Another FAQ

Doesn't DB_File already do something like that?

• DB_File is a great piece of software

• Unfortunately, the DB_RECNO feature is not as great as the rest of it

• DB_File reads the entire file into memory immediately

• It makes all the changes in memory

  • This is impractical for large files

• It writes out the entire file when you untie it

  • This is wasteful when you're only making a few changes near the end

  • Or making fixed-length changes

• All this prevents useful concurrent access
