What is the role of the ORM framework in Python?
ORM, or Object-Relational Mapping, is a programming technique that maps object models to relational databases in order to manipulate databases through programming languages.
The purpose of ORM frameworks is as follows:
- Simplify database operations: ORM framework allows developers to operate databases in an object-oriented way, eliminating the need to write complex SQL statements, making the code more concise and readable.
- Increase development efficiency: ORM frameworks offer commonly used database operations methods and functions, such as CRUD, allowing developers to directly use these methods without having to write repetitive code, thereby improving development efficiency.
- The platform independence of databases: ORM frameworks can hide the differences between different databases, allowing developers to switch between different database systems without having to modify a lot of code.
- ORM frameworks typically offer functionality for database migration and version management, making it easy to upgrade and maintain databases.
- Mapping between objects and relationships: ORM frameworks map tables in relational databases to objects, allowing developers to manipulate objects to perform operations on the database, which reduces the complexity of development and maintenance.
In general, ORM frameworks simplify the complexity of database operations, increasing development efficiency and allowing developers to focus more on implementing the business logic without having to worry about the details of the underlying database.
