In most any business application, you will store and retrieve data from a data store by performing CRUD operations (create, read, update, and delete). In this regard, there are several technologies and tools you can use. For example, you can choose from the available ORM frameworks such as Entity Framework, Dapper, or NHibernate.
However, the challenges go beyond storing and retrieving data. You want to use a tool or an approach that helps you write reusable, maintainable, and flexible code. For that, you can draw on design patterns such as the repository and unit of work patterns.
