Access Layer Various database development libraries interrogate metadata, such as primary key, domain and similar structural information, in order to make development of client applications easier. It would not take long to discover the key simply by comparing the decompiled versions of your custom Firebird build with the normal, unencrypted version. Various database products do exist which purport

v.2.0, it is no longer necessary and the server itself does not need this option. However, some custom UDFs may use the Win32 messaging facilities and this option allows them to work as expected. Known 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
