Using SQL to identify fraudulent credit card transactions.

IDENTIFYING SUSPICIOUS ACTIVITY USING SQL.

Fraud is everywhere these days—whether you are a small taco shop or a large international business. While there are emerging technologies that employ machine learning and artificial intelligence to detect fraud, many instances of fraud detection still require strong data analytics to find abnormal charges. I will apply SQL skills to analyze historical credit card transactions and consumption patterns in order to identify possible fraudulent transactions.

I will accomplish three main tasks:

Data Modeling: Define a database model to store the credit card transactions data and create a new PostgreSQL database using your model.

()

Data Engineering: Create a database schema on PostgreSQL and populate your database from the CSV files provided.

Data Analysis: Analyze the data to identify possible fraudulent transactions.
