Open Source Erlang Database Software

Scalaris is a scalable, transactional, distributed key-value store. It was the first NoSQL database, that supported the ACID properties for multi-key transactions. It can be used for building scalable Web 2.0 services. Scalaris uses a structured overlay with a non-blocking Paxos commit protocol for transaction processing with strong consistency over replicas. Scalaris is implemented in Erlang.

ErlMySQL is a MySQL client written in Erlang and provides API that is very close to Connector/C library. The client is using low level (TCP/IP socket) connection to MySQL server and allows to exchange a data with maximum possible speed. Multiple datasource support and connection pool are incapsulated in the client that increases a performance in concurrent environment.

AMNESIA is an Erlang library providing an abstraction layer for interfacing relational DBMSs. It allows designers to integrate relational databases in Erlang programs using native Erlang types and language constructs.

The Bluetail Ticket Tracker (BTT) is a system for creating, storing and keeping track of tickets. BTT can also store customer info and mail, as well as general information structures (e.g FAQ).

Resource pool project is written in Erlang as a tiny library. The goal of the tool is reduce the overhead of creating new resources by reusing of the same resources among multiple processes. Achieving result is better performance and throughput. The resource pool was inspired by Java Apache's commons pool and adopts API and main principals from this project. Database connection is most popular example for pooling resource.

A semantic memory software tool “reflects” one's “imagination”. In it, arbitrary concepts may be described, stored, arranged, transformed, and shared. One may verbalize thoughts as they arise in the mind to externalize and digitize “mental obj
