2.2 Exploratory Visualization

A Viewsheet provides a visualization of data provided by a Data Worksheet, query, data model, or database table.

A Data Worksheet is a graphically developed complex query, using mashup to manipulate and combine data from multiple sources. See Data Mashup for more information.

A query is a specific request for data from a database, or other source. You can create a query graphically with the Query Wizard, or by entering a desired SQL string. See Independent Query in Data Modeling for more information.

A data model is an abstract representation of a database schema, mapping database tables and columns into easy-to-understand entities and attributes. See Semantic Layer – Data Model in Data Modeling for more information.

The Viewsheet extracts the data relationships that you develop in the Data Worksheet, query, model, or table and presents them in an intuitive and interactive visual interface. You can use the Viewsheet to navigate any inherent hierarchy in the data, and you can add new information for “what-if” analysis and other advanced applications.

The example Viewsheet below is included in the default installation.
