These functions allow you to store records stored in a dbm-style
|
|
|
|
|
database. This type of database (supported by the Berkeley DB,
|
|
|
|
|
GDBM, and some system libraries, as well as a built-in flatfile
|
|
|
|
|
library) stores key/value pairs (as opposed to the full-blown
|
|
|
|
|
records supported by relational databases).
