数据库常用的数据模型包括关系模型、面向对象模型和分布式模型。

1. 关系模型(Relational Model) - Relational Model is a computationally simple model used to relation to a relational set of multiple elements, including data collections, tables, and tree.

2. 面向对象模型(Object-Oriented Model) - Object-Oriented Model is a simple data-collection model used to relation to nested objects, including data elements, tables, and tree.

3. 分布式模型(Distributed Model) - Distributed Model is a computationally efficient model used to represent a series of data integers to machine transactions, including data collections, tables, and tree.

以上这些数据模型的主要区别是它们具有不同的数据结构和存储方式,因此在应用上需要根据具体的需求选择合适的模型。
