Solving Web-based Applications Architectural Problems in the Cloud: The Way Forward

Highly-available and scalable software systems can be a complex and expensive proposition. Traditional scalable software architectures have not only needed to implement complex solutions to ensure high levels of reliability, but have also required an accurate forecast of traffic to provide a high level of customer service. This traditional software architecture is built around a common three-tier web application model that separates the architecture into presentation, business logic and database layers. This architecture has already been designed to scale out by adding additional hosts at these layers and has built-in performance, failover and availability features. Even with all these developments in architectural designs, some software still lacks in scalability, reliability and efficiency. This paper therefore examines the shortfalls of traditional software architectural problems with a view to addressing them using the cloud computing approach.

Ontology-Enhanced User Interfaces

Ontologies have been increasingly used in software systems in the past years. However, in many of those systems, the ontologies are hidden “under the hood”. While a lot of useful applications of ontologies on the database and business logic layer have been proposed, the employment of ontologies in user interfaces has been gaining comparatively little attention so far. For providing a deeper understanding of that field as well as assisting developers of ontology-enhanced user interfaces, the authors give an overview of such applications and introduce a schema for characterizing the requirements of ontology-enhanced user interfaces. With this article, a state of the art survey of approaches is presented along with promising research directions.

Chromhome: a rich internet application for accessing comparative chromosome homology maps.

BackgroundComparative genomics has become a significant research area in recent years, following the availability of a number of sequenced genomes. The comparison of genomes is of great importance in the analysis of functionally important genome regions. It can also be used to understand the phylogenetic relationships of species and the mechanisms leading to rearrangement of karyotypes during evolution. Many species have been studied at the cytogenetic level by cross species chromosome painting. With the large amount of such information, it has become vital to computerize the data and make them accessible worldwide. Chromhome is a comprehensive web application that is designed to provide cytogenetic comparisons among species and to fulfil this need.ResultsThe Chromhome application architecture is multi-tiered with an interactive client layer, business logic and database layers. Enterprise java platform with open source framework OpenLaszlo is used to implement the Rich Internet Chromhome Application. Cross species comparative mapping raw data are collected and the processed information is stored into MySQL Chromhome database. Chromhome Release 1.0 contains 109 homology maps from 51 species. The data cover species from 14 orders and 30 families. The homology map displays all the chromosomes of the compared species as one image, making comparisons among species easier. Inferred data also provides maps of homologous regions that could serve as a guideline for researchers involved in phylogenetic or evolution based studies.ConclusionChromhome provides a useful resource for comparative genomics, holding graphical homology maps of a wide range of species. It brings together cytogenetic data of many genomes under one roof. Inferred painting can often determine the chromosomal homologous regions between two species, if each has been compared with a common third species. Inferred painting greatly reduces the need to map entire genomes and helps focus only on relevant regions of the chromosomes of the species under study. Future releases of Chromhome will accommodate more species and their respective gene and BAC maps, in addition to chromosome painting data. Chromhome application provides a single-page interface (SPI) with desktop style layout, delivering a better and richer user experience.

WEB SERVICES INTERACTIONS: ANALYSIS, MODELING, AND MANAGEMENT

This paper discusses how interactions between Web services engaged in composition scenarios are analyzed, modeled, and finally managed. Interactions are primarily considered as a means for conveying messages of different natures between separate components, for instance, Web services. To achieve better coordination and hence, avoid conflicts between Web services, in this paper interactions are handled by two layers known as business logic and support. The business-logic layer is the host of two flows known as control and transactional, whereas the support layer is the host of two additional flows namely exception and message. On top of the proposed layers and flows, context and policies are used to oversee the progress of interactions between Web services and to constrain the behavior of these Web services, respectively.

Developing portals/portlets using Enterprise JavaBeans for Grid users

AbstractA Web‐based portal acting as a presentation layer to the Grid allows us to provide a transparent means of access to Grid resources. Our previous experiences in developing Grid portals have shown that there is a need to draw a clear high‐level picture of the architecture. This could be defined using the J2EE component‐oriented architecture, which enables a clear separation between the presentation, business logic and data layers. Additional benefits come with J2EE 1.4 making it possible to build up advanced service‐based Grid portals by exposing stateless session beans as Web services. In this paper, lessons learnt from our prototype portal/portlet development using Enterprise JavaBeans (EJB) are reported. Copyright © 2007 John Wiley & Sons, Ltd.

Improving efficiency in business-to-business information transfers: a Web-based solution in the beef sector

Internet usage is growing rapidly among agricultural producers and processors, but little attention has been paid to the advantages of agribusiness firms using the Internet as an information exchange with other firms, such as input suppliers. A case study of a beef processor using the Internet to deliver information to input suppliers is presented to illustrate possible information transfer efficiency gains. The prototype information delivery system is a three-tier, Web-based product consisting of data, business logic, and presentation layers. Compared to a traditional client–server design, the Web-based system is more easily scalable as system demand increases, more easily managed whenever software is updated, more flexible, less costly, and more reliable. An overview of the system's design is provided to facilitate information professionals developing a similar system, which is specific to their business model.
