The Patterns of Enterprise Application Architecture<https://www.amazon.com/Patterns-Enterprise-Application-Architecture-Martin/dp/0321127420> refer to this has an Identity Map. It means that if you go
Var a = Airplane.Load(1) Var b = Airplane.Load(1) Then a will equal b sine the Idenity map will recognise that you have already loaded Airplane number 1 and loading it again will simply pull it from memory. If they are loaded from the DB twice and are in different parts of memory then a will not equal b. From high level programming perspective this is a bad place to find yourself in. (I don’t know if the EF has an identity map.) To pull of an identity map you will need to bind it to a transaction scope and a basic caching algorithm.
