End User Mashup Programming Environments

Short Description
There is believe that creating of web sites is the task that can be done only by processionals. Thing are developing pretty fast and new generation of online visual tools enable end users to create interactive web pages with dynamically changing content in visual programming environments. We analyzed and compared several most popular tools that allow creation a mashup type of web applications by integrating content from several online sources. Comparison identified trends and technologies will help in decision making during design phase of new interactive multimedia services by concept creator, business developers and software developers.

Mashup are new sort of interactive WEB applications that combine simple data that exposed by already existing services. The result of that combination delivers new values to the end user and can be viewed as new type of service as such (Altinel et al, 2007).
There are different ways of building up mashup site. There is a hard way – that is to use some programming language for data extraction from 3rd party services on the server side and programmatically combining data together. One has to have software development skills and access to running web server in order to achieve that goal.
Alternative approach would be to use visual tools that would enable achieving the same result but in much simpler way (Maximilien et al., 2007; Spoerri, 2007). That is a way that does not require knowledge of the programming languages, data formats and hosting environment. Environments that allow end user to create mashups tools are analyzed and compared in our paper. Design for the end user programming systems has take into account that users have neither time nor inclination to study programming languages or hidden aspect of the development system. Such end-user programming environments rely on metaphors that are easy to grasp by non professional coders e.g. spreadsheets, flow of linked processing blocks, visual selection of GUI actions and binding them together.
