The main difference is in the level of abstraction being considered.

The industry is obviously always moving to higher levels of abstraction and I think its best not to be left behind.

The analysis is done at each level of abstraction identified in the previous step.

The art can be rated on its levels of abstraction or place in time.

"All this is done at such a level of abstraction that it gives no information."

The process has been modeled on a higher abstraction level.

"At your level of abstraction, it doesn't make any difference."

This work will proceed at a higher level of abstraction.

Similar to many concepts in computer science, the term can be used at different levels of abstraction.

At this level of abstraction, 'S' need not be a formal language.
