ClickHouse® is a fast, open-source column-oriented database management system that can generate analytical data reports through SQL queries in real time. According to several independent benchmarks, it far exceeds other comparable column-oriented database management systems, working even up to 1000 times faster. It is able to process hundreds of millions to more than a billion rows and tens of gigabytes of data per single server per second. Apart from its blazing speed, ClickHouse is highly...

Mondrian is an OLAP (online analytical processing) engine written in Java. It reads from JDBC data sources, aggregates data in a memory cache, and implements the MDX language and the olap4j and XML/A APIs.

Postgres-XL is a PostgreSQL-based scale-out cluster that handles both OLTP write intensive workloads as well as OLAP/BI type of workloads thanks to MPP parallelism. Postgres-XL is fully ACID and supports cluster-wide Multi-version Concurrency Control (MVCC) for global consistency and performance. There are commercial companies such as 2ndQuadrant, who provide support and consulting around Postgres-XL. Please visit http://2ndquadrant.com/en/resources/postgres-xl/ for more details.

olap4j is an open Java API for connecting to OLAP servers and writing analytic applications. Code is at https://github.com/olap4j/olap4j.

LucidDB is a 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.

Palo ETL Server is a Java based Tool for Extraction, Transformation and Loading of mass data into the Palo OLAP Server. Palo ETL Server is one part of the Palo Suite.

jdbc4olap is a ready-to-use JDBC 3.0 driver that provides access to OLAP databases. Relying on a relational representation of multidimensional environments, it includes a SQL-MDX converter and uses XMLA to dialog with OLAP servers.

Google Web Toolkit-based tool for publishing user-friendly OLAP views, reports and dashboards. Uses Mondrian OLAP and a relational database as the back-end.

jIntersect is an OLAP like Java algorithm that takes a JDBC ResultSet as input and returns a data structure with all possible intersections, combinations and permutations of the data, pre-summarized at multiple levels for quick access.

BIOLAP - OLAP for Genome and Biology Data Sets. This project extends Mondrian OLAP to biology data sets. We provide tools to slice and dice genomic sequence similarities and more easily explore large genomic data sets.

OpenRolap: an implementation of OLAP in a relational database. Conceptually simple, the current version is in MySQL, with a Java API. The API aims to avoid complex MDX-type language, instead to use a simple "filter path" structure.

Define a simple and pragmatic model for a client-server OLAP engine suitable for use in a database agnostic web based architecture, and implement this in a variety of languages for a variety of platforms. Rework of original XML-OLAP project.

something for OLAP :-)

Server which supports Palo MOLAP (www.jedox.com) HTTP API but uses as data storage traditional relational database.

Firewater is an open source scaleout RDBMS based on column store technology. It allows a cluster of commodity servers or virtualized cloud nodes to be used for fast response times on SQL and OLAP queries over massive datasets.
