System Analyper Exam Examination Test Method
Tian Junguo August 20, 2002
Recently, many readers came to the author asked the author to test the test method of the test I I, saying that the amount of test questions in the afternoon I was large, strong, and the corresponding tutoring material was also a phoenix righteous angle. It is really difficult to cope. Indeed, the system analyst exam is the road to the road, the afternoon test I, the author has been prepared for this year, recalling, there are some things - at least some personal opinions are different. To this end, the author once again read the test questions in the last 7 years, summoned some essence, settlement, and shared it with you. In the afternoon test, the computer application of the computer application, the analysis and design capacity of computer application system and the ability to analyze the problem, is a comprehensive investigation of the experience, knowledge and ability of the test. The author believes that from the perspective of the topic and the purpose of the topic, the second afternoon test I can be divided into the following seven types. 1. General knowledge of knowledge, systematic analysts must have extensive knowledge accumulation and work experience. There are many questions in the afternoon test I to directly examine the knowledge or experience of a certain aspect. This kind of topic is that it is usually accumulated and has a wide range of knowledge. It basically has no skill, knowing is very simple, I don't know if I am in a hurry. The only thing that the candidate can do is to avoid the topic of the knowledge field that does not have to hunt. Example 1.1998 Question 2 [Issues 1] and [Issues 2] [Question 1] Please use the text within 150 words to list the main advantages that the three-layer C / S software design can be used in the outline. For the advantages of the three-layer C / S software design, the candidates should also be known even if the background description of the inscribed is. That is: 1 indicates that the layer is simple (thin client), the version is released, the maintenance is convenient; 2 Intermediate logic is concentrated in the functional layer, only the intermediate logic can be changed during the upgrade; 3 data layer and represent layer isolation, safer . If the candidate does not have this knowledge accumulation, it has to analyze and extract from the mint. [Question 2] Please list a tool that supports three-layer C / S software development and briefly explains its functional implementation with 150 words. It seems that this problem is very simple, supporting a lot of tools for three-level C / S software development, but four years ago, there must be many people can't listen out. Example 2.2000 Question 1 [Question 2] Please use 100 words to briefly explain, what is the benefits of enterprise application integration? Ask the COM mode for the benefits of enterprise application integration, usually be good at accumulating friends, have already noticed: 1 Realize the component-level sharing of the entire enterprise business logic and application services; 2 eliminate repetitive logic, optimize processing; 3 adapt to environmental changes Flexible and convenient, the cost of development integration is short-term; 4 Application services are easy to manage. In fact, componentization is the dream of software developers. I hope that software development is as convenient, fast and repeatedly using the previous labor results like stacked wood. The candidate knows this, and it is natural to answer the benefits of componentization. Example 3.1999 Question 3 [Issue 3] According to your development of OA or MIS system, please include a class of popular platforms for developing workflow based OA systems. Software or tools, including access requirements for relational databases.
This is a typical knowledge experience question and answer question, and friends who have used Lotus Notes / Domino are not difficult to answer this question. Second, the identification analysis class is correct to identify the essential quality of the system analyst. This is because system analysts tend to be experts believed to be a computer application technology. As an expert, it is of course clear, which is not enough, which opinions It should be adopted actively. The discrimination analysis is to examine this ability. The discrimination analysis class is almost every year. Typical outcomes is to give more than ten discussion about a certain field or a technology, please find out which inappropriate description and explains. From the topic development situation in recent years, such topics have evolved into a question, and the candidates want to avoid them. Answer this type of topic, first of all, the respondents need to be based on solid theoretical foundations and rich practical experience, and can make a multi-angle understanding of a certain field or a certain technology. Second, there is a need for a certain language understanding ability and analysis capabilities. Third, the concise point to point out inappropriately, it also requires a deeper language to express efforts. When you can't find an inappropriate description for a while, you can use a way one by time, first find the absolutely correct description, and then make a reason to analyze a doubt, listed that you are not right. The reason, in order to convince yourself, find out that the doubts or can be determined is a wrong description. Example 4.1999 Questions [Issues 1] The question of the problem of the group has been analyzed in recent years in recent years, and the Group's Old President has presided over the discussion of software engineering management issues. opinion. It is required to find that three are incorrect or inappropriate, please point out the serial number and use 50 words to briefly