"The concept of design patterns was first introduced by Christopher Alexanderfor use in architecture and town planning. He realized that architects encounterd the same sorts of problems when engaged in the design of buildings and once an elegant architectural solution to these common problems was discovered, it could be repeated over and over again. In 1977, he wrote a book, published by the Oxford University Press, called “A Pattern Language”, in which he stated:

“Each pattern describes a problem which occurs over and over again in our environment, and then describes the core of the solution to that problem, in such a way that you can use this solution a million times over, without ever doing it the same way twice”

Conclusion:

Therefore a pattern-based system can be defined as a grid drawn over a specific structure where one specific block/section is selected and a pattern is created in that block which will then create a family and can then be applied to the rest of the grid without having to apply the pattern to each block individually.
