1 Introduction

1.1 Project background

Many parents want their children to be good people, but in practice, their parenting methods often do not meet expectations. This may be because these parents educate their children largely according to their own parents' education methods, which leads to some not-so-good methods being inherited and passed down. For example, some parents may use corporal punishment to punish their children for wrong behavior, which is not acceptable in today's society because it may cause not only physical harm but also psychological trauma. In addition, some parents may force their children to choose a career or study direction according to their own expectations, which is not conducive to the child's self-development and independent thinking ability. In some social and cultural contexts, parents may place more emphasis on the utilitarian value of their children, while ignoring their children's emotional and mental health.

Parents can be influenced by the media and the perceptions and expectations of those around them, rather than truly understanding their children's needs and personalities. For the above problems, many parents may have found that there may be problems in their education methods, but limited by their own vision and knowledge reserves, they cannot find a more efficient way to communicate with their children in daily life

question:

1. Parents lack family education knowledge and experience, and do not know how to effectively communicate with and educate their children.

2. Sometimes parents may be aware of the problem, but it is easy to forget quality education in normal education, and return to the previous education method, which will have a bad impact on children

 

1.2 Development Status and Advantages of Family Education Platform

1.2.1 Development status at home and abroad

        Market size and growth: With the continuous improvement of society's education level, parents pay more and more attention to their children's education. With the continuous development of the family education market, the scale of this market is also expanding. According to relevant data, the global family education market has exceeded 100 billion US dollars, and the annual growth rate of this market is as high as 10%.

my country has a huge base of children aged 3-18, and the family education market has huge potential. According to the 2021 education statistics released by the Ministry of Education, there will be nearly 250 million students in kindergartens, primary schools and middle schools in my country in 2021, of which kindergartens are in There were 48.0521 million kindergarten children, 108 million primary school students, 50.1844 million junior high school students, 26.0503 million regular high school students, and 13.1181 million secondary vocational school students.

At present, there are more institutions dedicated to emotional intelligence and family education on the market, such as 6q Education Zhile Planet Little Elephant Academy, etc. These institutions are basically used for their own live online teaching platforms. However, these online platforms are exclusively used for teaching by a single institution, with incomplete services, high operation and maintenance costs, and poor publicity effects. Our platform can provide a variety of services, such as: one-on-one guidance by online professional family tutors, rich family education resources and teaching materials, and a dedicated parent community to share educational experience and educational resources. At the same time, you can find like-minded people through the community parents to make appointments for offline parent-child activities or courses.

2.4 Data Dictionary and Data Flow Diagram

2.4.1 Data Flow Diagram 

Data flow of user login interface

 

The data flow for user login includes the following steps:

        The user enters a username and password on the client side, and the client sends these login credentials to the server side. The server-side verifies the validity of user credentials, and generates and stores login credentials (such as session IDs or tokens) on the server-side. The server then sends the login credentials back to the client as a response. After the client receives the login credentials, it stores them locally. In subsequent requests, the client will carry login credentials in the request to prove the user's identity. When the server receives a request with login credentials, it verifies the validity of the credentials, and performs corresponding operations or returns corresponding data according to user permissions. The user can continue to operate until he chooses to log out. At this time, the client sends a logout request to the server, and the server deletes the login credentials and terminates the user session. The user is redirected to the login page or home page to complete the logout operation. This process ensures the secure verification of user identities and allows users to perform related operations in the system.

 

 

Family Education Resource Module Process

 

The process of using the Family Education Resource Module is as follows:

        The user opens the webpage system platform and logs in his account. On the main interface, users can find the entrance of the family education resource module, such as the navigation bar or menu. After users click to enter this module, they can see the classification, search box or recommended content of various family education resources. Users can select topics or types of interest in resource classification according to their own needs, or enter keywords through the search box to search for specific resources. According to the user's selection and search criteria, the system will display relevant family education resources, such as educational articles, videos, courses, etc. Users can click on the title or thumbnail of the resource to further view the detailed information of the resource, such as author, introduction, rating, etc. If the user is interested in a certain resource, he can choose to bookmark it or add it to his personal bookmark for later viewing or reference. Users can also communicate and share with other users, such as leaving messages or comments under resources, or initiating relevant discussions in forums. In addition, users can also submit their own family education resources, such as articles, courses or recommended bibliography, to the platform according to their needs and interests.

