Mashup is a new application development approach that allows
users to aggregate multiple services to create a service
for a new purpose. Even if the Mashup approach opens new
and broader opportunities for data/service consumers, the
development process still requires the users to know not only
how to write code using programming languages, but also
how to use the different Web APIs from different services.
In order to solve this problem, there is increasing effort put
into developing tools which are designed to support users
with little programming knowledge in Mashup applications
development. The objective of this study is to analyze the
richnesses and weaknesses of the Mashup tools with respect
to the data integration aspect.
