Aim of Project

Data Extraction

Data Cleaning and Transformation

Database Loading

Automation

Tools & Technologies

RapidAPI: This is used to extract real estate data.

Python: For data extraction, transformation, and loading (ETL process).

Postgres: A relational database for storing the property data.

Power BI: Data visualisation

Windows Task Scheduler / Cron: For scheduling periodic tasks to extract and load data.

GitHub: For version control and documentation. I got the real estate API from Realty Mole Property then I extracted and transformed via Python and loaded the transformed data into Postgress. Check link below to view the pipeline code, this solve Zipco Real Estate Agency problem as stated below

Below is the ERD from Schema in Postgres that the automated flow from the pipeline into Postgres

Data Modeling

Create a Star Schema: Fact Table: Central table containing metrics like property sales, area, bedrooms, etc. Dimension Tables: Reference tables for location, features, and sales details.

Schema Design: Location Dimension: Attributes like county, state, zipCode.

Features Dimension: Attributes like propertyType, zoning, features.

Sales Dimension: Attributes like sales_id, lastSalesDate, lastSalePrice etc

Fact Table: Links the dimensions table using their foreign keys

Below is the data modeling

I imported the data directly from Postgres to Power BI to building sales performance dashboard to show how much property was sold as at when and the location of each property sold and some other metrics were considered. Below is the dashboard

Task Scheduler: Open Task Scheduler. Create a new task, and set the trigger to run the Python ETL scripts & Power BI dashboard at a specified time (e.g., daily).

Set the action to run the Python script (python path_to_script.py) .& Power BI dashboard

I automated the refresh process using Task Schedular, this task will be run on a weekly basis to run the pipeline and also update the power Bi, so as to get the updated report on a weekly basis.
