Author: Inza Khan

Databricks is a powerful platform that offers a practical solution for handling and analyzing various data types. Databricks is used to efficiently manage structured, semi-structured, and unstructured data, drawing insights from transaction records, sensor data, social media feedback, and weather information.

Types of Data in Retail

• Structured Data

Structured data forms the foundation of retail analytics, including information such as sales transactions, customer details, and product inventory. Typically stored in formats like CSV or Parquet, this data provides an organized view of business operations.

• Semi-Structured Data

Semi-structured data introduces complexity and is often found in sources like customer reviews stored in JSON format. Extracting valuable information from such data requires specific handling techniques.

• Unstructured Data

Unstructured data, including images of products or text data, poses unique challenges. However, tapping into this resource can reveal insights that significantly impact retail strategies.
