Traction has been a multi-revision development platform to be geared towards organizations and non-profit groups to maintain their membership base, and perform administrative tasks that historically were done via paper, spreadsheets, or other process requiring manual data-entry or duplicate entry.  Prior versions have been utilized by multiple Clients I have worked with over the years, and the current platform uses a more standardized code-base with room for custom functions instead of custom builds for each site.  Supported by a LAMP back-end.
