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 analysis
- logical 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 stores
- hierarchical dimensions (attributes that have hierarchical dependencies,
such as category-subcategory or country-region)
- localizable metadata and data
- SQL query generator for multidimensional aggregation queries
- OLAP 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.

Report bugs using github issue
tracking.
Development
If you are browsing the code and you find something that:
- is over-complicated or not obvious
- is redundant
- can be done in better Python-way
