+00:00:00,150 --> 00:00:03,200

+But with so many patterns, how do we choose a pattern? So

+

+2

+00:00:03,200 --> 00:00:05,970

+this is a possible approach that you can follow. First of all, you

+

+3

+00:00:05,970 --> 00:00:09,140

+want to make sure that you understand your design context. You understand

+

+4

+00:00:09,140 --> 00:00:12,800

+what you're designing and what are the issues involved with this design. What

+

+5

+00:00:12,800 --> 00:00:15,200

+are the problems that you need to solve. At this point, you

+

+6

+00:00:15,200 --> 00:00:17,160

+can examine the patterns catalog, or,if

+

+7

+00:00:17,160 --> 00:00:18,750

+you're already familiar with the catalog, just

+

+8

+00:00:18,750 --> 00:00:22,430

+think about the possible patterns that you could use. Once you identify

+

+9

+00:00:22,430 --> 00:00:25,440

+the patterns that you can use, you also want to study them and

+

+10

+00:00:25,440 --> 00:00:29,090

+study the related patterns. So normally if you look at any pattern catalog,

+

+11

+00:00:29,090 --> 00:00:32,229

+for each pattern there will also be a list of related patterns. So

+

+12

+00:00:32,229 --> 00:00:35,010

+you can also look at those to see whether maybe some of those

+

+13

+00:00:35,010 --> 00:00:38,370

+might be more applicable. And finally, once you identify the pattern that you

+

+14

+00:00:38,370 --> 00:00:41,360

+think is appropriate, you will apply that pattern. When you do that, just

+

+15

+00:00:41,360 --> 00:00:44,850

+be mindful that there are pitfalls in the use of patterns. One obvious

+

+16

+00:00:44,850 --> 00:00:47,490

+one is the fact that you might select the wrong pattern and make

+

+17

+00:00:47,490 --> 00:00:50,460

+your design worse instead of better. The second one is that if you

+

+18

+00:00:50,460 --> 00:00:52,560

+get too excited about patterns, then you

+

+19

+00:00:52,560 --> 00:00:54,850

+might be abusing patterns, so just using too

+

+20

+00:00:54,850 --> 00:00:56,370

+many patterns, and end up with a design

+

+21

+00:00:56,370 --> 00:00:58,980

+that is more complicated rather than less complicated.

+

+22

+00:00:58,980 --> 00:01:01,890

+So always be careful, spend the time to figure out which one is the right

+

+23

+00:01:01,890 --> 00:01:03,577

+pattern to apply, and make sure that you

+

+24

+00:01:03,577 --> 00:01:05,190

+don't use patterns that you don't actually need.
