1. Goals :

This master thesis mainly addresses Information Visualization issues. It consists of being able to implement a visualization framework that enables users to visualize large-scale geo-referenced business flows (e.g. business products) and to provide the capacity to have business phenomenon, such as mid and long term flow tendencies to be efficiently „visually“ extracted for later interpretation.

2. Context (constraints)

- It is required to have the whole framework to be composed of a set of independent and maintainable modules. A 3-Tier architecture (client-server-database) is required, but the initial implementation release will be embedded into a stand-alone application for testing and validation purposes.

- Maximize information retrieval efficiency through visualization under a minimum cost of „user-friendliness“and ergonomicity.

- Allow maximum interaction between the user and the visualization.

- Keep universality in mind, in terms of reusability when addressing any kind of given business geo-referenced flows.

3. The business and the users

We expressively focus on business having their main activity based on flows. Flows are omnipresents, in any kind of business, from little shops to high-scale multinationals. Business flows can be categorized into, for example, items moved from one place to another, communication between two or more entities, value transfer between financial places, and so on.
Defining the typical user that has to stand behind such application is a critical issue; a rigorous analysis of all user aspects has to be done, starting at what business he is spezialized in, what kind of information he might need to resolve his problems, until human specific perception characteristics (such as understanding what perception channels are mostly to be addressed and how we could reach maximum cognition).
