Thus far, the discussions of object-oriented analysis and design have focused on modeling the functional design and the internal processing of the application. Successful modern software applications rely on a rich set of graphical user interfaces (GUIs) to expose this functionality to the users of the application. In modern software systems, one of the most important aspects of an application is how well it interacts with the users. Gone are the days when users would interact with the application by typing cryptic commands at the DOS prompt. Modern operating systems employ GUIs, which are, for the most part, intuitive to use. Users have also grown used to the polished interfaces of the commercial office-productivity applications. Users have come to expect the same ease of use and intuitiveness built into applications developed in-house. The design of the user interface should not be done haphazardly; rather, it should be planned in conjunction with the business logic design. The success of most applications is judged by the response of the users toward the application. If users are not comfortable when interacting with the application and the application does not improve the productivity of the user, it is doomed to failure. To the user, the application is the interface. It does not matter how pristine and clever the business logic code may be; if the user interface is poorly designed and implemented, the application will not be acceptable to the users. It is often hard for developers to remember that it is the user who drives the software development. Although UML was not specifically designed for GUI design, many software architects and programmers have employed some of the UML diagrams to help when modeling the user interface of the application.

established before starting to code when building the requirements document for the project, as explained in Appendix B. However, for the purposes of this book, we prefer to deal with things one at a time. After the structure of the catalog is established, you ll start writing the code that makes the catalog work as planned.

setservent()

The setservent() function opens the services file and rewinds the file pointer to the beginning. This allows you to call getservent() repeatedly to iterate over the service entries. The setservent() function has the following signature:

Today s web surfers are more demanding than they used to be. They expect to find information quickly on whatever product or service they have in mind, and if they don t find it, they are likely to go to the competition before giving the site a second chance. Of course, you don t want this to happen to your visitors, so you need to structure the catalog to make it as intuitive and helpful as possible. Because the e-store will start with around 100 products and will probably have many more in the future, it s not enough to just group them in categories. The store also has a number of departments and each department will contain a number of categories. Each category can then have any number of products attached to it.

void setservent(int stayopen);

Note Later in the book, you ll also create the administrative part of the web site, often referred to as the

getservent()

Control Panel, which allows the client to update department, category, and product data. Until then, you ll manually fill in the database with data (or you can cheat by using the SQL scripts provided as part of the Source Code/Download section of the Apress web site at http://www.apress.com, as you ll see).
