# LightningDataModule - Comprehensive Guide
## Overview
A LightningDataModule is a reusable, shareable class that encapsulates all data processing steps in PyTorch Lightning. It solves the problem of scattered data preparation logic by standardizing how datasets are managed and shared across projects.
## Core Problem It Solves
In traditional PyTorch workflows, data handling is fragmented across multiple files, making it difficult to answer questions like:
- "What splits did you use?"
- "What transforms were applied?"
- "How was the data prepared?"
DataModules centralize this information f
