1. What is Orm? ORMObject Relational ing, That is, object relationship ing. Its implementation idea is to map the table data in the relational database to an object and present it as an object, so that developers can convert operations on the database to operations on these objects. Therefore, it aims to facilitate developers to operate databases with an object-oriented approach. 2.What isHibernate There are many names for hibernate, such as tools,

1 Preface After a period of writing, I finally came up with a stable version, during which I considered a variety of solutions and secretly learned the works of the great gods in the garden. There are already many ORM frameworks. Why should we implement one by ourselves? My reason is that you can add specific code to the orm when encountering special requirements. For example, perform basic data verificatio

There are many MongoDB client products, all of which have the quality to put into the production environment. The MongoDB community also calls them drivers. In general, each programming language has its own drivers that cover all the popular programming languages, and some are not very popular progra

Object Relational ing (ORM) is a technology designed to solve the mismatch between objects and relational databases. To put it simply, Orm automatically persists the objects in Java programs to relational databases by using metadata describing the ing between objects and databases. In essence, data is converted from one form to another. This also implies additional execution overhead. However, if

Object Relational Mapping (relational Mapping, or ORM) is a technique to solve the mismatch between object-oriented and relational databases.
