Data Modelling and Management
Context
Problem
Information visualization application development requires balancing issues of data management, visual mappings, computer graphics, and interaction. Determining the right separation of concerns has serious consequences for the complexity, extensibility, and reusability of software architectures. The Reference Model pattern provides a general template for structuring visualization applications that separates data models, visual models, views, and interactive controls.
Forces
Solution
Separate data and visual models to enable multiple visualizations of a data source, separate visual models from displays to enable multiple views of a visualization, and use modular controllers to handle user input in a flexible and reusable fashion.
Examples
The Reference Model pattern has been widely used and advocated. Both Chi et al’s data state model [1] and Card et al’s infovis reference model [2] prescribe the use of this pattern. In their exploration of design choices for architecting visualizations, Tang et al. [3] also discuss the importance of separating data and visual models. Finally, numerous software frameworks adopt this template of application structure, including Advizor [4], Improvise [5], Polaris [6], [7], prefuse [8], and SAS/JMP [9].
