Simple odds calculator for football events.

Football results from some (mostly European) leagues are stored in a PostgreSQL database (odds.sql). A program written in C++ accesses it with the libpqxx library. A number of algorithms can be used to process those results.

At this point it's all very basic and the odds calculated are based on very simple statistical analysis.

PostgreSQL:
sudo apt install postgresql postgresql-contrib
sudo systemctl enable postgresql
sudo systemctl start postgresql
sudo systemctl status postgresql
sudo chown postgres:postgres /home/yourname/odds/odds.sql
sudo -i -u postgres
createdb odds
psql -d odds -f /home/yourname/odds/odds.sql