explain the reason. This is a problem with software project management. Some doubts will be found with a scrub-by-one exclusion method. For example: (5) use more advanced operating systems, work platforms, and development tools to greatly improve software development efficiency, fundamentally prevent and solve the software development issues found in the summary in summary. "From fundamentally prevented and solved" this method, it is definitely extreme, excessively emphasized the role of tools, and ignoring the importance of human quality and project management, it is obviously unfolded. It is like advocating the computer to replace the human brain. We can shorten the travel time, but there is no good flight scheduling and control, you may be difficult to protect your life. The same reason: (6) The use of object-oriented (oo) technology can ensure the needs of team development in cross-platform complex environments, thereby fundamentally exempting the troubles of software engineering management, and can also fundamentally alleviate Li Li Software development issues found. Say "object-oriented technology, can fundamentally exempt the troubles of software engineering management" Naturally wrong. Therefore, the description is an absolute expression, generally should be particularly concerned, often wrong. (7) The software development project has not been completed and forced to cancel. It is nothing more than two categories: First, the user's demand is too frequent or high, and the other is the quality of software developers that cannot adapt to the project requirements. It also used the word "no non-", only emphasized the importance of demand changes and personnel quality, and ignored software engineering management. In fact, there is an authoritative survey indicate that the failure of software projects can be summed up as four reasons: the reasons for project organization, lack of demand management, lack of planning and control and estimation errors.
Example 5.2000 Question 1 [Issues In recent years, based on object-oriented "component" (also known as component) technology has developed rapidly, especially in the distributed network application environment development And the integration of the application has begun to use a wide range of components techniques. The information department of a company proposes some of the following opinions: ... (a total of 11) [Problem 1] Three of the above-mentioned narratives are incorrect or inappropriate, please point out the serial number, and use 50 words Brief explanation of text. This question has a certain difficulty because the topic has conducted a large inventory of various manufacturers and different standards COM technology, requiring the respondents to have a comprehensive understanding and certain experience of COM technology. But carefully scrutinize, not terrible, with some basic experiences and knowledge, or it is not difficult to identify the error. (4) Microsoft companies launched COM / DCOM / COM currently have the most large number of users, which is due to their development tools, can be developed in multiple languages and widely used in a variety of different platforms. Experience tells us that Microsoft products are generally not easy to compatibility with UNIX platforms, while others' products, usually meet with Microsoft platform, have NT version or Windows. (5) The EJB (Enterprise JavaBeans) launched by Sun is basically based on the Java language. It is relatively simple to support a variety of platforms and has the most abundant third-party development tools and products. EJB is very good, why don't we use not much? Still because there is a lack of third-party development tools and product support. (10) Component library or component system as a product, has versatility and reuse. Generality refers to each of the components should have a wide range of applications, ie, it is necessary to use in various applications immediately. If you have some ActiveX in Delphi, you will not agree with the above views. The application in different environments is specialized and customized. Third, comparative analysis classes have more identification, and different solutions can be compared to separate the advantages and disadvantages, and a good solution is often a variety of solutions. Comparative analysis is an indispensable method in system analysis. The proportion of such test questions in the afternoon I test is very large. Example 6.1995 Test 1 [Issues 1] and [Issues 2] There are two implementations of "batch work" in a C / S structure information system: centralized processing schemes and decentralized processing schemes. [Question 1] Please use 80 words to briefly explain the disadvantages of centralized processing schemes and decentralized processing schemes, respectively. The best way to answer this class is to read the background of the topic and the narrative of two different programs in the topic. It is best to find out which distinct features of the two programs and each other, it is best to list the extreme cases of two programs. The comparison can make a concise list: centralized processing is to focus on the job request to the information administrator, and the decentralized processing is to submit a handling job by each client at any time. It is not difficult to see that the disadvantage of the centralized style is that there are too many tasks when the information administrator processes, forming bottlenecks, network load weight; distributed disadvantages is that all users are directly operating directly, any user's mistake will affect the performance of the entire system . [Question 2] Xiao University proposes a combination of dispersion-centralized processing, and can achieve the effect of making a long-term remediation, please briefly explain the idea of the program.
