摘要：In the history of software development, there is a haven of different methodologies, approaches, and tools that have been designed to capture the expectations of customers and transfer them into requirements for information systems understandable by programmers. However, reality shows that the percentage of failures in development of information systems in terms of time, money, and functionality is not decreasing. This paper describes creation of a principle for and development of a domain-specific web site modeling language in order to make interactive dialogue during the very beginning of web site development process to match the expectations of both the customer and supplier. We have developed a tool to implement all the possibilities offered by language. The web site modeling tool has a corresponding component to each general function of the language. The web site model can be simulated within the tool and serve as a prototype for the desired web site in reality. Prototyping approach eliminates barriers between business and information technology people, leading to common understanding of web site goals and success in delivery and implementation. For a more practical view on the issue, the example of the State Revenue Service of the Republic of Latvia web site is examined in this paper.
