Hi All: What are the OO database

[parimalpat]

Hi All:

What are the OO databases available in the market that supports Query-By-Example?

for eg:

Person person = new Person();
person.setFirstName("John"
person.setLastName("Smith"
person.friends = new Map(); //Or any Key-value datatype
person.friends.put("Friend1", "Bill"
person.friends.put("Friend2", "Jim"
person.saveToDatabase();

Person findThisPerson = new Person();
findThisPerson.setFirstName("John"
findThisPerson.friends.put("Friend1", "Bill"
person.findFromDatabase();

Thanks,
Parimal
