Cubes - Online Analytical Processing Framework for Python

Cubes is a light-weight Python framework and set of tools for Online Analytical Processing (OLAP), multidimensional analysis and browsing of aggregated data.

Focus on data analysis, in human way

Overview

Purpose is to provide a framework for giving analyst or any application end-user understandable and natural way of presenting the multidimensional data. One of the main features is the logical model, which serves as abstraction over physical data to provide end-user layer.

Features:

OLAP and aggregated browsing (default backend is for relational databse - ROLAP)multidimensional analysislogical view of analysed data - how analysts look at data, how they think of data, not not how the data are physically implemented in the data storeshierarchical dimensions (attributes that have hierarchical dependencies, such as category-subcategory or country-region)localizable metadata and dataSQL query generator for multidimensional aggregation queriesOLAP server – HTTP server based on Flask Blueprint, can be easily integrated into your application.

Download

Current recommended version is 1.1.x. It hasn't been yet tagged so please use the master branch. This version includes SQL backend support out of the box, and other backends have been moved to separate projects (ie. MongoDB). This branch (currently master) will be soon tagged as 1.1 release.

Previous stable version was 1.0.1. This version included all backend types, but no further development will be done on this branch.
