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.
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
- OLAP server (WSGI HTTP server with JSON API based on Wergzeug)
