这需要很长的答案。我没有重复其他人在我面前说得更好更详细的话，而是将您链接到一些相关页面。我建议仔细看看它们。也许遵循一些额外的链接。维基百科总是一个好的开始。如果您在浏览链接后仍然对其中一种模式有任何疑问，请随时返回 SO 并再次提问。但是，如果这样做，请尝试缩小范围。最好问多个问题并专注于特定方面，而不是期望人们为您写一篇文章。

Object Relational Mapper

Object-relational mapping (ORM, O/RM, and O/R mapping) in computer software is a programming technique for converting data between incompatible type systems in relational databases and object-oriented programming languages.

Data Access Object

Use a Data Access Object (DAO) to abstract and encapsulate all access to the data source. The DAO manages the connection with the data source to obtain and store data.

DataMapper

A layer of Mappers (473) that moves data between objects and a database while keeping them independent of each other and the mapper itself.

Active Record

An object that wraps a row in a database table or view, encapsulates the database access, and adds domain logic on that data.

Table Data Gateway

An object that acts as a Gateway (466) to a database table. One instance handles all the rows in the table.
