>>.Say if the size of datbase is 1.75TeraByte then how many tables exists in the database for this datasize [i need an approximate figure, if possible] and number of rows that is possible in a table.

you have a database of size 1.75 TB.
You want to find how many tables exist.
There is no generalized theory to predict this.
login as admin user and issue

sql>select count(*) from dba_tables;

>> number of rows that is possible in a table.
Virtually unlimited.

Batch loading is a process where you load data in a series of steps and usually it may handly huge volumes of data.
Typically used in warehouse or any such environment
