Question

Of the two object-capable data programming methods, what attributes of object relational design make it the more preferred method

Answer 1

Object durability, or persistence is the most preffered attribute in the object relational design. In object oriented progrmming many time you face issue of object storing, you have to explicitly convet to store. Though not auto boxing is present.Persistence is expected to operate with transactional integrity, and as such it is subject to strict conditions.In the real world, you rarely find an object that lacks relations to other objects. Objects are components of object models. The issues of object durability transcends the issue of object model durability and distribution once we make the observation that objects are interconnected by virtue of their relations to one another.The relational approach to data storage tends to aggregate data by type. Rows in a table represent the physical aggregate of objects of the same type on disk. The relationships among objects are then represented by keys that are shared across many tables. Hence, in order to construct an object model, these relationships are constructed from the existing keys at run time in a process referred to as table joins. This is the same well-known property of the relational databases called data independence. Thus it is considered of the important attribute for ORM.
