If you're a tennis fanatic, this program was tailor-made for you. The application is essentially a guide to everything that anyone has ever wanted to know about tennis (at least for the last quarter century), with lists of tournaments, players and events since 1980. It has an intuitive, Windows XP-like interface; users can simply click on various icons to view corresponding lists of tournaments and players. All of these can be sorted by various parameters, such as country or type. Navigation is easy and smooth, even including a "Back" function that lets users back up a screen. All data can be exported with a mouse click to Excel, and the information can be automatically updated to stay current. It's a large database--the download size is almost 20MB. But for people who live and breath tennis, even this plethora of information won't be too much.
