This month we'll look at pattern discovery in more detail by continuing to
examine a business application pattern we discovered and documented. Our
focus isn't on creating formal patterns, but on capturing, refining, and
sharing the knowledge gained during development. We'll discuss the steps we
went through as we discovered and captured our pattern. As we progress
through the steps, we'll show you not only what we learned as we captured
this pattern, but also things we learned as we captured other patterns.
In Part 1 we identified the problem - managing configurable balance
information in the area of warehouse management, and the candidate pattern -
encapsulating the criteria for the balance information in the
ProductBalanceMapKey class, as shown in Figure 1.
Now we'll... (more)
Over the past two months, we've looked at the process of extracting a
business application pattern from a series of business requirements. You've
seen this pattern take shape, from its original form as a design meeting the
specific needs of a particular business application (configurable product
balance information) through an initial abstraction that was modified by
other business requi... (more)
You're probably saying to yourself, "Oh, no! Not another patterns article!"
Technically, that's what this is. However, instead of simply showing you a
finished pattern, we're going to look at pattern discovery. And, while what
we'll talk about can help you capture fundamental patterns (that is, if there
are any fundamental patterns left to be defined) we're going to focus on the
capture ... (more)
