MySQL and MariaDB support

July 17th, 2018

Today, we are excited to announce that the Orthanc project officially supports the highly popular MySQL and MariaDB databases through dedicated, free and open-source plugins! This new development expands the functional scope of Orthanc even more, as a large number of PACS administrators in hospitals are more familiar with these database engines than with PostgreSQL. This is a nice milestone, just 2 days before Orthanc celebrates its 6th birthday!

This development was triggered last year by Osimis, the commercial partner of Orthanc, that launched a crowdfunding campaign to this end. Because the goal of the campaign was not met at that time, an industrial user of Orthanc has fortunately decided to help Osimis by funding this development. We wish to warmly thank this great partner for its support!

Besides the "index" plugin that was the topic of the crowdfunding, a "blob storage area" plugin for MySQL and MariaDB has also been developed in order to store the DICOM files directly into an enterprise-ready database (a similar possibility already exists for PostgreSQL). Simultaneously, the PostgreSQL plugins have been rewritten almost from scratch in order to share as much C++ and SQL code as possible between all the database engines. Furthermore, the PostgreSQL plugins were optimized alongside, leading to their 2.2 release that was also released today. Thanks to this intricate refactoring, introducing support for new database engines will become a much more easier process (don't hesitate to get in touch with Osimis if you want to fund such a development ;-) ).

As always, all this code is shared as free and open-source software to the benefit of the worldwide community of medical imaging: Check out our download page! Note that the Windows installers now come bundled with all the MySQL and PostgreSQL plugins.
