A + +2 +00:00:02,350 --> 00:00:06,700 +software component is an architectural entity that encapsulates + +3 +00:00:06,700 --> 00:00:09,940 +a subset of the system's functionality and or + +4 +00:00:09,940 --> 00:00:13,180 +the system's data. So basically components typically provide + +5 +00:00:13,180 --> 00:00:16,100 +application specific services. In addition to that, a + +6 +00:00:16,100 --> 00:00:19,650 +software component also restricts access to that subset + +7 +00:00:19,650 --> 00:00:23,570 +via an explicitly defined interface. And, in addition, + +8 +00:00:23,570 --> 00:00:25,610 +which I'm not showing here, a component + +9 +00:00:25,610 --> 00:00:28,010 +can also have explicitly defined dependencies + +10 +00:00:28,010 --> 00:00:30,990 +on its required execution environment. In complex + +11 +00:00:30,990 --> 00:00:33,680 +systems, interactions might become more important and + +12 +00:00:33,680 --> 00:00:36,220 +challenging than functionality. And this is why + +13 +00:00:36,220 --> 00:00:40,000 +connectors are very important architectural elements. A + +14 +00:00:40,000 --> 00:00:42,935 +software connector is an architectural building block + +15 +00:00:42,935 --> 00:00:46,990 +tasked with effecting and regulating interactions among + +16 +00:00:46,990 --> 00:00:50,980 +components. So basically, connectors typically provide application + +17 +00:00:50,980 --> 00:00:54,610 +independent interaction facilities. And it's worth noting here + +18 +00:00:54,610 --> 00:00:57,530 +that in many software systems, connectors might simply be + +19 +00:00:57,530 --> 00:01:01,140 +procedure calls or shared data accesses. So all constants + +20 +00:01:01,140 --> 00:01:03,589 +that we're familiar with. But consider that much more + +21 +00:01:03,589 --> 00:01:06,690 +sophisticated and complex connectors are also possible. And + +22 +00:01:06,690 --> 00:01:10,310 +components and connectors are composed in a specific way + +23 +00:01:10,310 --> 00:01:13,510 +in a given system architecture to accomplish that system's + +24 +00:01:13,510 --> 00:01:17,400 +objective And this is expressed through an architectural configuration. + +25 +00:01:17,400 --> 00:01:21,070 +More precisely, an architectural configuration, or topology, is a + +26 +00:01:21,070 --> 00:01:25,630 +set of specific associations between the components and connectors + +27 +00:01:25,630 --> 00:01:28,380 +of a software system's architecture. So now, let's look + +28 +00:01:28,380 --> 00:01:30,880 +at an example that brings all of this together. |
