How to draw UML activity diagram

Scott W. Ambler
UML activity diagram of a single operation or method of recording the logic of a single user case, or a single business process logic. To create a UML activity diagram, you need to repeatedly perform the following steps.
The first step, define the scope of the activity diagram should first define what you want to model. Force a single user case? Part of a user case? A case of multiple user business processes? Single method of a class? Once you define your scope of the plan, you should be at the top, add a label with a label specifying the plan's title and the only identifier. You may also want to include the time and even on the map name.
The second step, add the start and end points of each activity diagram has a starting point and end point, so you have to add them right away. In the "UML essence" (UML Distilled) (see references), Fowler and Scott that the end is optional. Sometimes an event is just a simple end, if this is the case, indicating the only change is to an end point is also harmless. Thus, when other people read your map, he or she knows you have to consider how to withdraw from these activities.
The third step is to add activities if you are a user case modeling, for each role (actor) issued a major step in the introduction of an activity (this activity may include initial step, with initial steps of the system response to any steps). If you are on a high-level business process modeling, on the introduction of an activity for each major process, typically a user or user case package case. Finally, if you are on a method of modeling, then the introduction of an activity which is common. The fourth step is to add activity changes between my style is always an activity should be out, even if it is changed to an ending point. Once an activity has multiple changes, you must be the appropriate label for each change.
The fifth step, add the decision-making point sometimes, you need to make modeling a decision-making logic. There may be need to examine certain matters or certain matters more. It should be noted that the use of decision points is optional. For example, in Figure 1, I can just simply "accept" and "reject" two changes directly to the "in college enrollment (Enroll in University)" activities.
Step six, identify parallel activities between the two activities when there is no direct link between, and they are required before the event at the end of the third, then they can run in parallel. In Figure 1, you see it is possible to "participate in a brief description (attend overview)" and "Application Seminar (enroll in seminars)" can be carried out in any order, but they had to in your completed before the end of the process.

1, information sharing, the real integration of data

For the staff data, simply enter a Philips Zhuhai can be other modules in the system can be shared. In payroll, the system can automatically read the staff from the personnel module entry date, position, rank, etc. need to participate in wage information.

At the same time, the system can automatically read the attendance and leave the module staff late this month, leave early, without pay, leave and other information, staff from the evaluation module to read the assessment results, which greatly simplifies the payroll and personnel departments of the original data collection complicated work, and guarantee the accuracy and timeliness of information, preserved a complete historical record.

Three 3G licenses which Zhang's most "money" way?

January 7, 2009, is a good day to be remembered. Because, on this day, repeated calls to the three 3G licenses issued, and finally to China's wireless communications technology with the world shoulder to shoulder, especially with independent intellectual property rights of 3G standard - TD-SCDMA, more is the global wireless communications technology in the pride. However, the more worthy of attention is fierce competition in the market economy and complex political environment in the world, "three 3G licenses, which Zhang's most have 'the money' way?."

By the International Telecommunication Union (ITU) in 2000 identified three major 3G standards: W-CDMA - also known as WCDMA, is Europe's proposed broadband CDMA technology; CDMA2000 - by the narrowband CDMA (CDMA IS95) technology development to the wideband CDMA technology, Qualcomm North America, led by the proposed 3G technology; TD-SCDMA - all known as Time Division - Synchronous CDMA (time division synchronous CDMA), developed by the 3G standard in China alone.

It is learned, 3G licenses is also known as "wireless communications and the Internet, combined with a new generation of multimedia mobile communications system operating license." In other words, only with the 3G licenses wireless communications ventures, to business and technical standards for 3G wireless communications services. In the three 3G licenses in China Fa Fang, China Mobile was independently developed by China's TD-SCDMA technical standards, China Telecom acquired from QUALCOMM CDMA2000 in North America Corporation Orientation Tichu technical standards, China Unicom made available in Europe wideband CDMA technology standard. Undeniably, these three 3G technology standard, is to keep pace with today's internationally recognized standard for wireless communications technology, in essence, may not have "distinction or" parts, there is fair competition, equality.

