The ease of use, the ability to have a very high level of customization of the UI. There is no other tool that is more versatile or has a richer set of features than Savitas. The documentation and online training material are also great. It's a great tool for data integration. Savitas is a very complex tool with lots of features. There is a learning curve, but once you get it, you will find that you can use it to integrate almost any type of data. Savitas is used by us to integrate data from multiple customer databases into our own. This has allowed us to have a single view of our customers and their data.
