An OTP application developed as a continuous lab classes project on Erlang and Elixir programming course.
The application provides server allowing to measure pollution levels from different measuring stations.
- Change comments from polish to english in polution module
- fix streams usage in pollution_data_stream module
- build hierarchy in src dir - group utils and training modules
- fix testing so they pass with simple
rebar3 eunitcommand
$ rebar3 compile
$ rebar3 shell
The stacktrace print during tests is caused by an intentional server crash
$ rebar3 test
The module contains structure of data - records station and measurement.
A single measurement station is represented as a map(station -> map(measurement -> value)).
The module contains also number of functions providing operations available on a monitor:
- adding a station
- adding a measurement value to a specific station
- removing a specific measurement
- getting a specific value depending on station and measurement parameters
- getting a mean of measurements of given type on a given station
- getting a daily mean from all stations
- getting a maximum value of given type and a station that has measured it
- getting a mean of measurements of given type on a given rectangular area
A client wrapper around previous module - creates more friendly API and guarantees basic app protection Not used anymore - replaced by PollutionGenServer
From the client perspective basicly identical funcionality as PollutionServer, but it implements gen_server behaviour and because of that it delivers better application protection.
Purely training modules - they import data from pollution.csv file, perform operations on it and measure the time of execution The Stream solution needs fixing.
