Recent statistics illustrate that the penetration of mobile devices in everyday use has reached (and in some cases even surpassed) the penetration of fixed communication devices (ITU, 2004). As a consequence, use of mobile devices for accessing data information also increases, assisted by the rapid development of new technologies especially designed to support multimedia communication. Within the next years, thirdgeneration (3G) wireless services will proliferate, offering multimedia capabilities such as streaming video (BERGINSIGHT, 2005; Raghu, Ramesh, & Whinston, 2002; UMTS forum, 2005). All of these, combined with the establishment of Internet and portal technology as the standard way for information exchange, entertainment, and communication, have created a new scenery that is characterized by access to data “anywhere,” “anytime,” and by “anyone” (or “any means”). Design issues concerning the particularities of access devices, communication technologies, and volume of information exchanged are very important in the provision of mobile portal services (Microsoft, 2006). In this article, we address the issue of providing portal services to users with portable devices such as personal digital assistants (PDAs) or smartphones. We propose a reference architecture for providing mobile portal services, based on the distribution of information between the portal servers and the user devices.","PeriodicalId":349521,"journal":{"name":"Encyclopedia of Portal Technologies and Applications","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127544589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Candan","doi":"10.4018/978-1-59140-989-2.CH090","DOIUrl":"https://doi.org/10.4018/978-1-59140-989-2.CH090","url":null,"abstract":"Web portal applications that dynamically generate results in response to user requests are more popular than ever. Such portal applications usually consist of a business logic component and a very large database, or databases that hold the portal’s content. Despite efforts to speed up response generation, ever-rising user demand means that replication of a portal’s logic and database will be needed at some point as other methods to keep up with demand (faster databases and content caching for example) have limits. This article explains issues surrounding the replication of a single full-scale database-driven portal application. In addition to the issues of replicating a single, unsophisticated application, it also anticipates a future in which portal applications offer multiple levels of service to users, and large application service providers (ASPs) host and replicate many portal applications on networks of servers. An ASP must replicate complex portal applications in order to satisfy user demand while minimizing operating costs. ASPs will need mature tools for making replication decisions and deploying and otherwise managing their replication system. To that end, this article highlights two prototype software packages, ACDN and DATE/DASIM, that address some aspects of replica management by ASPs. Using the two prototypes as a starting point and recalling single portal replication issues, a set of features for a mature ASP replication management systems are proposed.","PeriodicalId":349521,"journal":{"name":"Encyclopedia of Portal Technologies and Applications","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127180910","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, the integration of business processes, automation of daily tasks, and data integration contribute to cut down costs and accelerate business operations. However, Web portal development and maintenance imposes many challenges to developers, such as how to provide personalization features to users (organizations and individuals), how to control access from different users, how to integrate and present data from different sources, and how to maintain the content of the Web portal. To overcome these problems, many Web portal development technologies, standards, and tools were created over the last decade to facilitate the construction, operation, and maintenance of Web portals. These tools offer a simple way to build a Web portal by automating some part of the complex code (concurrency, persistency, security) and also by offering APIs and wizards that facilitate development. Considering the types of users and services provided, portals can be categorized into four main categories (Bellas, 2004; Wege, 2002). The following categories of portals are not mutually exclusive, and hybrid portals that combine different aspects of the categories can exist:","PeriodicalId":349521,"journal":{"name":"Encyclopedia of Portal Technologies and Applications","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128473513","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"A Comprehensive Methodology for Campus Portal Development","authors":"Tharitpong Fuangvut, H. Hasan","doi":"10.4018/978-1-59140-989-2.CH029","DOIUrl":"https://doi.org/10.4018/978-1-59140-989-2.CH029","url":null,"abstract":"A campus portal is an exciting recent phenomenon forming part of the new generation of online services for all stakeholders in institutions of higher education. Conceptually, the general notion of a portal should be to be distinguished from that of other Web-based applications and the traditional Intranet of the institution. The literature review in the first phase of this research indicates that the major distinguishing characteristics of a campus portal are (1) personalisation, by which end-users are only able to access information and online services pertinent to their activities, and (2) customisation, by which end-users are able to select their preferred information channels and optional online services. The major objective of this research is to propose a development methodology specifically suitable for campus portal projects. While there are many accepted development methodologies for traditional and Web-based information systems, no clear body of knowledge on the development of campus portals has yet been recognised. Additionally, as this is a new area, the definitions, terms, concepts, and important issues agreed to by academic researchers and practitioners are still evolving. This research, therefore, needs to clarify and identify some important issues regarding campus portals and their development, prior to composing the development methodology. In the second and third phases of the research, two studies were carried out, a preliminary study and a case study. These generated more understanding of the issues and extended the body of knowledge on campus portals, especially concerning their development. The preliminary study explored and investigated the online services and campus portals of 40 higher education institutions’ sites in Australia, New Zealand, the USA, the UK, and Canada. The findings of the preliminary study show that there are no standard patterns in the function of personalisation and customisation in campus portals. A set of research questions were then put forward to drive further investigation into design and implementation issues regarding the personalisation and customisation functions of campus portals. The case study was conducted in an Australian university among the major stakeholder groups, namely, the development team and the end-users (students and academic staff). For the study of the development team, interviews were used to gather information on their current practices and their vision for the future direction of the campus portal. Students were the primary focus of the end-user study, from which data was collected using a survey to build up usage patterns of their online activities. In addition, a group of academic staff was interviewed to obtain data from their perspective to identify and clarify some important issues. In the final phase of the research, the review of existing development methodologies continued filtering them through a set of identified criteria based on the findings of the two studies.","PeriodicalId":349521,"journal":{"name":"Encyclopedia of Portal Technologies and Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132624917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
