| description.long | A micro-ORM for .NET that extends ADO.NET connections to execute SQL queries and stored procedures, supporting both synchronous and asynchronous operations with features for object mapping, dynamic SQL building, and multi-result set processing. | Django provides a database-abstraction API for structuring and manipulating application data through an object-relational mapping layer. It enables creation, retrieval, updating, and deletion of database objects using Python models. |
