In chapter 4, we dedicated ourselves to the installation, setup, and configuration of all the prerequisites for interacting with a database management system (DBMS), and we learned the means, techniques, and reasons to do that. Now that we have a database context and an object-relational mapper (ORM) up and running, we’re ready to perform the typical data-related tasks: create, read, update, and delete (CRUD) operations, which are handled by Insert, Select, Update, and Delete SQL queries, respectively. Performing these operations with Entity Framework Core (EF Core) allows our MyBGList web API application to interact with the DBMS we set up in chapter 4.
