Functions can be either bound to a type or unbound. Bound functions Basically there are two different kinds of bound functions: Bound to entity type. Bound to collection of entity type. Bound function can be overloaded but for all bound overload functions with same binding parameter type must have same return type. Unbound functions Unbound functions don’t bound to any type and they are called as static operations. All unbound function overloads MUST have same return type.
