The company's business intelligence (BI) environment today is a "Patchwork" of technology that has accumulated for a variety of reasons over a long period: many kinds of general-purpose database (DBMS) software, a collection of different servers and end-user application relying on different database and commumcation standards. Users have approach to content and applications they need through role-based workspace created in BI portal. According to Eckerson& Howson, 2005, they find queries, reporting and analytical tools too complex or time-consuming to use. They spend too much time looking for the right report among hundreds, or get lost in endless series of drill-downs and dimension lists. They think that rather than empower users, BI portals overwhelm them. Concept maps as knowledge visualization tools enable users to create one's own tailored individual workspace and provide the developers with useful information about the learning routes and performance of the knowledge workers. We investigate possibilities of applying concept mapping as a new approach to BI portal development.
