For working with very large datasets, a data management system is required. For the DisC┼Ź project, we have decided to use Time Intelligence Solutions - [TIS] by XIMES. TIS is as system that can handle very large datasets and is specifically designed to work with time-oriented data. It is a web-based application that runs under ASP.NET and can be accessed by a web browser.

Data sets are called nodes in the TIS data structure. Nodes can be based on other nodes and modified by operators. The interaction of nodes and operators can be used to build complex arithmetic units. The Multi-Scale implementation is a graphics operator which takes a well-defined type of node and produces the Multi-Scale visualization off the contained data.
