Many people have the impression that software development seems to be just the job of a developer, and as long as you provide them with ideas, they will be able to meet your software needs. However, in reality, the process of developing a piece of software is much more than just the responsibility of the developer, and sometimes they require only a fraction of the resources and time required for the overall project. So, what exactly is the basic process of developing a piece of software? Today, Director Zhang will lead you to learn more about it!
1.Analysis and determination of the purpose of project development
At this stage, the software developer needs to determine the project to be developed and discuss it with the demander to clarify the requirements of the software development goals and specific functions required by the demander, and whether it can be achieved.
2.Requirements analysis
This is the second stage of the software development process and the stage where you define the specific idea for the proper running of software development. After determining that software development is feasible, a detailed analysis of the functional requirements of the software that the customer needs to implement must be carried out. At the same time, changes that may occur in the development process should be considered, and a requirement change plan should be formulated to deal with the occurrence of special situations to ensure the smooth progress of the software development process.
3.UI page design
3.1 Outline Design:
Developers first need to carry out a high-level design of the software system, that is, system design. The outline design needs to include the basic processing flow, organizational structure, module division, function allocation, interface design, operation design, data structure design and error handling design of the system, etc., so as to provide the basis for the detailed design of the software.
3.2 Detailed Design:
On the basis of the outline design, the developer needs to carry out the detailed design of the software system. In the detailed design, the main algorithms, data structures, class hierarchies and invocation relationships involved in the implementation of specific modules are described, and the design considerations of each program (each module or subroutine) at each level of the software system need to be explained for coding and testing. The requirements of the software should be fully allocated to the software as a whole. The detailed design should be detailed enough to be able to be coded according to the detailed design report.
4.Programming
Each stage in the software development process is the foundation for the next phase of implementation. Programming is based on the software design, the requirements of each part of the software design through the computer program ** to achieve operation, programming system.
1. Standardized program writing rules to ensure the understandability and maintenance of software programs.
5.Software testing
After the app function is developed, the tester will systematically test the entire project. This session will mobilize all relevant personnel in the project team. Testing is no less important than planning the features in the early stage, and if the team does not have professionally and systematically trained testers, it is likely that the project will fall short of the original design intent and miss some logical pitfalls.
The testing process is carried out in 4 steps, namely unit testing, integration testing, validation testing, system testing and release testing. Test the written system and prepare it for delivery if there are no problems.
6.Software delivery
The software development process completes the software development through the above core links, and the next step is that after the software development meets the customer's needs, the developer will hand over the software system to the customer, and deliver the software installation program, database data dictionary, "user installation manual", "user guide", demand report, design report, test report and other products to the customer.
At the same time, guide customers to install software and installation skills, remind customers to pay attention to the detection and precautions of software operation status, environment, server and related middleware, know the actual operation methods and use processes of customer software, and realize the tasks specified in the contract.
7.Acceptance
After receiving the software development results delivered by the developer, and carrying out actual operation, test and operation, and achieving satisfactory results, the user accepts the developed software.
8.Maintenance
Custom-developed software usually needs to provide after-sales service, regularly maintain the software, or modify the application software program according to the new needs of users, so that it can continue to meet the actual needs of customers. The company has gathered tens of millions of service providers including design, development, planning, marketing and other categories, and has successfully served more than one million enterprises, institutions and individual employers. The types of services (tasks) provided by the platform cover more than 300 detailed items in seven categories: design, development, decoration, copywriting, marketing, business, and VR.
