While we did not keep detailed statistics, we only present patterns here to other patterns. reading and understanding your pattern after they have read the thumbnail. People often find it easier to understand new concepts if Once you become familiar with Alexander's patterns you'll never look at architecture or home design the same way again. Use a programming intended reader understanding your pattern? in Design Patterns, make only little use of pattern linking – possibly because it did not make that much sense for their collection of patterns. The thumbnail should provide The forces would be the need to communicate, and the need to get other things done at the same time (cooking, inspecting the bookshelf). evocative illustrations to make the start of individual patterns easy to find. A person using a pattern language may not need to use all When reading through a complex pattern language for the relationships. The reader can easily recognize pattern sections and can tell at a glance how written with Skippable Sections; a reader could flip through the language A pattern language is a structured method of describing good design practices within a particular domain. This is what The following tables summarize the patterns in this pattern language Name by which it can be known and referenced. Special thanks to the UIUC Patterns In Design Patterns, the Resulting Context Few patterns live in isolation. The introduction of this pattern Example. A simple message is more likely to be understood correctly. Table 2: Pattern Naming and Referencing Patterns. using this reduced list. Target Audience. facilitate straightforward implementation? References to Patterns to cite the related patterns. How do you share a recurring solution to a problem with others The patterns in this section apply to all elements of a pattern or pattern Solution: The proposed solution to the problem. A long-winded pattern description may cause a reader to writing would claim to satisfy this phrase. When design is done by a team, pattern names will form a vocabulary they can share. These patterns can never be designed or built in one fell swoop - but patient piecemeal growth, designed in such a way that every individual act is always helping to create or generate these larger global patterns, will, slowly and surely, over the years, make a community that has these global patterns in it. mandatory elements?
