The first one is from Dewayne Perry - -5 -00:00:11,030 --> 00:00:13,990 -and Alex Wolf. And they define a software architecture - -6 -00:00:13,990 --> 00:00:17,940 -as elements, form and rationale. In this definition, the - -7 -00:00:17,940 --> 00:00:21,300 -elements are the what, which means the processes, data, - -8 -00:00:21,300 --> 00:00:25,430 -and connectors that compose a software architecture. The form - -9 -00:00:25,430 --> 00:00:27,780 -is the how, the set of properties of - -10 -00:00:27,780 --> 00:00:32,030 -in relationships among these elements. And, finally, the rationale - -11 -00:00:32,030 --> 00:00:35,390 -is the why, the justification for the elements and - -12 -00:00:35,390 --> 00:00:38,440 -their relationships. The second definition I want to use - -13 -00:00:38,440 --> 00:00:40,710 -is from Mary Shaw and David Garland. And - -14 -00:00:40,710 --> 00:00:43,480 -they defined a software architecture as a level of - -15 -00:00:43,480 --> 00:00:47,300 -design that involves four main things, a description of - -16 -00:00:47,300 --> 00:00:50,860 -elements from which these systems are built, the interactions - -17 -00:00:50,860 --> 00:00:54,800 -among those elements, the patterns that guide their composition, and - -18 -00:00:54,800 --> 00:00:58,320 -finally, the constraints on these patterns. As you can see, these - -19 -00:00:58,320 --> 00:01:01,420 -definitions are fairly similar and there are many more alternative - -20 -00:01:01,420 --> 00:01:04,870 -definitions of software architecture. In fact, if we try to search - -21 -00:01:04,870 --> 00:01:08,540 -the term software architecture, we get over two million entries. - -22 -00:01:08,540 --> 00:01:10,670 -And if we look at the images in the results of - -23 -00:01:10,670 --> 00:01:13,110 -the search this is what we get. And I like this - -24 -00:01:13,110 --> 00:01:16,120 -sort of graphical depiction because it gives you a clear idea - -25 -00:01:16,120 --> 00:01:19,300 -the software architecture are prevalent concept, given the number of - -26 -00:01:19,300 --> 00:01:22,600 -results. But they also show you clearly, that software architecture are - -27 -00:01:22,600 --> 00:01:25,550 -complex entities, if you look at some of these pictures. - -28 -00:01:25,550 --> 00:01:28,930 -And ultimately, they show that software architecture are presented in all - -29 -00:01:28,930 --> 00:01:31,700 -kinds of ways including in 3D, if you look at this - -30 -00:01:31,700 --> 00:01:34,970 -picture. We cannot clearly cover all of these definitions in one - -31 -00:01:34,970 --> 00:01:37,340 -lesson. So what I will do instead, is to introduce - -32 -00:01:37,340 --> 00:01:40,750 -a very general definition that encompasses most of the existing ones. -- cgit 1.4.1
