Is it possible for access data from two different database such as...

SELECT A.EMP_NAME, B.DEPT_DESC FROM DB1.TB1 A, DB2.TB1 B WHERE
A.EMP_DEPT = B.DEP_KEY

If so how?

Answer:

Yes, this is called a heterogeneous join. An example of this is like:
1   
2   SELECT DISTINCT c.cust_no, c.state, o.order_no, i.price
3   FROM ':Local_alias:customer.db' c,
4        ':IB_alias:order' o,
5        ':SYB_alias:lineitem' i
6   WHERE o.cust_no = c.cust_no and
7         o.order_no = i.order_no


The first part between the :: is the BDE alias for the database you want to include 
in the heterogeneous
join.
