Let's imagine our company provides data services for local governments. The company does not own or generate data; its services are mainly based on aggregating data from external sources and providing them in a digested form. One of the services offered is based on weather data, and provides early alerts when weather forecasts extend certain configured parameters.
In this example, we will simulate services for Polish local government and use the following data sources:
- The third level of administrative boundaries of Poland
- OpenWeatherMap data services
The administrative boundaries simulate our own data source from which we will be generating weather alerts, while OpenWeatherMap is a weather data service provider.
Let's first prepare our company database. In order to do so, we first need to obtain the boundaries of the administrative divisions of Poland. The official data can be downloaded from http://www.codgik.gov.pl/index.php...
