These features distinguish DEVise from other visualization environments:
- Visual query interface: Visualizations constructed with one
set of data may be saved and applied to other input data.
- Data larger than memory are efficiently handled.
- Mapping from data to graphics at record level. (e.g., you can
control the color or shape of individual records.)
- Ability to query data records used to represent graphics.
- Flexible layout mechanisms within windows. It helps user group data
together for comparison, or put the aside when not needed.
- Linked X, Y, or X and Y axes.
- Cursor helps compare the relationship between different views
of the data.
- record based input data.
- Direct input of ASCII files.
- integer, float, and date data types.

For a detailed description of DEVise:
Michael Cheng, Miron Livny, and Raghu
Ramakrishnan. ``What's next? sequence queries.'' In Proceedings of the
International Conference on the Management of Data (COMAD),
is complementary to DEVise in that it is designed to query record based
sequenced data. The output of the queries may be visualized with DEVise.
