Software design is the phase - -3 -00:00:06,080 --> 00:00:09,030 -where software requirements are analyzed in order to produce - -4 -00:00:09,030 --> 00:00:11,500 -a description of the internal structure and organization of - -5 -00:00:11,500 --> 00:00:13,900 -the system. And this description will serve as the - -6 -00:00:13,900 --> 00:00:17,550 -basis for the construction of the actual system. Traditionally, - -7 -00:00:17,550 --> 00:00:20,020 -the software design phase consists of a series of - -8 -00:00:20,020 --> 00:00:25,360 -design activities. Which normally consists of the architectural design phase, - -9 -00:00:25,360 --> 00:00:27,880 -the abstract specification, interface design, - -10 -00:00:27,880 --> 00:00:30,010 -component design, data structure and - -11 -00:00:30,010 --> 00:00:33,230 -algorithm design. And notice that this is just a possible list - -12 -00:00:33,230 --> 00:00:35,820 -of activities. But you can also characterize design activities in - -13 -00:00:35,820 --> 00:00:38,550 -many different ways. And if you're looking at different books, and - -14 -00:00:38,550 --> 00:00:41,800 -different sources, you might find different activities described. But the - -15 -00:00:41,800 --> 00:00:44,500 -core idea, the important point is that we go from sort - -16 -00:00:44,500 --> 00:00:46,940 -of a high-level view of the system, which is the - -17 -00:00:46,940 --> 00:00:50,770 -architectural design, to a low-level view, which is the algorithm design. - -18 -00:00:50,770 --> 00:00:53,100 -And these activities result in a set of design - -19 -00:00:53,100 --> 00:00:56,810 -products, which describe various characteristics of the system. For - -20 -00:00:56,810 --> 00:00:59,770 -example, they describe the architecture of the system, so - -21 -00:00:59,770 --> 00:01:02,890 -how the system is decomposed and organized into components, the - -22 -00:01:02,890 --> 00:01:06,630 -interfaces between these components. They also describe these components - -23 -00:01:06,630 --> 00:01:09,030 -into a level of details that is suitable for - -24 -00:01:09,030 --> 00:01:12,470 -allowing their construction. We will discuss the details of - -25 -00:01:12,470 --> 00:01:16,130 -software design and talk extensively about these different actives and - -26 -00:01:16,130 --> 00:01:19,200 -these different products in the third mini course of this class. |
