# Core DataFrames and Data Loading

This reference covers Vaex DataFrame basics, loading data from various sources, and understanding the DataFrame structure.

## DataFrame Fundamentals

A Vaex DataFrame is the central data structure for working with large tabular datasets. Unlike pandas, Vaex DataFrames:
- Use **lazy evaluation** - operations are not executed until needed
- Work **out-of-core** - data doesn't need to fit in RAM
- Support **virtual columns** - computed columns with no memory overhead
- Enable **billion-row-per-second** processing through optimized C++ backend
