ORM stands for Object-Relational Mapping. It is a technique used in software development to convert data between relational databases and object-oriented programming languages like Python, Java,, Ruby…
The main purpose of ORM is to provide a higher-level, abstract API for accessing and manipulating databases that is more in line with the syntax and concepts of the programming language in use, instead of having to write raw SQL queries. This can simplify database access, make the code more readable, and reduce the risk of SQL injection attacks.
For example, instead of writing SQL statements to insert, update, or retrieve data from a database table, you can use an ORM library to interact with the database using objects and methods in your programming language.
Some popular ORM libraries for various programming languages include:
- Django ORM for Python
- Hibernate for Java
- Ruby on Rails Active Record for Ruby
- Entity Framework for .NET
- Laravel Eloquent for PHP
By using ORMs, developers can focus on the business logic of their applications and delegate the underlying database operations to the ORM library, making the development process more efficient and less error-prone.
