What is the purpose of using the ORM framework in Django?

The ORM (Object-Relational Mapping) framework in Django is a tool designed to simplify database operations. It enables developers to interact with databases using Python code without the need to write SQL statements directly. The ORM framework maps database tables to Python objects, allowing developers to manipulate these objects to perform CRUD operations on the database.

ORM framework offers an object-oriented way to manage databases, where developers can define model classes to describe the structure and relationships of database tables. The framework will automatically generate database tables based on these model classes and provide a set of methods to operate on these tables. Developers can utilize the ORM framework to perform database queries, inserts, updates, deletions, etc., without having to directly write SQL statements.

The advantages of ORM framework include:

1. Streamlining database operations: Developers can utilize Python code instead of writing complex SQL statements, reducing the learning curve and cost of operation.
2. Improving development efficiency: ORM frameworks offer a range of methods and functions that reduce the amount of code needed for database operations, allowing developers to complete database-related tasks more quickly.
3. Independence of databases: ORM frameworks can support multiple types of databases, allowing developers to easily switch between different databases without needing to modify a lot of code.
4. Maintenance of database table structure: ORM framework can automatically generate database tables based on model classes and update the database table structure according to changes in model classes, simplifying the maintenance of database tables.

In summary, Django’s ORM framework simplifies and streamlines database operations, improving development efficiency and reducing the complexity of database operations.
