Throughout this document effective practices are presented for the management of specimen collections and repositories. I began using this pattern with NHibernate around 2006 and only abandoned its use a few years ago. In the first case, I use a universal repository that can work with any entities. With the Repository pattern, we create an abstraction layer between the data access and the business logic layer of an application. Design patterns and best practices for using Azure Blob Storage Azure Blob Storage is Microsoft's exabyte scale object storage platform built for the most demanding applications and workloads. Ah, I remember now, I wanted to decrease the maximum invalid password attempts from 5 down to 3. The Repository Pattern is an approach to abstract away the details of the data access layer from the rest of the application. It was a Tuesday.

EF Core already implements a Rep/UoW pattern, so layering another Rep/UoW pattern on top of EF Core isn’t helpful.A better solution is to use EF Core directly, which allows you to use all of EF Core’s feature to produce high-performing database accesses. In practice, it is usually a collection of data access services, grouped in a similar way to the domain model classes. The Repository Pattern, according to Martin Fowler, provides a "layer of abstraction over the mapping layer where query construction code is concentrated", to "minimize duplicate query logic". You read a lot of tutorials about the Repository pattern which seem to contradict themselves. Conceptually, a Repository encapsulates the set of objects persisted in a data store and the operations performed over them, providing a more object-oriented view of the persistence layer. It's purpose is to reduce complexity and make the rest of the code persistent ignorant.Adding a Repository pattern on top of this distances you from the features of your ORM. For example, if we are implementing blog application and we want to get the most viewed articles in a few places, we might end up with repeated query logic which would look something like this: We could end up with even more complicated queries, that potentially could be repeated through the code.
