Internet information services are developed everywhere. Such services include content generation and functionality support that have to be modeled in a consistent way. Here, we show how concepts of conceptual modeling can be used for systematic development of Internet sites. We give an introduction into our methodology of modeling Internet applications resulting in the Cottbus Internet site development language (SiteLang). The language has an operational semantics based on entity-relationship structuring and abstract state machines. It allows specification of entire Web sites, i.e., of structuring, behavior, information support, and of the interaction and story space. The methodology supports applications in different environments, e.g., Internet Web sites, WAP technology, or TV channels.

Technical Issues

Current web site development is still dominated by technical issues. In order to enable efficient communication between developers and to provide a stable foundation for adopting new technologies, conceptual modeling of web sites is essential. Based on the state-of-the-art of conceptual modeling as implemented in current CASE environments, this paper tries to identify the “essence” of a web site and proposes an adequate conceptual model. The model is intended to capture not only hierarchical document structure and hypertext semantics, but also dynamic page generation from databases and various approaches to explicit and implicit navigation. It becomes evident that web sites can be regarded as supersets of traditional information systems, thereby requiring conceptual modeling to include various additional features. The proposed model comprises several classes of information objects, various types of associations, design rules, and quality checks. For illustration purposes, the model is applied to an existing web site. Current web site development tools are analyzed with regard to the extent to which conceptual web site modeling is supported.

Current web site development is still dominated by technical issues. In order to enable efficient communication between developers and to provide a stable foundation for adopting new technologies, web sites should be derived from conceptual models. Based on the state-of-the-art of conceptual modeling as implemented in current CASE environments as well as web site development tools, the “essence” of a web site is identified, and an adequate conceptual meta model is proposed. Appropriate web site models are intended to capture not only hierarchical document structure and hypertext semantics, but also dynamical page generation from databases as well as explicit and implicit navigation. It becomes evident that web sites can be regarded as supersets of traditional information systems, thereby requiring conceptual modeling to include various additional features. The proposed meta model comprises several classes of information objects, various types of associations, design rules, and quality checks. For illustration purposes, the model is applied to an existing web site. Commercial web site development tools are analyzed with regard to the extent to which they support conceptual web site modeling.

he report explores and analyzes the application of the most popular programming languages from different organizations: GitHub; Stackoverflow; the TIOBE's Community index. The main client technologies: HTML; CSS; JavaScript; Typescript are presented and analysed. Features are characterized and the advantages and the disadvantages of the server technologies are described: Java; PHP; Python; Ruby. The application areas for web site development technologies have been defined. The creation of a quality web site is a complex and complicated process, but by observing some guidelines and recommendations in the work process can help to select the tools and the technologies in its design and development.

In order to represent spatio-temporal data, many conceptual models have been designed and a part of them have been implemented. This chapter describes an approach of the conceptual modeling of spatio-temporal data, called 3SST. Also, the spatio-temporal conceptual and relational data models obtained by following the proposed phases are presented. The 3SST data model is obtained by following three steps: the construction of an entity-relationship spatio-temporal model, the specification of the domain model and the design of a class diagram which includes the objects characteristic to a spatiotemporal application and other needed elements. The relational model of the 3SST conceptual model is the implementation of the conceptual 3SST data model on a relational database platform. Both models are characterized by generality in representing spatial, temporal and spatio-temporal data. The spatial objects can be represented as points or objects with shape and the evolution of the spatio-temporal objects can be implemented as discrete or continuous in time, on time instants or time intervals. More than that, different types of spatial, temporal, spatio-temporal and event-based queries can be performed on represented data. Therefore, the proposed 3SST relational model can be considered the core of a spatio-temporal data model.

Oriented Approach

Modeling techniques play an important role in the development of database applications. Well-known entity-relationship modeling and its extensions have become a widely-accepted approach for relational database conceptual design. An object-oriented approach has brought a new view of conceptual modeling. A class as a fundamental concept of the object-oriented approach encapsulates both data and behavior, whereas traditional relational databases are able to store only data. In the early 1990s, the difference between the relational and object-oriented (OO) technologies, which were, and are still used together to build complex software systems, was labeled the object-relational impedance mismatch (Ambler, 2003). The object-oriented approach and the need of new application areas to store complex data have greatly influenced database technology since that time. Besides appearance of object-oriented database systems, which fully implement objectoriented paradigm in a database environment (Catell et al., 2003), traditional relational database management systems become object-relational (Stonebraker & Brown, 1999). The most recent versions of the SQL standard, SQL: 1999 (Melton & Simon (2001) and SQL: 2003 (Eisenberg et al., 2004), introduced object-relational features to the standard and leading database producers have already released packages which incorporate them.

Recently the notorious Distributed Denial of Service (DDoS) attacks made people aware of the importance of providing available data and services securely to users. A DDoS attack is characterized by an explicit attempt from an attacker to prevent legitimate users of a service from using the desired resource (CERT, 2006). For example, in February 2000, many Web sites such as Yahoo, Amazon.com, eBuy, CNN.com, Buy. com, ZDNet, E*Trade, and Excite.com were all subject to total or regional outages by DDoS attacks. In 2002, a massive DDoS attack briefly interrupted Web traffic on nine of the 13 DNS “root” servers that control the Internet (Naraine, 2002). In 2004, a number of DDoS attacks assaulted the credit card processor Authorize. net, the Web infrastructure provider Akamai Systems, the interactive advertising company DoubleClick (left that company’s servers temporarily unable to deliver ads to thousands of popular Web sites), and many online gambling sites (Arnfield, 2004). Nowadays, Internet applications face serious security problems caused by DDoS attacks. For example, according to CERT/CC Statistics 1998-2005 (CERT, 2006), computer-based vulnerabilities reported have increased exponentially since 1998. Effective approaches to defeat DDoS attacks are desperately demanded (Cisco, 2001; Gibson, 2002).

The Village

This chapter reports on a study investigating a community Web site project operating in a UK village community. The aim of the study is to determine the impacts the online business directory component of this community Web site is having on the small businesses in the village, including consideration of the benefits they are deriving from their participation in the directory, the problems they have encountered through their participation, and the effects their involvement is having on their wider Internet adoption strategy and decisions. The findings highlight the value of community Web sites for small businesses, both for those that have already adopted various Internet applications into their operations, as well as for non-adopters of the Internet. It is suggested that existing discussions of small business approaches to Internet adoption might usefully be extended to incorporate the role of community Web sites.
