The complete process of developing an APP In recent years, driven by the market and policies, China's service outsourcing industry has developed rapidly, and the trend of intelligent service has emerged. With the increasing core business outsourcing activities, service outsourcers with professional skills, high added value and overall solutions have become the choice of more and more enterprises. How to become an industry leader in a highly competitive market environment? How to improve the development efficiency of APP? Zhengzhou Weifei takes you to understand "the complete development process of an APP". First, collecting requirements and analyzing requirements analysis is the most important link in the development process of an app project, and the success of APP development largely depends on it. The user demand analysis mentioned here refers to the combing of APP functions based on user needs. The target subjects are all users, "user-centered", not shouting slogans. Because the apps developed by many companies are used by users with needs, when combing the development needs of apps, we should not only understand the development needs of enterprises, but also understand the needs of users targeted by this enterprise. Finally, these requirements are sorted and classified, and a general functional framework of an APP is sorted out. In this process, don't interrupt the contact with users, try to ensure that there is no doubt, so as to avoid the cumbersome and inapplicable functions developed. Second, budget evaluation and cost setting Whether the project is developed by our own team or commissioned by a third-party company, it is very necessary to establish a perfect and quality requirements document. Investment demand documents can accurately estimate the investment budget of the project, and at the same time, these documents will help product managers, UI designers, technical developers and so on to understand the project and reduce possible mistakes in personnel communication. Third, the prototype design prototype design is similar to a sketch of an APP product. After in-depth user analysis, the sorted requirements are classified and sorted into functional modules, and a simple product prototype can be constructed by using these functional modules. Four. UI Visual Design Based on the product prototype, UI designers began to beautify the interface of APP, design the layout structure, control the design style according to the displayed content, make corresponding color matching, draw function menu icons, and design page elements for each area. During this period, it is necessary to constantly communicate and modify, and finally design all the interface renderings of the APP. V. Architecture design system architect is a person who needs to control the overall situation, understand local bottlenecks and give solutions according to specific business scenarios. Technical personnel who confirm and evaluate system requirements, give development specifications, build the core framework of system implementation, clarify technical details and solve major difficulties. Mainly concerned with the "technical realization" of the system. Therefore, he/she should be proficient in specific development platforms, languages and tools, and be able to give the most appropriate solutions for common application scenarios immediately. At the same time, he/she should know enough about his/her development team and be able to evaluate the cost of his/her team to achieve specific functional requirements. The system architect is responsible for designing the overall architecture of the system, considering every detail from requirements to design, grasping the whole project, and making the designed project as efficient as possible, easy to develop, convenient to maintain and simple to upgrade. The main task of an architect is not to write specific software programs, but to devote himself to a higher-level development framework. He must have a good understanding of development technology and good organizational and management skills. It can be said that the architect's work determines the success or failure of the whole software development project. The construction of intransitive verbs database arranges functional data processing according to the demand analysis, establishes a reasonable database table structure, optimizes data algorithms, improves data processing efficiency, and ensures the safety, accuracy, stability and timeliness of data during the use of APP. 7. The core process of developing an APP application on the server side is completed by the program on the server side, and the APP knowledge of the client side needs to send and receive data. Due to the limited hardware configuration and storage capacity of users' mobile devices, the core data processing process is all carried out by the server, which is the so-called cloud computing, and the server feeds back to the client APP after processing. Therefore, the program development on the server side is extremely important, and all functions need to be developed in strict accordance with the functions sorted out in the requirements analysis stage. Server development, especially Web development, basically deals with HTTP requests. According to the specific use, it can be divided into two types: web development and API interface development. 8. The developer of iOS/Android client develops the client according to the APP renderings, realizes the code of designing renderings, writes the interface of function calling, connects the server, and enables the data on the server to interact, so as to develop the client of APP consistent with the renderings. Nine. APP program test/comprehensive test of /QAAPP. This test simulates the problems that users may have under normal and abnormal use. Of course, you need to import the necessary data for testing, and constantly develop and fix errors. If it passes, it proves that the whole APP has been completed, and then the finished product is handed over to the user for trial. Arranging sufficient test time before the project goes online is an important guarantee for software quality. X. After uploading to the APP store to complete signature verification, the developed client APP program can be submitted and published to the APP Store. The iOS version of the APP is submitted to Apple's AppStore, and the Android version is submitted to major Android app stores in China. (PS: According to the current application in the Android market, you must provide proof of work with software ownership, that is, soft copy. In order not to affect the online time, it is recommended that all platform accounts and certificates that need to be used complete the application as soon as possible in the project synchronization or early stage. )XI。 Maintenance and update of APP. Maintain the app after it goes online, collect user feedback information, and fix the bugs in the app application in time. 1. Maintain the accounts of developers in major application markets, and update and maintain the accounts of developers in ios systems such as Apple Store and Android systems such as pea pods, Android Market, Wood Ant Market and 360 Market. 2. Update the next version, upgrade functions, add chapters, etc. According to the user feedback and product data analysis after the first version of app was launched. Zhengzhou Wei Fei is engaged in APP development, WeChat development, software development, website construction and system customization development, and invites cooperation.
