A view is an interactive map that lets you display, explore, query and analyze geographic data. A view defines the geographic data that will be used and how it will be displayed, but it doesn’t contain the geographic data files themselves. Instead, a view references these source data files.
A view is also a collection of themes. A theme represents a distinct set of geographic features in a particular geographic data source. Each theme points to a data source somewhere on your system. The data can be on a local disk or on a disk on the network. Many themes can be derived from the same data source, but an individual theme can only reference a single data source.
