Object modelling?

please,could any body help me about what is the different between object modeling and object oriented modeling .
and why we use object modling in requirement just ,and the other in design and implementation.
thankes

Hi Hanan,

I moved your question to general help.

We use Class or "object" in UML to model virtually anything. So, we can use it in Requirements too as a sort of container for requirements specification.

In implementation, we use Classes / objects for design which directly corresponds to the related concepts in object-oriented languages such as Java, C++ or C#.

Hope, this helps.
