GNU Health/The Demo database
Introduction to the Demo Database
GNU Health default installation comes with no data. It's interesting, for academic and training purposes to have some demo data that exemplifies concepts and improves the learning curve.
The demo database is an ongoing project and it will be adapting to the each new GNU Health version. The clinical history will also grow with time.
For consistency sake, it's important to have the main characters information constant (family members name, birth dates and place, health centers, family doctors etc.). The information and characters are fictitious and we should try to make it valid for different cultures.

Online Demo Database
We have a community server available in the Internet so you can connect and try the latest GNU Health. This is probably the simplest way to check out GNU Health for the first time.
To use the GNU Health Demo Database, please proceed as follows:
1. Download and install the Tryton client application, according to your operating system:
- GNU/Linux, FreeBSD or other *NIX
- MacOS X
- Please note that the version of the Tryton client must match the version of the Tryton server. Otherwise you will not be able to connect to the community server ("Network Error: Connection refused!"). So if you have already installed the Tryton client, please verify the version number before continuing. Currently, the community server runs on Tryton 3.4.
2. Set the correct tabs position as described in "Setting the Tryton client Tabs position for GNU Health"
3. Connect to the GNU Health Demo Database using the following information:
Local Demo Database
This method should give the most up-to-date demo database with the fewer issues in the future.
First, as gnuhealth user, we download the newest demo database (2.6.4) and unzip it
$ wget http://health.gnu.org/downloads/postgres_dumps/gnuhealth-2.6.4-demo.sql.gz $ gunzip gnuhealth-2.6.4-demo.sql.gz
Second, we create an empty database to import the demo database into
$ psql -d template1 -c "create database gnuhealth_demo"
Third, we import the database
$ psql gnuhealth_demo < gnuhealth-2.6.4-demo.sql 
Now enter the database through Tryton client (as non-gnuhealth user)
- Database: gnuhealth_demo
- Username: admin
- Password: gnusolidario
There is a user "admin_es" that uses the Spanish language.
Installation Using Proteus Demo Script
The Proteus demo script is deprecated and won't be used in version 2.8 . Please use the demo database postgres dump
We use the proteus engine to install the demo database.
First we need to install proteus in your local environment
$ pip install --user proteus
Alternatively, and if you're using any Debian GNU/Linux system, you can also install proteus from a repository.
$ apt-get install tryton-proteus
Warning, do not install proteus using pip and then apt-get as well. Most likely difference version of proteus will be installed and the demo database installation will fail.
Now, look for the demo directory. You can run the script from anywhere, but make sure your tryton libraries are in the python search path. This is important, specially if you use the manual installation.
$ export PYTHONPATH="<PLACE_OF_YOUR_TRYTON_SERVER_DIRECTORY>"
So, for example, if you installed the GNU Health sever with the standard method, then your variable declaration for PYTHONPATH for Tryton 3.2.3 would be something like :
$ export PYTHONPATH="/home/gnuhealth/gnuhealth/tryton/server/trytond-3.2.3/"
Next, run the script :
$ cd <demo_directory> $ python health_demo_server.py
So, for example, if you installed the GNU Health sever with the standard method, the demo directory would ~/gnuhealth-2.6.4/scripts/demo (or whatever version number yours is) and you use:
$ cd ~/gnuhealth-2.6.4/scripts/demo $ python health_demo_server.py
This script will create a new database called gnuhealth_demo with the demo information. Be patient, it can take some time.

- Optionally 1>/tmp/log 2>/tmp/err may be added at the end of the line. For large databases and not so large computers, it could accelerate the load, while providing some clues just in case.
