# Storage frameworks With Langstack storage frameworks, users can create entity databases to store data. ## Database The Database section is used to create entities that can store structured data. ### Entity database * Users can create entities with fields as the basic building blocks. * An entity can store data in simple data types, e.g., strings, numerical, DateTime, GUID, boolean, or complex data types that can store records for other entities. * Entities can have one-to-one or one-to-many relationships with other entities. * Moreover, users have the option to create triggers that define data to be restructured based on record creation, update, or deletion. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