It is obviously a compromise of two programs, partially concentrated (such as sectoral), and is submitted by multiple administrators. Concentrate to the domain controller, triggered by the domain controller is also a good way. Example 7.1999 Question II [Issue 1] Requirements Significant Differences between Treatment Process Function Compared to the original Layer C / S system based on the three-layer C / S system based on the original Layer C / S system. Do not consider the topic background, we know the difference between the two is that the three layers are more abstract out of the original two-layer, and then the figure given in the topic is combined, the correct answer is not difficult. Example 8.1998 Test Questions Dry section describes the characteristics of traditional distributed control systems (DCs) and fieldbus control systems (FCS) on behalf of the international development direction. [Question 1] It seems that the novel FCS is far more than traditional DCS as many characteristics and strengths of appealing. However, most experts in the discussion believe that DCS is still the mainstream of application selection in power plant projects. Please briefly explain the reason. Obviously, the requirements of the topic pointed out that the FCS is less than DCS in this particular environment in the power plant. Read the trunk carefully, list the outstanding characteristics of FCS and DCS, you will notice: "Computer, communication, automatic control, and display in DCS system", "and" FCS are network communication technology, distribute In the meter instrument in the scene, the measurement control equipment is organically connected together. " Then, in the environment where the power plant is high, the vibration is high and the electromagnetic interference is used to use FCS, various instruments, and equipment can work properly. [Question 2] Question the remote intelligent I / O scheme and which main advantages compared to traditional DCS? Natural, and the FCS and DCS schemes are compromised, both FCS's advantages, and solve the problem of interference with various instruments and equipment in the power plant environment. Fourth, learn the application of temperature, knowing new, people always have the knowledge that has been mastered, by the knowledge, and understanding the differences in understanding the learning method of us. We learned MS SQL, and then learn Oracle and unconsciously compare the difference between the two. Today, all major giants are endless due to competition, software development tools and application platforms have emerged, and all major manufacturers have similar products similar to competitors, let us meet inexpensively, to be the IT industry station stable, more need to learn applications Ability is over. The best way to keep up with the situation is to be more different, quickly learn, follow up and put into application. This type of topic is very similar to the previous comparative analysis. Different, the focus of the problem focuses on the study of learning effects, requiring the respondents to learn, basicly grasp the new theory or method. Example 9.1999 Tests 5 Trunking section introduced a software development process advocated by Rational Software Company - "Rui Ge Model".
[Question 1] During the software development process of traditional discussion, the software project development process is described as a research and development period (R & D), the production period and the maintenance period, which is generally in the various stages in the management point of management of the Ruiji model. Corresponding relationship? "Swiss model" is a new software development process, but we can compare her with the traditional software development process we are familiar with. It is concluded that the start phase plus the planning phase is equivalent to the research and development period; the construction phase plus the transfer phase is equivalent to the production period; the evolutionary stage is equivalent to the maintenance period. The second question of this issue is "learning application" type: [Question 2] According to your development experience, in a medium-scale software project, the energy and time spent in the initial development period of management views What main measures can be used to reduce the proportion of this phase? By comparative learning, we know that the construction phase is equivalent to the design and development process in traditional software development, the design and development of traditional software development is a large amount of work, so the proportion of the construction phase in the Rui genus should also be large. Example 10.1995 The three questions of the three questions of the trials were first described with the external behavior of local telephone call events in a demand language processor (RLP). Then describe the SDL language developed by CCITT (specification and description language), and give the SDL language description diagram of the same local telephone call event. Question One and Issues Two are all learning applications. The problem is required to speculate on the meaning of the SDL mark, and the question 2 requires the contents of the SDL language description. The candidate is more likely to learn the SDL language according to the full description of the RLP, find out the commonality (or combined point), and the answer is easy. V. Scenario Reference This type of question requires that the subject will combine the scenarius described the topic and its actual development experience to speculate on a certain functional module or a certain part of a certain function in the scenario described. Coping such topics, must be careful to summarize the characteristics of the scenario itself described, and the various information revealed in the topic, but also to supplement some topics according to our previously similar project development experience, but often The lack of partial features. In fact, we often use this method in demand research. This type of topic also examines the ability to analyze design experience, considering the comprehensiveness of the problem and the ability to summarize literal needs. Example 11.2000 Questions III [Question 3] The question dry section describes some plans and envisions when a business is planning the Intranet of the company. [Question 3] What is the basic feature of the "Proxy Server" software listed in the above server software, please use 100 words to briefly explain. The respondents need to answer experience and topic requirements: should have internal users to access the Internet network, so that external users and internal users are isolated, security, traffic accounting and other functions. Example 12.1995 Question 2 [Issues 1] Requires the application to manipulate the management measures 1 and the content of management measures 2 in the disk space and user file management process. The information on the question is: "Disk space and user file management: including guarantee enough disk space, can protect user files, etc." This information tells us that management measures 1 and management measures 2 are to ensure disk space and Protecting files, but this is too much not specific, and still supports the usual accumulation of the need for the need. Example 13.1999 Questions 4 [Issue 2] The inscription of a medium-sized chemical raw material product is implemented in this manner in this way in this way. Related backgrounds.
