openapc-olap is a small OLAP Server based on cubes. It offers a fast and efficient way of querying the OpenAPC data and also works as backend for the OpenAPC treemaps server.

Installation (requires a working PostgreSQL installation):

clone or download/unzip
cd openapc-olap
virtualenv venv (Create a python virtual environment)
source venv/bin/activate
pip install -r requirements.txt
python assets_generator.py db_settings (Generates a credentials file for the database)
sudo -u postgres psql -f setup.sql -v pw="'secret'" (Set up a database with roles and schema. Change the 'pw' parameter to something more sophisticated and copy the value to the 'pass' field in db_settings.ini, without any quotes.)
python assets_generator.py model (Generates a model file for the cubes server.)
python assets_generator.py tables (Create and populate the database tables. Requires the openapc core data file (apc_de.csv) and the offsetting file (offsetting.csv) to be present in the directory.)
python olap_server.py

These instructions will fire up a flask-based development server at localhost under port 3001 (Can be modified in cubes_server.py). For a long-term setup you should deploy a WSGI-based configuration.
