any framework for creating hierachy of object with expandable attributes and CRUD operation

[Andrew Ng]

Hi Everyone,
I have a problem scenario here with the following description

A generic object with a fix set of attributes that is flexible enought to
allow addition of more attributes programmatically.
The object can be atomic in nature or a container that contain object of
similar kind. A hierachy can be constructed out
of a group of these object. Create, Read, Update and Deletion operation must
be supported. Search operation must also be supported.

I am looking for a framework or pattern that can handle this. Is there a
name to the above mentioned problem scenario ?

In Java a HashTable should be able to do that.

You can do
Object a; Object b;
...
Map myMap = new HashTable();
myMap.put("a", a)
myMap.put("b",b)
