Abstract
With the emergence of Big Data era, real-time analytics data management systems are highly in need in the areas such as business intelligence, predictive analytics. Column-oriented database is created as a type of NoSQL databases to fulfill these needs. {sc ScalaTion} has a column-oriented in-memory database which can handle real-time analysis. The database provides an easy way to transform the table into matrix to later fill into the advanced machine-learning models which are also available in {sc ScalaTion}. Different dimensions of performance evaluations show analytic performance of {sc ScalaTion} is better than open-source RDBMS. The system also provides RelationFrame API which offer higher order functions for users to manipulate data in a compact way.
