Before we begin…Do your homework!

• Research the RPG program! Many details can be overlooked! What is it doing well, not so well

• Talk to primary user! Are there additional needs! Are there additional needs! Would a web version truly help them! Will they still require hard-copy

• Prepare for the onslaught! Once one user gets web based solutions, they all want them!


Step 1: Connect to DB2

• Use DB2_Connect function! Why not i5_connect? Could have done

• A few words about authority! If your data sets are *PUBLIC *Read, no auth necessary! Can do authentication a couple of ways! Can do authentication a couple of ways! Or hard code userid and password
