Dedale is a prototype of a constraint database for multidimensional data, conceived for spatio-temporal applications. It is implemented on top of BASIS, and uses a graphical user interface for querying purposes. Its main characteristics are (i) to offer a real abstraction of geometric data allowing the development of high level extensible query languages with a potential for optimization, while (ii) allowing the use of optimal computation techniques for spatial queries.
Currently Dedale was tested on Geographical applications, click here for more details.
