Small order Open Pandora's magic box-this is a seriesArticleThese articles do not really tell Pandora MM's story about opening the Magic Box. These are technical articles. They are to use real cases to describe the design process of software systems. The real case used in this article is the lottery system in the web game project. The lottery system is relatively independent and involves a few technical te

The original business process platform approval sheet uses the idea of horizontal table vertical storage, where the data for the business forms used by all processes exists in a physical table, and each data record in the table contains the field information for the column definition and value,column, defined by the definition table. This approach is implemented, it is necessary to use code for data assembly, more cumbersome. When the form is large, t

According to the 2013 record, about 80,000,000,000 mobile apps have been downloaded and the number is expected to double in the next four years. Although the number of app downloads is increasing, the number of users is decreasing. Such a large number of apps are competing for the user's energy, which is bound to lead to a decrease in user time for each app. This is a big problem for mobile apps that require new users to register. There is an increasingly common phenomenon: registering fatigue-

Through the analysis and design of the first two texts, we have been able to build an aggregation SDK service side that can support multi-game multi-channel, but this is just a simplified model in idealized state. If the logic of the access channel is built according to the idealized simplification process, then for the payment request, we can simplify the steps as follows: The game client creates

I recently read "Uml Toolkit" (Chinese name: "Uml tools", Electronic Industry Press) and have a better understanding of the design and development process of Uml 2.0 and MDA-based application systems, after reading the second article, I will summarize the following development modes that may be suitable for small and medium systems. Case-driven development mode: 1. Collect and discuss requirements (communi

Planning | backstage | design | website Construction First, the website planning stage This stage is mainly the function of the site, target audience, content, column planning. During this period, regular communication will be conducted with the relevant leaders. First of all, you must be the overall planning of the site clearly, and then to absorb other people's suggestions. The process of absorbing other

For Java multi-process communication, I am afraid the most used is socket. Of course, there are various other protocols, such as RMI and shared memory. Here we will not talk about the three, but about the simple Stream Transfer between parent and child processes in Java. Java does not clearly define some process-related APIs, and there is very little content in this regard, unlike C/C ++ directly using the

enrich your app with tools like push, map, social sharing, third-party login, and more in the Devstore platform. The use of third-party services to enrich their work is a good way to borrow, do not miss, usually to develop the habit of collecting platforms, such as tools platform, learning and communication platform, to develop and summarize the integration of resources will be a good habit of the benefit of life.3. Function Realization --The app project coding stageThe app's approximate interf

implemented by the CMD parameter, which defines 7 different operations in the header file sem.h, which can be used as reference in the actual programming.The SEMOP function automatically executes an array of operations on the semaphore set.int semop (int semid, struct sembuf semoparray[], size_t nops);Semoparray is a pointer to an array of semaphore operations. NOPS Specifies the number of operations in the array.Below, let's look at a specific example, it creates a specific IPC structure of th

) The parent process uses the WAIT4 () system to query whether the child process is terminated.Thread of execution: a thread, an object that is active in a process, each with a separate program counter, a process stack, and a set of process registers.2.

The home page is not a navigation process, but a process with special features, such as posting, posting, transferring money, charging, shopping, etc. you do not need to go to Weibo, Post, know, e-mall, blog, and other pages to complete these operations, instead, you can directly call the relevant processes on the home page to complete these operations in a non-contact manner. The

1. What is the Guardian process?The daemon, which is often said to be Daemon (ELF), is a service process in Linux. It is characterized by:Do not occupy the control terminal (running in the background)Independent of the control terminal (there is no corresponding TTY using command Ps-aux view)Periodic operationExample: SMBDNote L: When running the executable program, add , which means to run in the backgroun

How can you design a good and excellent website? Very simple question, but the lack of this system professional process is not. Now, let me just say the process of making this site. After all, the web design has been nearly two years, there are some experience. :) Early I wanted to do a website like this, but has not m

whether mode needs to be switched and then calls: Switchmode (): This is a coroutine, which calls loadmodefrommodeswitch (). Its core is to call loadmode (); Directly call loadmode () Loadmode () function, mainly based on the current mode, call loadscene (); The loadscene () function is called mainly:Application. loadleveladditiveasync (this. scenename ); This completes the scenario switching. OK. Through the above analysis, we have a general understanding of the game startup

Atitit Design Patterns and the relationship between the algorithm and the process1.1. Design Pattern is the algorithm is the process , different aspects of different views, abstract methods and the illusion caused by different. Software is built into the design pattern. It can also be said that the algorithm accumula

payment and the loan becomes redundant. Because the loan-number attribute shared by payment and loan defines an implicit link. Special/deductive During the top-down design process, a subset of the entity set with special properties is determined. These subsets become lower-level entity sets, which have special attributes or participate in special connections. Represented by a triangle with an ISA tag

The Web page is through the visual element compelling and realizes the information content transmission, in order to maximize the visual communication function of the Web page, so that the network truly becomes readable and strong and novel media, the design of Web pages must adapt to the psychological and physiological characteristics of people's visual flow, which determines the relationship and order of various visual elements. Therefore, we should

[Thanks to Terminator for posting this article] Next, let's start to look at the software design process of the input subsystem. When I read it, I also sorted out the relevant APIs in the design code, and detailed the Code Implementation of the input subsystem in the next article.Input subsystem software design

needs of the product design side, in fact, precisely because the product design side has the inevitable, inevitable needs (the need to verify the material to identify the authenticity of the shop, the need for online testing to ensure the quality of shopkeepers), product flow and experience is sure there will be a heavy step or a few steps, at this time, should be the light step in front, Let the user do i
