Easy to use, I liked the ability to see the data in several ways from various data sources. I didn't like that it would not allow you to add more than one data source. I also didn't like that it would not let you change the date to a different format. I had no problems with instantOLAP. It was easy to learn, and it was easy to put on the server. I would have liked to have been able to change the date formatting. I also would have liked to have been able to add more than one data source. I would recommend instantOLAP to anyone who wants a easy reporting tool. I am easily able to get the information I need from instantOLAP. I wish I could have added more than one data source and changed the date formatting.
