El,

As of what I know.....

cluster r very big but small number of logical tables grouped together and assigned a table cluster. These clusters stores control data and also used for to store the temporary data or text.

where as view combines the tables based on the application you know like..

View is a logical grouping of fields from different tables and it holds data of different tables together. If you don't want any fields from any table u can skip and if u want you can hide also. view can be used in ABAP programs for data selection.

The data of a view is derived from one or more tables, but not stored physically.

If anything wrong in it sorry for that...
