IF WE SELECT THE TARGET LOAD TYPE IS NORMAL, THEN DATA
MOVEMENT IS ROW BY ROW AND STORE AN INSTRUCTIONS IN SESSION
LOG FILE.IF SESSION FAILS, WE CAN RECOVERY THE DATA USING
SESSION RECOVERY AND DATA LOADING IS SLOW. BUT IN BULK TYPE
LOADING DATA IS FAST AND IT DOESN’T MAINTAIN THE SESSION
LOG FILE. IF SESSION FAILS WE CANNOT USE SESSION RECOVERY
IN BULK MODE.
IF I WRONG MEANS PLEASE SEND THE MAIL TO ME

The major difference is while going with normal load,we can
have session recovery whereas in Bulk loading we can't.
Some of the other differences are as follows:
Normal Bulk
1.Enters session log before 1.Doesn't enter the session
loading into target there by log and loads directly in
increasing the loading time. target there by decreasing
the loading time.
2.Less performance. 2.High performance.
3.Indexing possible. 3.No concept of indexing.
4For small amount of data. 4.For huge amount of data.
Please let me know if you have any further differences.
Thanks.

Answer / chandrababu.sarupuru
Normal loading will load data row by row and it will create
the datalog for each and every record.
Bulk load will load data in bulk size at a time.It is very
faster than Normal loading .
But in case of session recovery we need data log to recover
the session.

Answer / ananta mishra
1-normal loading will load data first in log file then load
in target.
but bulk loading load the data directly in target.
2- performance will increase where bulk loading will use.
3-u can't recover data when use bulk loading.so for that we
have to start workflow again.
