At install time, your choice is most likely to be whether to use Classic or Superserver. For development, there's nothing in it. For testing and deployment, the choice may be more important. Superserver's only one system user exclusively, which makes it impossible to use in many integrated application development environments. 14 Chapter 3 Installing on Windows Please read the previous chapters before you model as one you can design for, using one of the full server models for initial acquaintance and development.
