“…The richness of the features in RIAs can be analyzed into three main aspects: 1) the rich GUIs, enabled by the advancement of client-side development TTs, which allow building desktop applications like GUIs; 2) the rich communication model -commonly known as the asynchronous communication -which permits to communicate only the smaller and needful set of data, faster and also asynchronously; and 3) the enhanced user experience, enabled by the synergy of the aforementioned two features [1], [4], [14], [15].…”

“…As mentioned before, the smaller size of the data is the reason for the increment of the speed. Therefore, we propose to use the term "Delta-Communication" (DC) -as already had been used by Mesbah et al [4] -to denote the rich communication model of RIAs, which emphasizes the smaller size of the data communicated.…”

I. INTRODUCTIONRich Internet Applications (RIAs) are very complex Web based systems [1], [2]. RIAs are encompassed with various types of components, integrated in diverse ways, making the RIAs more complex systems [3]. Numerous Technologies and Techniques (TTs), frameworks, libraries, and tools had been introduced over the last decade for the development of these components of RIAs [4]. However, these TTs, frameworks, libraries, and tools do not improve the fundamental concepts in the core of the RIAs [2], and the complexity remains due to the lack of realization of the abstract architectural formalism of the RIAs. Moreover, these TTs may introduce new layers of complexity and learning curves into development. Therefore, in the terms of the complexity, the advancement of TTs and tools does not provide much assistance.Even though lots of tools had been introduced and many researches had been conducted in the domain of RIAs, still few researches have focused on the abstract fundamental concepts of the RIAs; and standard definitions for these concepts have still not been articulated [5]. Definitions of the concepts provide precise common understanding of the subject towards proper utilization of the concept. If we can realize the fundamental abstract (by the means of TTs independent) architectural elements of RIAs and their characteristics well enough and strongly define them, the complexity can be reduced; since the complexity encloses the difficulties in understanding the software systems [6].Our ongoing research intends to reduce the complexity of the RIAs by identifying the fundamental abstract architectural elements of RIAs, specifying their characteristics, and introducing terms and definitions for them; in the direction of introducing an abstract architectural style for RIAs. This paper focuses on the rich communication model of the RIAs, which can be seen as the power of the RIAs (This is further discussed in section III). This rich communication model has two communication modes according to the direction of the data transmitted: 1) data-pull and 2) data-push. In data-pull mode, the client requests and fetches data (or pulls data) from the server, based on the traditional request-response model. In data-push mode, the server-components push the data to the client-component(s) when needed, without receiving a request from the client. In this paper we focus only on the data-pull mode.This paper discusses the fundamental characteristics of the rich communication model of the RIAs, as identified through the literature survey and empirical evidence gained from a series of experiments; then proposes a definition, indicating the limitations of the general term "Asynchronous Communication", which is currently used to denote this rich communication model. Based on this definition, the paper also delivers a term and a definition for the simplest abstract technique, which can be implemented using this rich communication model; which is exploited in the popular technique named Asynchronous Javascript And Xml (AJAX) [7...

Bioinformatics applications are generally multi-server dependants and will have to communicate several information repositories to carry out any analyses. These applications remain computationally intensive and time consuming as they engage lots of data transfer. Hence they face a major bottleneck when ported as web applications. Browser based web applications normally feature the classical request-response approach. If the response becomes late, as it is expected to happen in the case of long running Bioinformatics programs, Apache will get tired and a request timeout error might occur. Alternate approaches like "Client-Pull" models that involve polling strategy with the unpredictable amount of page refreshes, only tend to intensify the network traffi c. Hence a technology that is intelligent enough to support the varied exhaustive Bioinformatics processes becomes highly essential. In this review, we propose how AJAX can afford a laconic framework within the Bioinformatics applications to completely reduce the page refresh nuisance and provide a better user experience.

“…The recent breed of Web 2.0 applications dubbed AJAX (Asynchronous JavaScript and XML) [7] is designed to have high user interactivity and low user-perceived latency [13].

AJAX applications are designed to have high user interactivity and low user-perceived latency. Real-time dynamic web data such as news headlines, stock tickers, and auction updates need to be propagated to the users as soon as possible. However, AJAX still suffers from the limitations of the Web's request/response architecture which prevents servers from pushing real-time dynamic web data. Such applications usually use a pull style to obtain the latest updates, where the client actively requests the changes based on a predefined interval. It is possible to overcome this limitation by adopting a push style of interaction where the server broadcasts data when a change occurs on the server side. Both these options have their own trade-offs. This paper explores the fundamental limits of browser-based applications and analyzes push solutions for AJAX technology. It also shows the results of an empirical study comparing push and pull.
