A Constant Database (or CDB) is a database intended to be read many times but only written to once. Dan Bernstein created a constant database specification and programs to utilize it on Unix systems, refer to his his CDB page.

CDBs are very commonly used in mail systems such as Qmail.

Michael Tokarev has created an implementation called TinyCDB that can be used with the Postfix MTA.
