Used this tool to manage customer's profiles/info in several projects I managed.
You could basically have all the customer's information handy and access to such information is very simple. I truly like the way it's so easy to use and configure and that I can create as many reports as I wish depending on what I need. Customer service is also great! they're fantastic assisting you with any issue you may encounter while using it.
The importing process is a bit too long for my taste if you encounter any errors along the process. However, I am aware Oracle is trying to improve the error messages so it's easier for the user to identify and fix any error.
