Educational system and functional design

Huixiang education system and functional design

Require:

1.      On the basis of demand analysis, determine the detailed functions of the project;

2.      Determine and describe the sub-functions and detailed content of each functional module;

3.      Complete transaction design and application design.

Steps:

1. System structure design and subsystem division

Divide the functional modules or subsystems of the system, and use the hierarchical diagram to describe the overall structure of the system, functional decomposition, and the mutual calling relationship and information interaction between each module.

The following is a simple hierarchical diagram example, showing the overall structure of the project and the mutual calling relationship and information interaction between various functional modules :

 

In the above hierarchical diagram, we divide the system into four main modules: family education resource module, family education instructor module, family education consultation module and parent forum module. Below each module are listed the functional submodules associated with that module.

There is a mutual call relationship and information interaction between different modules :

1. The family education resource module can provide a resource search function, which is used by the family education instructor module and the family education consultation module.
2. The family education instructor module and the family education consultation module need to call the function of the family education resource module to obtain relevant educational resources.
3. The parent forum module can interact with other modules, such as citing resource links in the family education resource module in forum posts, or providing forum post search functions in consulting services.

2. Detailed design of system function modules

According to the structured design method, on the basis of decomposing the system functions layer by layer, design and describe each functional module (if there is transaction processing) or subsystem of the system (in the form of IPO diagram).

4. User interface design

Determine the content, interface style, calling method, etc. of all human-machine interfaces, including form design, report design, etc., and describe them in graphic form.

1. Interface content design:
   • Interfaces should have a clear layout and structure that users can easily understand and navigate.
   • Use clear and concise language and terminology, and avoid overly technical or obscure vocabulary.
   • The interface should be consistent, maintaining the unity of interface elements with similar functions in appearance and interaction.
   • Provide clear guidance and feedback, such as labels, prompt messages, error prompts, etc., to help users complete operations and understand results.
2. Form design:
   • Form fields should be well laid out and grouped according to the type and length of input, making it easy for users to read and fill in.
   • Use clear labels and field descriptions to make it clear to users what each field means.
   • Consider using features like default values, autofill, and drop-down selections to reduce user input effort and errors.

   • Consider user habits and expectations, and design intuitive and easy-to-use interface elements, such as buttons, menus, navigation, etc.
   • Provide appropriate calling methods, such as triggering specific functions and operations through buttons, links, shortcut keys, etc.

experimental report:

Organize the experimental procedure documents to form an experimental report, and summarize the process of forming the functional design and the experimental experience.

Functional design is a crucial part of the software development process. It involves the refinement and specification of system functions, and provides clear goals and guidance for the development team. Collaboration and communication were crucial factors in the formation of the functional design. The following is my summary of the process of forming the functional design and the experience of cooperation.

The process of functional design formation:

The first is requirements collection and analysis. Before functional design, our team needs to fully communicate with customers or stakeholders to understand their needs and expectations. We conduct it through meetings, interviews, questionnaires, etc. Then, requirements analysts organize and analyze the collected requirements to determine the functions that the system needs to implement.

After the requirements analysis is completed, it is functional refinement and division. According to the requirements, the functions are further refined and divided, and the large functional modules of the system are split into smaller sub-functional modules. I think this helps the team better understand the relationships and dependencies between features and makes the development process more manageable.

A more important detail is the writing of functional specifications. This must ensure that people who have not learned databases, that is, customers can understand, then functional design reviews and discussions among team members are crucial. Reviews ensure that the functional design meets customer needs, aligns with the overall goals of the system, and is coordinated with other modules and components. In the functional design stage, it is necessary to write a functional specification, which includes a detailed description of each functional module, definition of input and output, business process, etc. This helps the development team gain a comprehensive understanding of functional requirements and implementation details.

The last is prototyping and iteration. In the process of functional design, prototyping can help us understand the appearance and interaction details of the function more intuitively. Through prototypes, we can discover potential problems or improvement points, and perform corresponding iterations and optimizations. After the functional design is completed, conduct final acceptance and confirmation with customers or stakeholders. This helps ensure that the functional design meets their expectations and provides the opportunity for final touches and adjustments.

Cooperation experience:

Good communication among team members and with the client is the key to successful functional design. The development team should actively listen to customer needs and feedback, and communicate with customers continuously to ensure that the functional design meets their expectations. Functional design requires a common understanding among all team members, and regular meetings, discussions, and training help foster a common understanding among teams and ensure that teams are aligned in the functional design process.

Summarized the following points of experience for the entire project

1. Iteration and Feedback: Feature design is an iterative process. Members must be encouraged to provide timely feedback and comments to improve and optimize the design. Timely feedback and iterations help improve the quality and effectiveness of functional design.
2. Flexibility and Adaptability: During the functional design process, the team needs to be flexible and adaptable to respond to changes in requirements and new challenges. As the project progresses, new requirements or adjustments may arise, and the team should be able to flexibly adjust the functional design and communicate with relevant personnel in a timely manner.
3. Documentation and document management: In the functional design phase, relevant documents need to be written, including functional specifications, design documents, etc. The team should ensure the accuracy, completeness and timeliness of the documents, and establish a suitable document management mechanism so that team members can easily review and update the documents.
4. Teamwork tools and techniques: Using appropriate teamwork tools and techniques can help facilitate teamwork and communication. For example, version control tools can help team members share and manage functional design documents, and collaborative editing tools can facilitate real-time collaboration and discussion among team members.
5. Risk Management and Problem Solving: Various risks and problems may be encountered during the functional design process. The team should be capable of risk management, identify and assess potential risks in a timely manner, and take appropriate measures to mitigate them. At the same time, the team should have the ability to solve problems, actively seek solutions, and cooperate with relevant personnel to solve problems.

Through good cooperation and communication, team members can jointly promote the formation of functional design and ensure that the design meets customer needs. Flexibility, feedback loops, and problem-solving skills are key factors in a team's successful feature design. At the same time, the rational use of tools and technologies, as well as the establishment of a good document management and risk management mechanism will also help to improve the quality and efficiency of functional design.
