Analytical Databases edit 
Our list of and information on commercial, open source and cloud based analytical databases, including Teradata, Exadata, Redhift and alternatives to these. Full stack databases (supporting both storage and query of data) that focus on analytical or OLAP use cases that generally involve large scanning or aggregation operations. Typically support distributed parallel execution of queries (and are therefore commonly referred to as MPP databases) with columnar compression, and often support a range of analytics beyond SQL queries, for example cube based MDX queries, machine learning, graph or geographical analytics. Some technologies also support a level of query federation using external tables (for example over data in Hadoop). Some technologies run over Hadoop (exploiting HDFS and YARN), but will either use their own proprietary data format or will be positioned as a self contained analytical database. The following analyst material covers a number of technologies in this category:: See our Query Engines page for details of technologies that support similar capabilities but over external data (e.g. data in HDFS or source databases).Category Definition
