The main purpose of Object-Relational Mapping (ORM) is to facilitate the interaction between object-oriented programming languages and relational databases. It enables developers to manipulate databases using objects, which aligns with the programming paradigm of object-oriented languages.
For example, in a typical object-oriented application, data is represented as objects with attributes and methods. However, relational databases store data in tables with rows and columns. ORM acts as a bridge between these two paradigms by mapping objects to database tables and their attributes to columns.
This allows developers to perform database operations such as creating, reading, updating, and deleting records using object-oriented code, without writing raw SQL queries. ORM frameworks handle the conversion between the object model and the relational database model, making the code more maintainable and portable.
In the context of cloud computing, ORM can be integrated with cloud-based databases to simplify data access and management. For instance, Tencent Cloud offers various database services like TencentDB for MySQL, which can be used in conjunction with ORM frameworks to build scalable and efficient cloud applications.
