3. Summary Blue Sky Bookstore is an independent bookstore. Oriented to both the general reader and to studious individuals who may research or read widely. The software proposed here will automate several ordinary functions of Blue Sky’s bookselling. More importantly, will add a basic shelf-inventory system. Ordinary functions are: 1) Selling books 2)Controlling the cash drawer by Staff Members, 2) Keeping quarterly sales tax data, and 3) Tracking staff logins. Inventory functions will basically keep an accurate database of what books are supposed to be on the shelves. Future enhancements may include: 1) tracking customer special orders of books, 2) keeping raw time clocking data for employee payroll, and 3) tracking the owners’ current orders from suppliers and publishers.