However, the reason I put forward the "three 3G licenses, which Zhang's most 'money' way" issue, not because of what the three existing 3G technology standard question, nor is it our three business viability of wireless communications there is little doubt, but with an alternative perspective of development thinking in the course of the future, there may be unexpected "external change" and allow us to "three 3G licenses, which Zhang's most 'money' way" and confused. In my opinion, should be noted that in today's global economic integration, market economy, the three will inevitably exist between the 3G technology standard for the user's "selective competition" and "service competition", particularly in China The large wireless communications market environment, competition for the user inevitably is very intense. Therefore, from the moment the three major operators in China, "User share" there is no doubt that China Mobile as the "User share" (80%) of the great advantages, it was independently developed by China TD -SCDMA technology standard, also laid this license is the most "money" passers-by license. Because such an arrangement not only to maximize the development of China's own TD-SCDMA technology standard gain maximum economic benefit, more importantly, also to maximize communication technology for Chinese users to get security. Thus, this is our answer the "why should this TD-SCDMA license to China Mobile" reasons.

Of course, if the above statements is difficult to explain the development of China's own TD-SCDMA this license the most "money" way, we might then predict from a political perspective this TD-SCDMA license the most "money" in other applications. As we all know, China is a "political principle" a very strong country, in which patriotism and nationalism (including the ultra-nationalist) sentiments, may break out at any time. Do not you see, in the past because of the Sino-Japanese Relations (Koizumi's Yasukuni visits) into a trough, the Chinese community broke out the "boycott" the strong "passion"; Do not you see, in the past because of the Sino-French relations (France humiliated and the Olympic flame Sarkozy met the Dalai Lama) into a trough, the Chinese community broke out the "boycott France goods" strong "voice"; ... .... The history has to tell us, who can guarantee that day will not be at the political level "diplomatic reasons" happened "to resist the 3G WCDMA standard in Europe" or "against the United States of 3G CDMA2000 standard" of patriotism or nationalism "aspirations" what? starting from such a fear, can alone can not explain the development of China's TD-SCDMA technology standard is the most secure? Do not prove this license TD-SCDMA is the most "money" way of licenses?

In short, the "three 3G licenses, which Zhang's most 'money' way", the only stand in the situation in China can see clearly and be able to find the answer. Remember January 7, 2009, China entered the 3G era, China into a 3G future, like we live in a more right!

Dual disc engraved with me

Author: Zhou Dongfei

Do not know if you have not noticed, a lot of study and class are often advertised CD-ROM, CD-ROM that call themselves players, computer "dual-use CD-ROM." Wonderful it, this CD-ROM in real life but very useful, want to learn a moment? Follow me!

Hardware Requirements I do not have winded the bar, if you do not have burners, this article can first cut, left to be run. Software recommended Nero5, in the burning area does not know it almost does not, you can easily download to its Chinese version.

"Dual Disc" in substance, is a VCD compatible format and common data formats of mixed mode. Most burning software have given a "music CD with the data" mixed mode, but no "VCD and data" mixed mode. It does not matter, we burn a normal VCD from the beginning. Assumptions needed to burn MPG files and data files are ready to pay attention to the size of the two combined can not exceed 650MB. Start Nero5, into the burn VCD interface (Figure 1). In order to facilitate the following presentation, we assume that: 鈶?the hard disk data area, 鈶?for the CD-ROM data area, 鈶?for the video track area.



From the right side of "hard data area" to find you want to burn the MPG file, drag and drop by the order to "video track area", be careful not to put "CD-ROM data area". A new document will be out of the window, on the MPG file to verify treatment. Disposed of, the top left window, right-click "New" CD-ROM icon in the pop-up menu, select "Properties", on the detailed properties of the disc VCD set. For example, you can create a beautiful VCD Start menu.

Add VCD set is completed, we can start adding data files. When I first burn a VCD with Nero, I use it specifically related to a window to the folder listed is incorrect, who cares what these folders? In fact, this is the Nero of the Superman of the Department. If you can not see CD-ROM content, which will not be able to add data files. From "hard disk data area" to choose your data file ready, drop them to the "CD-ROM Data Area" in the. Note that one should not put "video track area", the second is not to put "CD-ROM data area" VCD relevant folder. Data files can be a good multimedia presentation documents the development, but also can be any common data file. If you need to have self-running CD-ROM features, you can also write a autorun.inf file on the CD-ROM root directory. These are not elaborate, please refer to related information.

Well, choosing a burner, start burning it. To ensure that the video image quality, the best use of low-speed recording. Upon completion of the first try on the DVD machine, and then back into the computer CD-ROM drive to try, is not a modern discovery of the "dual-use CD-ROM?"
