Purpose

This project was developed with the help of Ecotope, Inc. It containes seperate modular functionalities that, when combined, can extract, transfrom, and load data from incoming sensors. The main goal was to rewrite the existing R pipeline code with Python making the codebase more readable. In addition to that, scalability was taken into account during this project since this codebase will be used to create pipelines for different sites in the future.

Architecture

extract.py

• loading data from a local file system
• extracting NOAA weather data from a FTP server

transform.py

• cleaning the data
  • rounding
  • removing outliers
  • renaming columns
  • filling missing values
• calculating dervived COP (coefficient of performance) values
• agreggating the data

load.py

• establishing a connection to the database
• loading pandas dataframe into a table in the database

config.ini

• database
  • user: username for host database connection
  • password: password for host database connection
  • host: name of host
  • database: name of database
• minute
  • table_name: name of table to be created in the mySQL database containing minute-by-minute data
• hour
  • table_name: name of table to be created in the mySQL database containing hour-by-hour data
• day
  • table_name: name of table to be created in the mySQL database containing day-by-day data
• input
  • directory: diretory of the folder containing the input files listed below
  • site_info: name of the site information csv
  • 410a_info: name of the 410a information csv
  • superheat_info: name of the superheat infomation csv
• output
  • directory: diretory of the folder where any pipeline output should be written to
• data
  • directory: diretory of the folder from which extract loads the raw sensor data

Unit Testing

To run Unit tests, run the following command in the terminal in the corresponding directory:

python -m pytest
