Data Modeling: Sample E-Commerce System with MongoDB

The rich document capabilities and atomic operation guarantees in MongoDB makes it possible to model many different applications. Even rigorous requirements of conventional applications like e-commerce system are possible in a document database.

Writing a Comprehensive Unit Test

A common theme amongst people professing “best practices” for unit tests is that you should only write a single assertion for each test. People who make these proclamations rarely show any unit test and those that do only show one. Yet this pattern may require a dozen other unit tests to ensure quality for even a trivial operation. This article uses examples to question that recommendation.

How to Integrate Models And Code

While creating models in a form or another is very common, their combination with the code has been challenging. As a result, models are usually thrown away once the implementation has progressed. The reason is partly in the modeling languages used and partly in the tools applied. The article describes proven practices for working with both models and code.
