If you are developing applications for the IBM i, you can use the Visual LANSA or the LANSA for i development environment. All of your IBM i development needs can be met using the Visual LANSA development environment, and this is the environment recommended for LANSA developers. LANSA for i development cannot use an RDMLX Partition. (For information about Partitions, see RDML and RDMLX Partitions Concepts in the Visual LANSA Administration Guide.
If you are using PC-based tools (such as Visual Basic or Delphi) to develop client/server application using an IBM i database, review 1.1.6 LANSA Open Development.
