data model: All content tagged as data model in NoSQL databases and polyglot persistence
For NoSQL databases there are no clear rules like the Boyce-Codd Normal Form database normalization. Data modeling and analysis of data access patterns are two fundamental activities. While over the last 2 years we’ve gather some recipes, it’s always a good idea to check what are the recommended ways to model your data with your choice of NoSQL database.

This paper from Google talks extensively about the usage of BigTable and Megastore, the data model, query processing, and transaction handling in the implementation of Google Fusion Tables.
Google Fusion Tables is a cloud-based service for data management and integration. Fusion Tables enables users to upload tabular data files (spreadsheets, CSV, KML), currently of up to 100MB. The system provides several ways of visualizing the data (e.g., charts, maps, and timelines) and the ability to filter and aggregate the data. It supports the integration of data from multiple sources by performing joins across tables that may belong to different users. […] This paper describes the inner workings of Fusion Tables, including the storage of data in the system and the tight integration with the Google Maps infrastructure.
