WinTree converts the selection rules created by a user into ANSI
C code. This allows the selection rules to be run on a variety of
platforms. The WinTree system automatically controls the compilation
and execution of the selection rules on a user specified platform.
Multiple platforms can be supported at the same time. For example,
development and testing can be done locally on a users workstation
using a sample cross section of the data. After development and
testing, the selection rules can be sent to another platform, a
large Unix system, for example, for production execution. The user
does this by simply selecting the desired host on which to run the
selection rules. This approach allows for rapid development and
testing of complex selection rules.
WinTree was designed to be open ended. That is, it was designed
to be extendible by the user. This is accomplished by allowing the
user to write functions and subroutines that can be incorporated
into the selection rules and by allowing the runtime selection driver
to be partly or wholly modified by the user. WinTree provides a
selection architecture with substantial functionality that can be
extended by the user. WinTree was also designed to be able to fit
into an existing promotion system. In this sense WinTree has no
predefined input or output record formats.

Figure 1 shows a small promotion tree. The tree represents a
promotion by a bank that wants to promote some financial products.
The products are Investment services, CDs and Checking. The universe
of people, represented by the root node, here labeled BankPromo,
was divided into four sub sets: BadCredit, DoNotAsk, Promote and
NoPromote. As can be seen in this example, 48 people are considered
to have bad credit and as such are not eligible to be promoted.
Also, 49 people specifically requested not to be promoted. This
leaves 903 people eligible to be promoted. The right most node on
the second tier is the set of people who, for some reason that is
defined by the rules in the nodes under the Promote node, were not
promoted.
