# 5. Tools and dependencies installation

## 5.1. PostGreSQL and PostGIS

OpenLog - QGIS Plugin uses XplorDb python library in background. Xplordb depends on PostgreSQL, we recommend PostgreSQL version 14 and PostGIS version 3.

Warning

make sure, if you have multiple versions of PostgreSQL installed at once on your machine, to use the right network port (one port per version).

You will find installation instructions for your operating system on the dedicated documentation page.

Once PostgreSQL is installed, install PostGIS by following the installation instructions for your operating system.

Warning

Regular users are expected to connect to a remote xplordb database with appropriate credentials (provided by database administrators).

## 5.2. Microsoft SQL Server driver

OpenLog - QGIS Plugin can connect to Geotic database. To enable Geotic database support, you must install the Microsoft SQL Server driver.

Here are the installation instructions for Linux and for Windows.

Warning

Regular users are expected to connect to a remote Geotic database with appropriate credentials (provided by database administrators).
