FastVersion

FastVersion is a Qgis plugin for data versioning in a Postgis database.
This plugin provides data versioning to tables with geometry stored in postgis.
It allows to create, changes and eliminate versions, and within each version , to insert, modify and eliminate elements.
It is possible carry out the processes of “post” from one version to another, with conflict resolution functionality.
The system uses algorithms and data structures so that information is not duplicated each time a version is created.

We recommend downloading it from the Qgis app.

If downloaded from sourceforge, it must be unzipped in \.qgis2\python\plugins
