Dashboards vs Reports vs What? First steps on the Analytics path

This is a post about the differences between dashboards and reports, and where they overlap, and how either (or both) can be used to form the foundation of an analytics framework. While most (if not all) of the main points apply across multiple sectors and industries, the focus will be on the use of tools in the rail and also wider transport sectors - that's the intent, anyway!

The first thing is to ask what is the difference between a dashboard and a report - isn't a dashboard a collection of reports or highlights? The answer is, unfortunately, "yes and no": all too often, that is exactly what a dashboard presents, so 'yes'.

When UNIX servers were 'the thing', mainframe and AS/400 systems were legacy; when lower cost PC networks became available, UNIX servers & workstations were pictured as legacy; when Internet systems first became available and "three tier' architectures were in vogue, those same PC networks became the latest 'legacy'. For a while, on-premises systems were legacy and the cloud was where things are - until people started to look at what happens when connectivity fails, other considerations such as latency and contention: at the time of writing, hybrid systems look very attractive, but who knows what next year will bring? …more
