How many interfaces required?

Question

Hi
I am relatively new to ODI. I have 2 different sources for Vendor, need to go in the single Target table. Say Source A and B. After first full load the source files are going to be increamental
1. I have created staging interface INT_STG_A to load source file A into staging table A
2. created staging interface INT_STG_B to load source file B into staging table B
Questions:
1.
Should I create staging interface INT_STG_AB to load table A and B into staging table C and then create a Target Interface to load Table C into Target Table D?
or
Should I create target interface INT_TARGET_A to load staging table A into Target table D and create target interface INT_TARGET_B to load staging table B into Target table D
2. Any other approach? and Pros and Cons
3. What are two pass and 3 pass approach?
4. Do I require atleast 4 interfaces to achieve the above?
Thanks

Hi ,
You can do that using two interfaces.
In first interface - > join table A and B target will be table staging C
if its just insert ( appending the table ) use Control Append KM . ( other wise you can use Incremental update KM )
Now in second step ( interface )
just move the things form table C to target table ( final table )
in Brief using 2 interfaces u can achive this.
