Shared Columns

Hi "anybody",

(1) I was just wondering whether is there any way whereby
ONE physical column in a particular table can have two different column names (redefine). In this case, performance is very important.

(2) Can someone tell me more about the audit features in Oracle?

(3) Does the system catalog tables keep track of the date

	    and time whereby the schema of a particular table is modified?
	    If it does, what about at database level? Is there any time
	    stamp to indicate the last modified date and time when
	    the database schema is modified?



	(4) What's the difference between OCI calls and Pro/C product?


	    In terms of performance, which is better? 

Thank you very much to whoever take the trouble to read till here..;-)
