Determining the application functional requirements 51
Determining the application functional requirements
Before you can build the sample application, you must understand the functional
requirements underpinning its design. The design of the sample application centers
around the daily tasks performed by Compass Travel’s trip coordinators. These tasks are
listed in the following table:
You can derive several functional requirements for the new application from the
preceding table. For example, the sample application must provide the following
functions:
In the lessons that follow, you will build ColdFusion pages to address each of these
functional requirements. Central to every requirement is the notion of a trip. Before you
can build code to address any of these requirements, you must understand which
attributes of a trip are important to Compass Travel. For this you must determine the
data requirements for the application. Understanding the data requirements is essential to
building the proper database to hold the application data.
Trip coordinator task Description
Produce current trip
listing
To he lp C omp ass Tr av el agents take trip reservations over the
phone and in person, the trip coordinator maintains a list of
current trip offerings.
Provide trip information On an ad hoc basis, Compass Travel management asks the trip
coordinator to develop lists of trips that meet specific criteria.
Maintain trip information The trip coordinator is responsible for keeping all trip information
up to date. To do this, the coordinator needs to locate a trip to edit
it or delete it. Additionally, the coordinator must be able to add a
new trip.
Ensure the quality of trip
information
The trip coordinator is responsible for periodically browsing the
current trip offerings to ensure that all the information is accurate.
Additionally, when adding a new trip or editing an existing one,
the trip coordinator must ensure that the data adheres to the
Compass Travel business rules.
