The Medical Device System (often abbreviated to MDS) is the data base (see [[MDS Database]] for information specific to the database tables) and graphical user interface used to house medical device program related data such as companies, company contacts, applications for authorization, lists of devices, and more. It is also the source of the data for the Medical Devices Active Licence Listing (MDALL), the outwardly visible database of licensed devices.

The MDS is divided up into sections; this related mostly to the function, but there is substantial communication between the sections (e.g., while the Company section maintains information about companies, other sections like Applications or Incidents will refer to the company entries.)

==History==

==History==

Prior to April 2018, the MDS was run on HP PowerHouse, and this interface and system was rather dated and due to the departure of staff knowledgeable about the language, impossible to update and maintain. The system had been labeled a legacy system that required replacement. In April 2018, the new interface was launched, an HTML5 web-based interface that was more modern and allowed continued development.

The system had been labeled a legacy system that required replacement. In April 2018, the new interface was launched, an HTML5 web-based interface that was more modern and allowed continued development. Querying of the system was performed with Cognos Impromptu, and as there was no ability to edit the framework that supported these searches it was difficult to develop new reports. With the upgrade to the system it became possible to add new functionality; some of the new improvements include the addition of a pdf and XML reader for industry problem reports, the addition of a post-market tracking module, and rapid changes to add new COVID-19 interim order authorizations. 

The system runs on a Oracle database - it was on version 11g for many years and was updated in 2021 to Oracle 19c.

In the old PowerHouse system, each section of the user interface was accessed by numbers, and some fields still have these references in the HTML version or in documentation (e.g., the numbers before the sub-sections on the device screens refer to the field numbers in the old MDS system).
