"The Data Connectedness test checks whether you actually can traverse the network of collaborations to gather all the information you need to deliver the services. (I have seen a major system design fail this test!) "
- from [1] "Object-oriented analysis and design, part 2", by AlistairCockburn, in C/C++ Users Journal, one of the 6 tests for a design. Also on ObjectDesignQuality, but there there are only 5 tests. In the CUJ article there are 6 :
- Data Connectedness
- Abstraction
- Responsibility Alignment
- Data Variations
- Evolution
- Communications Patterns
