Scalability for software architecture is its ability to handle - -3 -00:00:06,660 --> 00:00:09,320 -the growth of the software system. For example, for a - -4 -00:00:09,320 --> 00:00:12,610 -web based system, scalability could be the ability to handle - -5 -00:00:12,610 --> 00:00:15,620 -a larger workload by adding new servers to the system. - -6 -00:00:15,620 --> 00:00:19,508 -Scalability is therefore an important characteristic of a software architecture, - -7 -00:00:19,508 --> 00:00:21,938 -especially for the kinds of systems that can grow over - -8 -00:00:21,938 --> 00:00:24,990 -time. So, we're going to mark it as an ideal characteristic. - -9 -00:00:24,990 --> 00:00:27,901 -Cohesion is a measure of how strongly related are - -10 -00:00:27,901 --> 00:00:30,920 -the elements of a module. Clearly, we should shoot - -11 -00:00:30,920 --> 00:00:33,760 -for high and not low cohesion when developing a - -12 -00:00:33,760 --> 00:00:37,100 -system. We want to develop modules whose elements cooperate to - -13 -00:00:37,100 --> 00:00:40,480 -provide the specific piece of functionality rather than modules - -14 -00:00:40,480 --> 00:00:43,410 -consisting of a bunch of elements that provide different - -15 -00:00:43,410 --> 00:00:47,040 -unrelated pieces of functionality. Therefor, low cohesion is definitely - -16 -00:00:47,040 --> 00:00:49,980 -not something that we want. We want high cohesion instead. - -17 -00:00:49,980 --> 00:00:53,040 -As for coupling, coupling is a concept related to cohesion - -18 -00:00:53,040 --> 00:00:55,070 -and is also a measure. In this case though, it - -19 -00:00:55,070 --> 00:00:58,130 -is a measure of how strongly related are the different - -20 -00:00:58,130 --> 00:01:01,830 -modules in a system. Low coupling, which is often correlated with - -21 -00:01:01,830 --> 00:01:05,570 -high cohesion, is an important and ideal characteristic of a - -22 -00:01:05,570 --> 00:01:08,660 -software architecture as it indicates that the different modules in - -23 -00:01:08,660 --> 00:01:12,220 -the system are independent from one another. Each module provides - -24 -00:01:12,220 --> 00:01:15,300 -a specific piece of functionality and it can provide it without - -25 -00:01:15,300 --> 00:01:17,530 -relying too much on other modules. - -26 -00:01:17,530 --> 00:01:19,960 -Basically, systems characterized by low coupling - -27 -00:01:19,960 --> 00:01:23,330 -and high cohesion, are systems that are easier to understand, and to maintain. -- cgit 1.4.1
