Insights is an add-on for OBIEE providing a customisable UI framework that allows you to build front end web applications that interface with the OBI back end.
Specifically, there's a visualisation builder and dashboard viewer that has been built using this framework and provides many UI features not present in the standard application.
To deploy the application please follow the installation guide. Technical information can be found in the wiki for this project.
Note that Insights is only compatible with IE11, Chrome browsers and with OBIEE 11.1.1.9 and higher. Specific compatibility can be found in the technical guide.
