Evaluation and Testing of Database Backends in an Erlang System

Abstract: In this paper I will discuss and evaluate two database managers, Tokyo Cabinet and CouchDB, and give an example of how they can be integrated in an Erlang system that currently is using Mnesia, the major Erlang database management system. I will also highlight the interesting features of Tokyo Cabinet and CouchDB with aspect of a financial system that is highly dependent on transactions with requirements on high consistency and availability. I am using the TPC-B benchmark suite for the performance evaluation.
