ORM Libraries
ORM (Object-Relational Mapping) libraries are software tools that map object-oriented programming language constructs to relational database tables, enabling developers to interact with databases using objects and methods instead of raw SQL queries. They abstract database operations, handle data conversion, and manage relationships between entities, simplifying data persistence and retrieval in applications. Common features include query building, transaction management, and schema generation.
Developers should learn ORM libraries when building data-driven applications, such as web services, enterprise software, or content management systems, to reduce boilerplate SQL code, improve maintainability, and enhance security by mitigating SQL injection risks. They are particularly useful in projects using object-oriented languages like Python, Java, or C#, where they streamline database interactions and support rapid development with features like migrations and caching.
