Signals can be sent from one data view to another when they have a field in common. They are sent by clicking on a link in a tabular data representation or clicking on a selectable region of a graphical representation. A data view can have any number of child data views that it sends signals to. In the case of data coming from a relational database, where there is a SQL query that corresponds to the data view, the signal is typically rendered as some type of constraint in a WHERE clause in SQL. The concept is not limited to RDBS databases but can be executed in the application when querying another webservice or NoSQL database. This signaling allows a user to drill down on a complex set of data. Data views can be displayed as multiple panes in a single browser window or spread out across multiple browser windows to make use of whatever screen capacity is available. | Signals can be sent from one data view to another when they have a field in common.

A collection of connected data views is displayed below. The first view in the collection, "Site Crashes" can send signals to the two child views "Site Related Crashes" and "Site Crash URL Summary". The signal sent/received is displayed in the middle control panel above the table display. This allows a user to analyze relation ships between these three different datatypes within a single browser window. | |||
