MongoDB Schema Design Basics

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.

Paper: Google Fusion Tables: Data Management, Integration and Collaboration in the Cloud

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.

Rethink Your Data Model

Karl Seguin[1]:

Fundamentally rethinking how you model data is actually a really fun thing to do. Modeling data for a relational database is such second nature, that you constantly have to stop your brain from doing what comes naturally. Why would you want to do that, you might ask? Because we’ve been modeling more or less the same way for decades, it’s time we challenged ourselves, experimented and learned.

Polyglot programming has brought us back the beauty of learning, experimenting, and using any programming langauge. Polyglot persistence is the equivalent in the data space: gaining back the option to learn, experiment, and use the best data models, storage engines, and distribution models.
