In Entity Framework, how do I add a generic entity to its corresponding DbSet without a switch statement that enumerates all the possible DbSets?
c#,database,entity-framework,entity

What is the best way to build a model/entity in Scala to map with Squeryl?

How to properly update a managed entity using data from a non-managed entity?
Controlling what Doctrine persists Update existing entities only if required.

Symfony2 - Entity Collection Choice Restriction

This will restrict the...
Is it good practice to have a getter for every property in a class representing a row, or should I investigate another approach?

Single or Multiple Entity managers
java,rest,jpa,entity,eclipselink
I assume that you are developing a Java SE solution or a Java EE web profile application, i.e. your persistence.xml lookd something like this <persistence-unit name="puName" transaction-type="RESOURCE_LOCAL"> In this case you get your EntityManager like this EntityManagerFactory emf = Persistence.createEntityManagerFactory; EntityManager em = emf.createEntityManager; You can safely store the EntityManagerFactory...
