The best thing about ovaledge is that it does not require any additional software or hardware setup for its use. I can simply upload my csv file and start working with it in no time! Nothing really as such, but i would say if you are looking forward to using this tool then make sure that you have ample knowledge of sql queries and other programming languages like python etc. This will help you get better results from oval edge. We used oval edge for our business analytics purpose where we were required to extract information from various sources which was stored in different formats (csv).
