This Reference Design has been setup to illustrate the use of SVN DBLib in Altium Designer.

Setting up the system for SVN Subversion
Version Control System are tools to manage file revisions and Subversion needs to be installed prior to use SVN Database Libraries. Compiled packages of Subversion can be found freely over the internet http://subversion.tigris.org . When Subversion is installed, the version control feature in Altium Designer needs to be enabled by selecting the SVN - Subversion option and clicking the Auto Detect Subversion button in the Version Control ?General page of the Preferences dialog (DXP ?Preferences). Additional options are available in the Version Control ?SVN Libraries page of the Preferences dialog. A working folder for checked out files can be defined and the interval of repository cache files can be set.

Installing and Editing SVN DBLib
All SVN DBLib settings are centralised in one SVN DBLib file and configurable through the SVN Database Library editor by opening the SVNDBLib file - Linking parts parameters and database fields, and setting Symbols and Footprints folders can be done in this editor.

Setting up the system for SVN Subversion
The parts on this schematic have been linked to a SVN Database Library located in the Examples\Reference Designs\SVN DBLib directory of this installation. In this example, a Microsoft Access database has been used to create the library components and a SVN repository has been created to store and keep control of the files revisions. While the Symbols and Footprints are stored in a repository, it is possible to check out the Schematic and PCB libraries directly from the Libraries panel for editing - Selecting the Edit Symbol and Edit Footprint commands when right mouse clicking a component or a Footprint model will check out the corresponding library file into a working directory. The SVN DBLib working directory is set in the Version Control ?SVN Libraries page of the Preferences dialog (DXP ?Preferences).

Like other libraries types, SVN DBLib can be added to the Libraries Panel by clicking the Libraries button in this panel and installing SVNDBLib files in the Installed page of the Available Libraries dialog. Install the Examples\Reference Designs\SVN DBLib\Altium Design Library.SVNDbLib library.

When a Libraries are edited, the history and revisions of the files are displayed in the Storage Manager panel. Files can be committed and revisions can be physically compared using the right mouse click commands in this panel.
