Nothing much as such but its easy peasy! I can do my report designing in simple manner using this tool which is an amazing discovery of ours within short span of time.The best part about it that i like most hereis no need of any special training/certification required before learning how to use these tools. The whole process would be completed very quickly even if you are just beginner user who knows nothing about IT stuffs too. It is easy to use, it's simple, has a lot of features and is very functional. I do not like that you can't add more than one report at once in the same page. Also, the search function only works when the whole text is typed. The best thing about this tool is its simplicity, it does what it needs to do without getting in the way. We have been able to create reports and dashboards, which are very helpful to our executives who are new to the company.