[Question 2] Wang Kezi's initial planning program for its own chemical enterprises: (Application Scheme Module Figure) Please use 100 words to briefly list the main function of the System Initialization module in an outline method. Through the analysis of the subject, it is known that the functionality of the initialization portion has the following points: 1 Configuration and initiation of the address, channel, and signal of the capture front end. 2 Set the working mode of the measurement channel. 3 Host network, address, communication interface interrupt mode and work mode setting. 4 Network clock correction or report initiation, etc. It should be noted that [Issue 1] of the test 2 in 1994 also requested that the basic content of "Initialization Module" is also required, and "initialization" is visible. Example 14.2000 Question 5 [Issue 2] Do you think in this cost settlement and management system? Quot; Query cost data "can provide query function? Please use 100 words to read the text. Possible data retrieval means, according to the product, according to the year, monthly, press the workshop, according to the process, according to the part (material) query. Sixth, the problem that the analysis system analyst also encountered is a system Complex issues (or difficult symptoms) have analyzed to find out the real cause of the problem, or analyze the potential risks of a solution. The former is the cause of a certain symptom analysis problem, the latter is based on the existing existing The status analysis may have problems. The ability to solve problems or risk analysis is that the attack is not coming, it must be derived from the wide range of people. The rich experience can naturally be used by the crust into, and the experience is not enough to see others. It will be beneficial. Example 15.1995 test questions 5 questions describe some countermeasures for information security design (including 6) when developing personnel management information systems in a unit of personnel departments. Two examples have been made when discussing design principles Example 1 and Example 2 belong to what nature, how to avoid it. This is a typical design method potential risk analysis questions, readers to check the exam questions carefully. Example 16.1995 questions 2 [Question 2] When it comes to the design user's lock and release function, it is mentioned that a method can be made in the corresponding password field regardless of whether the user has set a password, and the corresponding password cannot be matched. The release of the lock-locked user can be done by deleting these additional LOCK flags. When Wang Gao workers are carefully reviewed this program, I found a latent risk. Please explain with 100 words in 100 words. Some experience in UNIX The reader will find that this one-knife-cut method is likely to cause the superuser password may also be locked. Example 17.1997 test questions 1 [Question 2] For a civil aviation online transaction with more than 1,000 client work sites In addition, in addition to the server is likely to become a bottleneck, configuration management and version control are relatively difficult, there will be some other difficulties. Please use the 80-word text to make a briefly based on the C / S platform-based civil aviation online business These possible difficulties of large systems. This topic requires analysis of these possible difficulties of civil aviation online transactions based on C / S platform, actually asking the shortcomings of traditional C / S structures. Working over more than 1,000 clients Site software installation, upgrade, maintenance and version distribution is naturally difficult. Seven, induction abstract class puts reality, the user needs of the natural language described in the natural language is a very deep foundation; The need for reasonable summation and classification is also a kind of hard work. There is no lack of such test questions in the exam questions. This topic requires higher abstract thinking ability and understanding. The author answered this problem is that abstract theoretical institution, combines some of your projects you have done, and exemplify the abstract things.
