Join the chat at

Flattr this git repo

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


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.


  • 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.


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.

See examples directory in the source code repository for simple examples and use-cases.

See for more complex examples.


For cubes models see


Source code is in a Git repository on GitHub

git clone git://

After you've cloned, you might want to install all of the development dependencies.

pip install -e .[dev]

Build the documentation like so. ::

cd doc
make help
make html

Outputs will go in doc/_*.


Python >= 2.7 and Python >= 3.4.1

Most of the requirements are soft (optional) and need to be satisfied only if certain parts of cubes are being used.


If you have questions, problems or suggestions, you can send a message to the Google group cubes-discuss.

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

... please let it be known.
