While there are trends towards including more discovery capability and towards supporting NoSQL data sources the vendors are significantly fragmented at present. Only a relative handful of suppliers have extensive support for the latter—particularly if you are interested in anything beyond Hadoop—while there remain a number of vendors that do not offer much in the way of discovery and the ability to understand relationships in and across data sources. Indeed, even across the leading companies in this market, the top 5 vendors for profiling only average 9% higher scores than the next 5; conversely, the leading 5 providers of discovery capabilities average 27% better ratings than the next 5 suppliers. In effect, profiling is on the way to becoming commoditised but that is very far from true when it comes to discovery.
