Stage division
1 plan
To provide a general definition of the problem to be solved, including understanding the user’s requirements and the actual environment, from technical, economic and social factors, etc. Study and demonstrate the feasibility of this software project in three aspects, prepare a feasibility study report, explore solutions to the problem, and assess the cost of available resources (such as computer hardware, system software, manpower, etc.), the benefits and benefits that can be obtained Estimate the development progress and formulate an implementation plan to complete the development task.
2Analysis
Software requirement analysis is a systematic analysis and assumption of what kind of software to develop. It is a process of removing the rough and precise, removing the false and keeping the truth, and correctly understanding the user's needs, and then expressing it in the software engineering development language (formal function specification, that is, the requirements specification). The basic task of this stage is to determine the problem to be solved together with the user, establish the logical model of the software, write the requirement specification document and finally get the user's approval. The main methods of demand analysis include structured analysis methods, data flow diagrams, and data dictionaries. The work of this stage is to design and establish the architecture of the corresponding software system according to the requirements of the requirements specification, and decompose the entire system into several subsystems or modules, define the interface relationship between the subsystems or modules, and design each subsystem in detail. Define, write software outline design and detailed design specification, database or data structure design specification, assembly test plan. In the initial stage of any software or system development, user needs must be fully grasped in order to prioritize which functions should be implemented, which specifications should be adopted, and which restrictions should be set in the following system development process. The system engineer will finally complete the design plan based on this, and on this basis, define the description and limitations of the subsequent program development, system functions and performance.
3Design
Software design can be divided into two stages: outline design and detailed design. In fact, the main task of software design is to decompose software into modules, which are program units that can realize a certain function of data, program descriptions, and executable programs. It can be a function, process, subroutine, a piece of independent program and data with program description, or a functional unit that can be combined, decomposed, and replaced. Module, and then design the module. The outline design is the structural design, and its main goal is to give the module structure of the software, which is represented by the software structure diagram. The primary task of detailed design is to design the program flow, algorithm and data structure of the module, and the secondary task is to design the database. The common method is still the structured programming method.
4 Coding
Software coding refers to the conversion of software design into a computer-acceptable program, that is, a "source program list" expressed in a certain programming language. A full understanding of software development languages, tool features, and programming styles will help you choose development tools and ensure the quality of software product development.
In the current software development, except for special occasions, the high-level languages of the 1980s are rarely used, and object-oriented development languages are used instead. Moreover, the object-oriented development language and development environment are mostly integrated, which greatly improves the speed of development.
5 tests
The purpose of software testing is to find as many errors as possible at a relatively small cost. The key to achieving this goal is to design a set of excellent test cases (test data and functions and expected output results constitute test cases). How to design a set of excellent test cases, the key lies in understanding the test method. Different test methods have different test case design methods. Two commonly used test methods are the white box method. The test object is the source program, which is based on the internal logic structure of the program to find software programming errors, structural errors and data errors. Structural errors include logic, data flow, initialization and other errors. The key to use case design is to cover as many internal program logic results as possible with fewer use cases. The white box method and the black box method are based on the software function or software behavior description, and the software interface, function and structure errors are found. The interface errors include internal/external interfaces, resource management, integration, and system errors. The key to the use case design of the black box method is also to cover the output and input interfaces of the module with fewer use cases.
6Maintenance
Maintenance refers to some software engineering performed on the software product after the software development (analysis, design, coding and testing) has been completed and delivered to use Activities. That is, according to the operating conditions of the software, the software is appropriately modified to adapt to the new requirements and to correct the errors found in the operation. Compile software problem reports and software modification reports.
For a medium-scale software, if the development phase takes one to two years, after it is put into use, its operation or working time may last for five to ten years. Then its maintenance phase is also during the five to ten years of operation. During this period of time, people almost need to solve the various problems encountered in the development stage, and at the same time also solve some of the unique problems of the maintenance work itself. Doing a good job of software maintenance can not only remove obstacles and make the software work normally, but also make it expand its functions, improve performance, and bring obvious economic benefits to users. Unfortunately, the emphasis on software maintenance is often far less than that on software development. In fact, compared with software development, the workload and cost of software maintenance are much larger.
In the actual development process, software development does not proceed from the first step to the last step, but at any stage, there is generally one or several steps back before entering the next stage. Problems in the testing process may require modification of the design, and the user may propose some needs to modify the requirements specification, etc.
Facilities requirements
1Development platform
The software development platform originates from the tedious practical development process. In practice, developers summarize and encapsulate commonly used functions, classes, abstractions, interfaces, etc., and become "middleware" that can be reused. As the "middleware" matures and generalizes, it becomes more powerful and capable The software development platform came into being to meet the needs of enterprise-level customers.
The platform is the gathering of scientific research results over a period of time, and it is also a sign of the staged platform period, which provides a foundation for the industry to enter a new field of research and development. As the platform has significantly improved the core competitiveness of enterprises, the application of software development platforms in the domestic management software market has become a trend.
Due to differences in development environment, developers, functional positioning, industry background, etc., platforms of different brands are quite different.
2Development Environment
Software development environment is also called Integrated Project Support Environment (IPSE) in Europe. The main component of the software development environment is software tools. The man-machine interface is a unified interactive dialogue system between the software development environment and the user, and it is an important quality mark of the software development environment. The software environment database that stores the software products or semi-finished products (such as source code, test data and various documents, etc.) produced by the processing of various software tools is the core of the software development environment. The connection and mutual understanding between tools are achieved through shared data stored in the information database.
The software development environment database is a knowledge-based information database for software workers, and its data objects are diversified and intelligent. The software development database is used to support the active or passive work of various software tools, especially automatic design tools and compilers.
The more elementary SDE database generally includes a general subroutine library, a reconfigurable program processing information library, a module description and interface information library, a software test and error correction basis information library, etc.; a more complete SDE database also Should include feasibility and demand information files, detailed files of stage design, test-driven database, software maintenance files, etc. A further requirement is to automate the whole process from software planning to realization and maintenance. This requires the SDE database system to be intelligent, among which the more basic intelligent result is the automatic realization and optimization of software coding, and many different aspects of software engineering projects. Self-analysis and summary of perspectives. This kind of intelligent result should also be actively remodeled and learned to enrich the knowledge, information and software accumulation of the SDE database. At this time, the software development environment is gradually moving towards a high degree of intelligence and automation with the appropriate external control or help of software engineers.
The basis of software implementation is computer language. Today, computer languages have developed into algorithm languages, database languages, intelligent simulation languages and other categories. Among dozens of important algorithm languages, C&C++ language has increasingly become a close partner of the majority of computer software workers. This is not only because It has powerful functions and flexible structure. It also provides a highly structured grammar, a simple and unified software construction method, which makes the design and construction of the subroutine library, the basic component of the SDE database based on it, seem unusual. Convenient.
3 development languages
Common software development languages: JAVA, C/C++/php/JSP/ASP/POWERBUILDER/DELPHI/.NET/C#/vb/ etc.
Databases are used for the most critical needs of the application. Common databases: MySQL/SQLSERVER/ORACLE, etc.

② As long as the parties to the contract agree on liquidated damages or compensation for losses, they must agree on a specific amount or calculation method. When the liquidated damages are agreed upon, the agreed amount cannot be too high or too low. If the agreed amount is too low, the loss will not be compensated, and the agreed amount will be too high and cannot be realized because the amount is too high without legal support. Generally speaking, the agreed amount of liquidated damages cannot exceed the amount of the contract. If one party's loss does exceed the contract, it can directly agree to compensate for the loss.
