Adding Operations of describe function 

Whenever take a look at the operations in OOPs you find queries about attributes or associations in object model (such as student.name), to events in dynamic model (for example ok, cancel) and to functions in functional model (such as save, update). 

You can see operations from object model. It contains reading and writing attribute values and association links. In object model operations are presented through an attribute. While analysis nothing is private, you suppose that all attributes are accessible.  

Accessing from one object to other through object model can be termed as "pseudo-attribute" like Account.Bank, where as account and bank is two separate objects of their individual classes.
