Tryton is a three-tier high-level general purpose computer application platform on top of which is built an Enterprise resource planning (ERP) business solution through a set of Tryton modules. The three-tiers architecture consists of the Tryton client, the Tryton server and the Database management system (mainly PostgreSQL).
The client and the server applications are written in Python, the client use GTK+ as graphical toolkit. Both are available on Linux, OS X. The kernel provides the technical foundations needed by the most business applications. However it is not linked to any particular field hence constituting a general purpose framework:
- Data persistence: ensured by accessor objects called Models, they allow easy creation, migration and access to records.
- User Management: the kernel comes with the base features of user management: user groups, access rules by models and records, etc.
- Workflow Engine: allows to activate a workflow on any business model.
- Report Engine: the report engine is based on relatorio that uses ODT files as templates and generate ODT or PDF reports.
- Internationalisation: Tryton is available in English, French, German, Spanish,and Italian. New translations can be added directly from the client interface.
- Historical data: data historization may be enabled on any business model allowing for example to get the list of all the past value of the cost price of any product. It also allows to dynamically access historized record at any time in the past: for instance the customer information on each open invoice will be the ones of the day the invoice was opened.
- Support for DAV protocols: WebDAV, CalDAV, and CardDAV. This allow out-of-the-box document management and synchronizations of calendars and contacts.
- Support for XML-RPC and JSON-RPC protocols.
- Database independence is allowed since the 1.2 series and is used in the 1.4 series for the SQLite backend.
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.
The platform, along with the official modules, are Free Software, licensed under the GPLv3.
