Modelling and Implementing Macro Web Navigation Structures

From the three existing dimensions - content objects, navigation and presentation - of web pages, the navigation dimension is analysed. It consists of macro, meso and micro navigation. A conceptual approach to model and implement the macro navigation structure of web sites is presented. We start by enhancing a function decomposition diagram to model the macro navigation structure. The resulting graph is analysed and transformed to find its crucial components. In order to store these components in a database table, an appropriate entity-relationship model is developed. Afterwards we identify three navigation styles that can be produced from the underlying database and give the PHP source code for one of them. Finally, an example web page using our navigation styles is depicted. It is concluded that using our ideas may lead to reduced development time and avoids link errors in the process of creating the site navigation

Concpetual Design of WWW Based Information Systems

Today, companies and their information systems are facing a very dynamic and fast changing environment. Fast changing demands require varying information in varying places. Users must find relevant information in a fast and perspicuous way. Thus, information systems both have to be flexible and clearly structured to fulfill these requirements and be able to handle the increasing amount of information efficiently. WWW-based information systems provide flexibility as they separate content, layout and navigation. However, several conceptual shortcomings prevent the Web from being a more productive and efficient resource of information today. Several technical enhancements (e.g. the semantic web) have been made in order to solve these problems. However, a theoretically proved and easy to use modeling method for WWW-based information systems is still missing. Our modeling method allows modeling these information systems on a conceptual level by abstracting from technical details. By this, meaningful navigation structures can be achieved with great clarity. In this paper we will develop this method using a meta-model based approach

Semantic business process management: scaling up the management of business processes

Business Process Management (BPM) aims at supporting the whole life-cycle necessary to deploy and maintain business processes in organisations. Despite its success however, BPM suffers from a lack of automation that would support a smooth transition between the business world and the IT world. We argue that Semantic BPM, that is, the enhancement of BPM with Semantic Web Services technologies, provides further scalability to BPM by increasing the level of automation that can be achieved. We describe the particular SBPM approach developed within the SUPER project and we illustrate how it contributes to enhancing existing BPM solutions in order to achieve more flexible, dynamic and manageable business processes

Navigational Design of Web Information Systems - Framework Development and Case Study

As prior empirical and conceptual work indicates, success and usability of web information systems is subject to navigational design. Although web information systems are not a new phenomenon and were examined intensively in the past, holistic in-depth investigations of navigational issues seem to be arbitrary rather than theoretically and conceptually founded. In particular, we argue that we are lacking an appropriate description language serving as a shared conceptualization of our subject of research. We present a conceptual framework for describing and assessing web information systems and their navigational capabilities. Moreover, we provide some empirical evidence of its applicability by reporting on a case study that pays special regard to navigational design and usability improvement