 

Family Education Instructor Appointment Consultation Process

 

The data flow for family education instructors to make an appointment for consultation is as follows:

        The user logs in to the web system platform and browses the family education instructor module. Users can browse through different tutor listings and view information such as each tutor's profile, area of ​​expertise, experience, and more. Users can choose a suitable tutor according to their needs and preferences. After selecting a tutor, the user can enter the tutor's detailed profile page, and check the tutor's available time slots and consultation fees and other information. Users can choose a suitable time period and make an appointment consultation. When making an appointment for a consultation, the user needs to provide relevant information, such as appointment date, time, consultation content, etc. Users can choose to pay the consultation fee online, or choose other payment methods. Once the appointment is successful, the system will send a confirmation message to the user and inform the tutor about the details of the appointment. The tutor will accept consultation at the appointment time and provide users with corresponding family education guidance and support. Users and tutors can consult and communicate through online chat, video conference or telephone. After the consultation, users can evaluate and comment on the tutor's services.

Parent Forum Module Process

The data flow of the parent forum is as follows:

        After the user logs in to the web system platform, he navigates to the parent forum module. In the parent forum, users can browse different topic sections, posts and comments. Users can choose to view popular posts, latest posts, or search for content of interest based on keywords. When the user chooses to view a specific post, the client sends a request to the server to obtain the detailed information, comment list and replies of the post. After receiving the request, the server gets the corresponding data from the database and sends the data back to the client as a response. The client will display the received data to the user, including post content, author information, comment list, etc. Users can like, bookmark, comment on posts or reply to other users' comments. When a user submits a comment or reply, the client encapsulates the content entered by the user into request data and sends it to the server. After receiving the request, the server stores the comment or reply in the database and generates a corresponding notification. If other users like, comment or reply to the post, the server will push the corresponding notification to the relevant users. The whole process aims to provide a platform for users to participate in parent forums, publish posts, comment and communicate, and realize interaction and knowledge sharing among users.

4.1.3 Brief description of development technology

1. Front-end development technology: Front-end development mainly involves user interface design and realization of interactive functions. Common front-end development technologies include HTML, CSS, and JavaScript. Use front-end frameworks and libraries such as React, Vue.js to simplify the development process and improve user experience.

2. Back-end development technology: Back-end development is responsible for processing business logic, data storage and processing, etc. The back-end development technology includes development using programming languages ​​such as Python, Java, and Node.js, and using corresponding frameworks such as SpringCloud to accelerate development and provide web services.

3. Database: In order to store data such as family education resources, user information, and forum posts, it is necessary to select an appropriate database system. We use the relational database MySQL

4. Server and hosting: The webpage system needs to be deployed and run on a server. Choose cloud service provider Tencent Cloud to provide servers and infrastructure for deployment.

5. Security and authentication: Since sensitive information such as user login and data privacy are involved, the system should consider security and authentication mechanisms. For example, use the HTTPS protocol for encrypted communication, use password hash and salt value encryption to store user passwords, use tokens (Token) for user authentication, etc.

6. Version control and team collaboration: Use a version control system (such as Git) to manage code versions and collaborative development, while using appropriate project management tools (such as Jira, Trello) to track tasks, issues, and progress.

7. Monitoring and logging: In order to ensure the stability and performance of the system, monitoring tools (such as New Relic, Datadog) can be used to monitor the operating status of the system, and logging tools (such as ELK Stack, Splunk) can be used to collect and analyze system log.

4.1.4 Detailed Explanation of Project Development Technology

1) MVC pattern

The MVC pattern ( Model - view - cont roller ) is a software architecture pattern in software engineering , which divides  the software system into three basic parts : model ( Model ), view ( View ) and controller ( Controller ).

        The purpose of the MVC  pattern is to achieve a dynamic program design , simplify subsequent modification , and  make it possible to reuse a certain part of the program . In addition , the MVC pattern makes the structure of the program more intuitive by simplifying the complexity . While the software system separates its basic parts , it also endows each basic part with its due functions . Professionals can be grouped according to their expertise :   

  1. Model: The model layer is responsible for handling data acquisition, storage and processing. In this project, data such as family education resource library, user information, and forum posts can be regarded as models. The model layer is responsible for data interaction with the backend and provides data to the controller layer.
  2. View (view): The view layer is responsible for displaying data to users and receiving user operations and input. In this project, the view layer includes the family education resource display page, the appointment consultation interface and the parent forum interface, etc. The view layer displays the data provided by the model layer, and passes the user's operations to the controller layer for processing.
  3. Controller (controller): The controller layer is responsible for processing user operations and input, as well as business logic processing. In this project, the controller layer receives the user's appointment consultation request, publishes forum posts and other operations, and processes and logically judges the data according to business rules. The controller layer interacts with the model layer, obtains or updates data, and passes the processing results to the view layer for display.

