LucidDB

LucidDB

LucidDB is a Database Management System (DBMS) optimized for business intelligence. Besides architectural innovations such as column-store, it supports many advanced features from SQL:2003, including SQL/MED and user-defined transformations written in Java.

LucidDB is the first and only open-source Relational DBMS 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.

Most database systems (both proprietary and open-source) start life with a focus on transaction processing capabilities, then get analytical capabilities bolted on. By contrast, every component of LucidDB was designed with the requirements of flexible, high-performance data integration and sophisticated query processing in mind. Moreover, comprehensiveness within the focused scope of its architecture means simplicity for the user: no DBA required.
