What is Repository Pattern?

Repository Pattern is a design pattern that allows data access and management to be reduced to a single point in data-centric applications. In this way, regardless of the data source, code duplication and complexity can be avoided by using a single class and a small number of methods for data operations. Repository Pattern also increases testability and flexibility, reduces errors in data operations, and easily adapts to changes.

To use Repository Pattern, first of all, it is necessary to define a general class (BaseRepository) and an interface (IBaseRepository) that will perform data operations. This class and interface include basic operations such as CRUD (Create, Read, Update, Delete), independent of the data source. Then, by inheriting this class and interface, Repository classes and interfaces are created for specific data types. For example, separate Repository classes can be defined for data types such as Category, Product, and Ticket. In addition to basic operations, these classes can also include operations specific to data types.
