The best thing about verta is that I can easily make my own data models in formulae or tables which gives me flexibility for further use as per requirement without any coding effort at all! Nothing much but we need more features like creating our custom functions etc so this would be nice if they add these things too! And yes i have been using their services since last 3 years now till date no issues faced by us only happy customers are there who enjoyed working through out process while generating reports from data base.
