What does odm mean?

ODM is the abbreviation of Object-Document Mapping, which means object-document mapping. It is a software design pattern used to establish mapping relationships between object databases and relational databases.

Object-Document Mapping (ODM) is a data mapping technology used to establish mapping relationships between object-oriented programming languages ​​and document databases. In short, ODM converts and maps data between object models and document databases.

In traditional relational databases, ORM (Object Relational Mapping) is used to implement mapping between objects and tables. In a document database environment, ODM is used to map objects and documents. Document databases typically store data in the form of documents, in formats such as JSON or XML.

ODM technology allows developers to use an object-oriented approach to operate document databases without directly dealing with the underlying document format and query language. It provides a convenient way to store, retrieve, and manipulate data in document databases while taking advantage of object-oriented programming such as inheritance, polymorphism, and associations.

In summary, ODM is a technology used for data mapping between object-oriented programming languages ​​​​and document databases, allowing developers to use object-oriented methods to operate data in document databases.
