+1
+00:00:00,140 --> 00:00:02,320
+The last thing that I want to mention about class diagrams is
+
+2
+00:00:02,320 --> 00:00:05,830
+some creation tips. So something I know based on my experience and the
+
+3
+00:00:05,830 --> 00:00:09,300
+experience of others, I can recommend to do when creating a class
+
+4
+00:00:09,300 --> 00:00:12,780
+diagram. So the first tip is to understand the problem. So take the
+
+5
+00:00:12,780 --> 00:00:15,070
+time to look at the description of the system that you have
+
+6
+00:00:15,070 --> 00:00:18,500
+to build, to make sure that you understand the domain. That you understand
+
+7
+00:00:18,500 --> 00:00:21,230
+what you are supposed to build. Because that is going to save you
+
+8
+00:00:21,230 --> 00:00:25,550
+time later. It's going to help you identify from the beginning, a more relevant
+
+9
+00:00:25,550 --> 00:00:28,370
+set of entities in the description of the system. This
+
+10
+00:00:28,370 --> 00:00:30,730
+one might seem trivial but is very important to choose
+
+11
+00:00:30,730 --> 00:00:34,910
+good class names. Why? Because class names communicate the intent
+
+12
+00:00:34,910 --> 00:00:37,770
+of the class, and clarify what the class refers to. So
+
+13
+00:00:37,770 --> 00:00:40,510
+having a good class name allows you, makes it easier, to
+
+14
+00:00:40,510 --> 00:00:44,390
+create the mapping between the real-world object and the entities in
+
+15
+00:00:44,390 --> 00:00:46,610
+your model. And of course, it also makes it easier
+
+16
+00:00:46,610 --> 00:00:50,100
+to understand the system, after the system is built. Third tip,
+
+17
+00:00:50,100 --> 00:00:53,480
+concentrate on the what. So here, in the class diagram,
+
+18
+00:00:53,480 --> 00:00:57,390
+we're just representing the structure of the system. We're representing
+
+19
+00:00:57,390 --> 00:01:00,150
+what is in the system. What are the entities? What
+
+20
+00:01:00,150 --> 00:01:03,140
+are the characteristics of the entities? We are not focusing
+
+21
+00:01:03,140 --> 00:01:06,850
+at all, on how things are done. So, be careful.
+
+22
+00:01:06,850 --> 00:01:09,430
+Don’t think about the how, just think about the what.
+
+23
+00:01:09,430 --> 00:01:12,150
+Proceed in an itinerary way. So, start with a simple
+
+24
+00:01:12,150 --> 00:01:14,910
+diagram and refine it. There is no need to identify,
+
+25
+00:01:14,910 --> 00:01:17,650
+right away, all of the details of the system you need to
+
+26
+00:01:17,650 --> 00:01:21,570
+build. It is much easier to look at the description, identify an initial
+
+27
+00:01:21,570 --> 00:01:24,670
+rough class diagram and then refine it, because in this way, you'll
+
+28
+00:01:24,670 --> 00:01:27,650
+also gather more understanding of the system as you build it, and you'll
+
+29
+00:01:27,650 --> 00:01:30,670
+most likely end up with a better product at the end. And
+
+30
+00:01:30,670 --> 00:01:33,360
+if you proceed in this way, then make sure to refine until you
+
+31
+00:01:33,360 --> 00:01:36,920
+feel the class diagram is complete, until you feel that you represent
+
+32
+00:01:36,920 --> 00:01:39,960
+the system that you're supposed to build. So your final goal should be
+
+33
+00:01:39,960 --> 00:01:41,820
+to have a class diagram that is complete.
+
+34
+00:01:41,820 --> 00:01:43,870
+So it represents all of the relevant entities
+
+35
+00:01:43,870 --> 00:01:45,870
+in the system and their characteristics, and it's
+
+36
+00:01:45,870 --> 00:01:48,170
+correct so it represents them in the right way
