# Asset Tracking

One unique feature of mrViewer is its built-in asset tracking system. With it, every image or movie file that any person in your facility views will be recorded into a generic database and it will be sorted by show, sequence and shot.

## Setting up the Database

For mrViewer to save your images in a database, it is necessary for you to specify the database connection as well as prepare a compatible database for mrViewer.

The database server can be any machine in your facility and not the local machine where mrViewer runs on, but all other machines need to be able to access it through a TCP/IP connection. You can also set up different servers for different cluster of machines, to alleviate the load on large facilities.

Film Aura recommends using a Linux server for your database due to their reliability and best network throughput.

Currently, mrViewer supports the PostgreSQL database by default which is the most comprehensive free and open source database. Other database drivers may be added later (note that distribution of such drivers is often not possible for GPL only databases like MySQL due to licensing restrictions).
