What is strategy pattern used for?

In computer programming, the strategy pattern (also known as the policy pattern) is a behavioral software design pattern that enables selecting an algorithm at runtime. Instead of implementing a single algorithm directly, code receives run-time instructions as to which in a family of algorithms to use.

What is the purpose of strategy pattern?

How does the strategy design pattern work?

Strategy Design Pattern is a type of behavioral design pattern that encapsulates a “family” of algorithms and selects one from the pool for use during runtime. The algorithms are interchangeable, meaning that they are substitutable for each other. The key idea is to create objects which represent various strategies.

How to implement persistence ignorance in Poco domain?

If you use POCO domain entities, your domain model classes are persistence-ignorant, following the Persistence Ignorance and the Infrastructure Ignorance principles. Per DDD patterns, you should encapsulate domain behavior and rules within the entity class itself, so it can control invariants, validations, and rules when accessing any collection.

What kind of persistence is used in relational databases?

When you use relational databases such as SQL Server, Oracle, or PostgreSQL, a recommended approach is to implement the persistence layer based on Entity Framework (EF). EF supports LINQ and provides strongly typed objects for your model, as well as simplified persistence into your database.

How to implement persistence in EF Core 1.1?

Since EF Core 1.1, to satisfy those DDD requirements, you can have plain fields in your entities instead of public properties. If you do not want an entity field to be externally accessible, you can just create the attribute or field instead of a property. You can also use private property setters.
