SQuAVisiT: A Software Quality Assessment and Visualisation Toolset

Software quality assessment of large COBOL industrial legacy systems, both for maintenance or migration purposes, mounts a serious challenge. We present the Software Quality Assessment and Visualisation Toolset (SQuAVisiT), which assists users in performing the above task. First, it allows a fully automatic extraction of metrics, call information, and code duplication from COBOL source code. This information, stored into a database, can be easily converted and exported to a set of visualization tools. We incorporated several such third-party tools for the visualization of call relations and system structure, and metrics visualization. These tools use novel visualization techniques such as bundled edges, matrix plots, and table lens. We illustrate the usage of our tool with an industrial case study on
