DAE (Data Analysis Engine) is a framework that provides various tools for data analysis, which can assist the users in their decision making process. The tools exploit visualizations techniques; various visualizations may be generated for a set of data in order to allow users to browse among data and get the information of interest as well as discover new and possibly unexpected insights. DAE is quite general and can manage data in different domains. It supports several activities involved in the data analysis process, starting from data selection, performing various data transformations and presenting the analysis results. DAE aims at giving decision makers the possibility to directly analyze data with different tools.
