5 Chapter 5. Building the base scenario: Stage 2 In this chapter we extend the base J2EE scenario we created in Chapter 4, "Building the base scenario: Stage 1" on page 53. We are now adding a DB2 environment. The reason for this is to take into consideration the potential data growth and subsequent server performance implications when storing a huge amount of large XDFL files on the file system. Storing the forms in DB2 gives you scalability, reliability, and database search capabilities.
