compatible with each other. To solve theproblem, we have proposed and implemented an automatic RIAtransformation system named Web-IR, which uses anXML-based intermediate representation with a Java-basedframework. As concrete examples, Web-IR currently supportsAjax, Flex, JavaFX, and OpenLaszlo as its input/output. Ourevaluations show that Web-IR can transform existing realapplications into other RIA technologies keeping almost thesame appearances. Finally, we conclude that Web-IR can solvethe problem sufficiently

Rendering real-time dashboards using a GraphQL-based UI Architecture

With the increase in the complexity of the systems being built and demand in the quality of service by the customers, developing and providing highly efficient real-time systems is one of the biggest challenges today for software enterprises. BluemixTM ─ IBM’s cloud offering implemented on Cloud Foundry, an open source “Platform as a Service” (PaaS), is an example of such a system. Currently, there are approx. 26 infrastructural services running in the background from where the data is fetched and is rendered on different dashboards of the system. However, the system suffers from performance issues. This thesis explores the performance improvements of the real-time dashboards by introducing our proposed GraphQL-based UI architecture which allows caching and asynchronous loading. The test results of this architecture’s implementation on the Bluemix Usage Dashboard show that the Real data renders 245% faster and the Switching Account 153% faster than the existing system

Ensuring software maintainability at software architecture level using architectural patterns

Software architecture is known to be an effective tool with regards to improving software quality attributes. Many quality attributes such as maintainability are architecture dependent, and as such, using an appropriate architecture is essential in providing a sound foundation for the development of highly maintainable software systems. An effective way to produce a well-built architecture is to utilize standard architectural patterns. Although the use of a particular architectural pattern cannot have a preserving effect on software maintainability, the mere conformance of a system to any architecture cannot guarantee the system’s high maintainability. The use of an inappropriate architecture can seriously undermine software maintainability at lower levels. In this article, the effect of standard architectural patterns on software maintainability quality attributes is investigated. We develop a quality model for maintainability quality attributes, which is later used to compare various standard architectural patterns. We finish by investigating two real-world experiences regarding the application of a particular pattern to two different existing architectures, exploring the effect of the change in architecture on maintainability quality attributes

Transforming Legacy Web Applications to the MVC Architecture

With the rapid changes that occur in the area of Web technologies, the porting and adaptation of existing Web applications into new platforms that take advantage of modern technologies has become an issue of increasing importance. This paper presents a reengineering framework whose target system is an architecture based on the Model-View-Controller (MVC) design pattern and enabled for the Java ™ 2 Platform, Enterprise Edition (J2EE). The proposed framework is mainly concerned with the decomposition of a legacy Web application by identifying software components to be transformed into Java objects such as JavaBeans, JavaServer Pages (JSP), and Java Servlet. 1
