LucidDB is an open source database purpose-built to power data warehouses, OLAP servers and business intelligence systems.
LucidDB is the first and only open-source RDBMS purpose-built entirely for data warehousing and business intelligence. It is based on architectural cornerstones such as column-store, bitmap indexing, hash join/aggregation, and page-level multiversioning.
Due to its purpose built architecture and features designed for BI and Data Warehouse workloads it typically performs faster than traditional row store databases, without any additional tuning.
LucidDB is the result of an ongoing effort by a number of different organizations and individuals. It was started as a collaboration between LucidEra, Inc. (a software startup) and The Eigenbase Project (a non-profit organization). Much of the technology was adapted from an earlier venture (Broadbase Software, which produced the industry’s first turn-key data mart product). LucidEra acquired the rights to this codebase, integrated it into the pluggable DBMS framework provided by Eigenbase, and contributed the result (LucidDB) back to Eigenbase as open-source software under the terms of the GPL. LucidEra went out of business in June 2009, but Eigenbase sponsorship for the community effort continues, providing project hosting resources such as source control and release management; Eigenbase also oversees coordination with related projects.
