Deep Diving into EF Core: Q&A with Jeremy Likness

Entity Framework (EF) Core is a cross-platform, extensible, open-source object-database mapper for .NET. Since its first release in 2016, EF Core evolved until reaching its current form: a powerful and lightweight .NET ORM. InfoQ interviewed Jeremy Likness, program manager for .NET Data at Microsoft, to understand more about EF Core and what we should expect for its next release later this year.

Interview with Entity Modelling Tool Creator, Frans Bouma

Our first .NET interview of the year is with Frans Bouma of the entity modeling tool LLBLGen Pro. This tool has been around for almost as long as .NET itself, but being a commercial product it isn’t as well-known as the free alternatives.

Advanced Use Cases for the Repository Pattern in .NET

In our previous article, we looked at the basic patterns needed to implement a repository. In many cases these patterns were such a thin layer around the underlying data access technology they were essentially unnecessary. However, once you have a repository in place, many new opportunities become available.

Implementation Strategies for the Repository Pattern with Entity Framework, Dapper, and Chain

This article will focus on the basic functionality that one would find in a typical repository created with .NET. We’ll look at both general functionality and how that functionality would be implemented using three different styles of ORM: Entity Framework, Dapper, and Tortuga Chain.

Starcounter vs. ORM and DDD

The so-called “object-relation impedance mismatch” has long been discussed in engineering circles. Most attempts at a solution rely try to mask the issue by pulling logic into the application tier. Kostiantyn Cherniavskyi looks at these issues and shows how many of them can be solved with hybrid databases such as Starcounter.

ActiveJPA – Active Record Pattern for JPA

ActiveJPA is a Java implementation of Martin Fowler’s Active Record pattern that wraps around JPA and provides useful abstractions to simplify data access. With ActiveJPA, models themselves act as a DAO and interact with the database without requiring additional code for the DAL. In this article the primary committer discusses ActiveJPA and provides plenty of usage examples.

Don’t jump the SQL ship just yet

The SQL language has been evolving steadily over the last two decades. At the same time, the verbosity caused by the JDBC API in Java client code and the lack of first class SQL support within the Java language have led to the introduction of ORMs such as Hibernate, which was later standardised into JPA and the Criteria API.If SQL and JPA are diverging, where will our data interaction patterns go?
