38、'engineer" or practice hsoftware engineering* in the usa, beginning in 2013, the path for licensure of software engineers will become a reality. as with the other engineering disciplines, the requirements consist of earning an abet accredited bachelor degree in software engineering (or any

39、non-abet degree and ncees credentials evaluation), passing the fundamentals of engineering exam, having at least four years of demonstrably relevant experience, and passing the software engineering pe exam. in some states, such as florida, texas, washington, and other, software developers cannot use

40、 the title nprofessional engineern unless they are licensed professional engineers who have passed the pe exam and possess a valid license to practicethis license has to be periodically renewed, which is known as continuous education, to ensure engineers are kept up to date with latest techniques an

41、d safest practicesthe ieee computer society and the acm, the two main us-based professional organizations of software engineering, publish guides to the profession of software engineering. the ieee's guide to the software engineering body of knowledge 2004 version, or swebok, defines the field a

43、 engineers holding jobs in the us； in the same time period there were some 1.4 million practitioners employed in the u.s. in all other engineering disciplines combined due to its relative newness as a field of study, formal education in software engineering is often taught as part of a computer scie

45、rs some organizations have specialists to perform each of the tasks in the software development process other organizations require software engineers to do many or all of them in large projects, people may specialize inonly one role in small projects, people may dll several or all roles at the same

46、 time. specializations include: in industry (analysts, architects, developers, testers, technical support, middleware analysts, managers) and in academia (educators, researchers)most software engineers and programmers work 40 hours a week, but about 15 percent of software engineers and 11 percent of

47、 programmers worked more than 50 hours a week in 2008 injuries in these occupations are rare however, like other workers who spend long periods in front of a computer terminal typing at a keyboard, engineers and programmers are susceptible to eyestrain, back discomfort, and hand and wrist problems s

48、uch as carpal tunnel syndrome the held's future looks bright according to money magazine and s, which rated software engineer as the best job in the united states in 2006 in 2012, software engineering was again ranked as the best job in the united states, this time by careerc it seems that the c

49、omputer science and the software engineering these two studies are similar to each other. but in fact, they have many differences we can see this fact apparently from several aspects, as what we will discuss in the following:1、final destination:(a)、software engineering: software engineering "s

50、final destination is constructing the soft wares which users really need under the main restrictions of time, resource and personnel. it pays more attention on the planning process of constructing, the analyzing of the needs of users, but not on the researching process(b)、computer science: computer

51、science 4s final destination is to explore the correct calculation methods and also modeling methods, in order to improve the calculation theories and methods itself. ifs a circulating process which is of high efficiency from its destination we can see the content and the main way.2、products:(a) >

52、; software engineering: soft wares eg office bag and compiler. there are many kinds of software products, mainly divided into computer system software, application software, practical application mobile phone software these several different parts(b) 、computer science: problems about different sorts

53、 of algorithm to solve the specific problems much easier(e.g hilfs sorting ranking) and some abstract problem (e.g problem about philosophers9 having meals, a very interesting problem). so as we can see in the present society, these products are related to calculation itself to a great degree.3、spee

54、d and timetable:(a) 、software engineering: like a plan has its own time planning, all software projects also have specific progress and timetable to guarantee that the process can be on smoothly and quickly.in this standard way, the process of software engineering can be norm and of high efficiency.

55、(b) 、computer science: researching projects often doitt have a progress set before the beginning or the limit of timetable it is a vary flexible and free study.so we can see many scientists and mathematicians exploring something they enjoy from the bottom of their hearts for the lifetime.4、focus:(a)

56、> software engineering: this study pay more attention on how to realize the value for users it cares the users9 benefit most and first.(b)、computer science: the software theory in the computer science focus on the running principles of the software itself. for instance, the complexity of the time

57、, complexity of the space and the correctness of the algorithm computer science is very strict about the root theories, ifs very strictly required5、degree of the change along the development:(a)、software engineering: as the continuous change of the technology and the demand of software users, people

58、 who explore the new software must adjust his exploring in no time to fit the present demand to take us as an example this process just likes us, these college fresh men, after we have entered the college this new big world which we are not familiar with, we have to adjust ourselves quickly to accus

59、tomed to the new environment and try to develop our abilities to bring this world a big and good change at the same time, software engineering itself is in the continuous changing it is a double direction process of high efficiency(b)、computer science: software engineering itself is also in the development. the correct methods which aim to s
