That I can easily see all my data connections from one place as well as having the option to quickly change them if needed. Also allows me to have better control over who needs access to which connection without having to go into each individual file that has been created in some other program. Not sure what others think about it because we use it just like any software would be used. Nothing really bad about it, however you should look around online more before deciding whether or not to purchase. We are able to create files quicker than ever with ease now since they were previously stored separately in multiple places.
