backend. * Built-in automatic migration mechanism: it allows updating the underlying database scheme without any human manipulation. Migration is ensured from series to series (releases inside the same series do not require migration). This automation is possible because the migration process is taken into account and tested continually within the development. * Advanced modularity: the modularity allows a layered approach of the business concepts along with flexibility, which speeds up custom developments. Being a framework, Tryton can be used as a platform for the development of various other solutions than just business ERPs. A very prominent example is GNU Health, a free Health and Hospital Information System based on Tryton.

Project management and governance

In contrast to their parent project and other open-source business software, the Tryton founders avoided creating a partner network, which tends to generate opposition and duality between the partners and the community of volunteers. They followed the PostgreSQL example where the project is driven by a federation of companies. As of August 2015, Tryton is supported by 17 of such companies, which are distributed globally as follows: France 3, Spain 3, Colombia 2, Germany, 2, Argentina 1, Australia 1, Belgium 1, Brazil 1, India 1, Mexico 1, Switzerland 1. As of December 2012, the project is backed by ''Tryton'', a
