Databases in Erlang

Dictionary

Data can be stored in many ways in Erlang. Each process has a local dictionary that uses put and get.

undefined
3> get(hello).
world

Data can be stored with the ETS (Erlang table storage system) via the ETS library. It creates data at the process level. See Using_Ets.
