Knowage is the open source business analytics suite that combines traditional data and big data sources into valuable and meaningful information. It merges the innovation coming from the community with the experience and practices of enterprise-level solutions.

Knowage suite is composed of several modules, each one conceived for a specific analytical domain. They can be used individually as complete solution for a certain task, or combined with one another to ensure full coverage of user’ requirements, allowing to build a tailored product.

Knowage suite is available on two versions. The Community Edition, with the whole set of analytical capabilities, entirely free under an open source licence, is part of the software stack managed by FIWARE as SpagoBI always did.

Knowage is the successor of SpagoBI and SpagoBI users are recommended to upgrade to Knowage
