Data loaders are software components or utilities that facilitate the process of loading data into a system
or database. They are designed to handle large volumes of data, ensuring efficient and accurate data transfer.

In the context of [Generative AI](https://promptmetheus.com/resources/llm-knowledge-base/generative-ai) and machine learning models,
data loaders are used to feed data into the AI models during the training
process, often providing features like batching, shuffling, and parallel data loading to optimize the
training procedure.

In the context of [Prompt Engineering](https://promptmetheus.com/resources/llm-knowledge-base/prompt-engineering) tools and IDEs, data loaders are used to inject external data into a prompt, e.g. from a database, an API, or from the internet.
