Visual Data Mining in Software Archives to Detect How Developers Work Together

A transaction overview

A transaction overview

Lots of transactions are produced in evolving software systems, i.e. many files are checked in to a repository together by the same developer at a specific point in time. In this work we developed several interactive visualizations to understand the transactions of files together with the developers who checked in the files, i.e. who were responsible for such a transaction.

The transaction overview looks very similar to a bar code and can be used as an overview representation even for larger and longer datasets. The file author matrix shows a more direct correlation of developers and files and the dynamic author file graph uses animated node-link diagrams to show such evolving correlations.

If you are interested in our work please read our paper presented at the Mining Software Repositories Workshop in 2007.