                                                          Figure  4-11 MVC pattern diagram

By adopting the MVC mode, different functional modules of the project can be separated to improve the maintainability and scalability of the code. The separation of model, view, and controller allows development teams to develop different parts in parallel and make modifications and adjustments to functionality easier. In addition, the MVC pattern also helps to achieve the separation of business logic and interface, improving code reusability and testability.

2) Nginx technology

The reverse proxy ( Reverse  Proxy ) method refers to the use of a proxy server to accept connection requests on the Internet , then forward the requests to the server on the internal network, and return the results obtained from the server to the client requesting the connection on the Internet . At this time, the proxy server acts as a reverse proxy server externally .   

The reverse proxy acts on the server side and is a virtual ip (VIP) . For a user request , it will  be forwarded to one of the multiple back-end processors to process the specific request .

The client is unaware of the existence of the proxy, and the reverse proxy is transparent to the outside world , and the visitor does not know that he  is visiting a proxy . Because the client can access without any configuration .

Reverse proxy,   "it represents the server", is mainly used in the case of distributed deployment of server clusters, and the reverse proxy hides the information of the server .

The role of reverse :

  1. Static resource service: Nginx can directly provide services for static resources (such as HTML, CSS, JavaScript, pictures, etc.), reducing the burden on the back-end server. By configuring Nginx, requests for static resources can be directly processed by Nginx, improving the loading speed and concurrent performance of web pages.
  2. Reverse proxy: Nginx can be used as a reverse proxy server to forward the client's request to the back-end server for processing. In this project, when a client initiates a request, Nginx can be responsible for forwarding the request to the appropriate backend server, such as processing requests for user login, obtaining family education resources, etc.
  3. Load balancing: If the project needs to deploy multiple back-end servers to handle a large number of requests, Nginx can be used for load balancing. Nginx can distribute requests to multiple back-end servers according to a preset algorithm to achieve balanced distribution of requests and improve system performance and reliability.
  4. Cache control: Nginx provides a cache function, which can cache dynamic pages or static resources, reduce requests to back-end servers, and improve response speed. By configuring the caching rules of Nginx, different pages or resources can be cached to improve system performance and user experience.
  5. SSL/TLS encryption: If the project involves the transmission of user privacy information (such as login, payment, etc.), Nginx can provide SSL/TLS encryption to protect data security. By configuring the SSL certificate and cipher suite of Nginx, the encryption and security protection of transmitted data can be realized.

 

                                                       Figure 2-2 Principle of reverse proxy

As a powerful and flexible web server and reverse proxy server, Nginx can provide high performance, reliability and security services, which is suitable for the deployment and management of this project.

3) Getway gateway service

Spring  Cloud  Gateway is a gateway developed by Spring based on technologies such as Spring  5.0 , Spring  Boot  2.0 and Project Reactor . It aims to provide a simple and effective unified API routing management method for microservice architecture . Its goal is to replace Netilx Zuul , which not only provides a unified routing method , but also provides basic functions of the gateway based on the Filter chain , such as : security , monitoring / indicators and current limiting .       

Gateway application:

  1. Unified entrance: use the Gateway gateway as the unified entrance of the system, and send all client requests to the Gateway gateway.
  2. Routing and load balancing: According to the requested URL path, request header and other information, the request is routed to the corresponding backend service. If there are multiple instances of backend services, the Gateway gateway can also perform load balancing and evenly distribute requests to these instances.
  3. Authentication and authorization: Integrate authentication and authorization services to authenticate and authorize requests. For example, you can verify a user's token or session in the Gateway and check if the user has permission to access a specific resource.
  4. Security: Provides security protection, such as preventing DDoS attacks, IP filtering, request flow limiting, etc. In addition, Gateway can also encrypt transmitted data through SSL/TLS to protect user privacy and sensitive information.
  5. Caching and performance optimization: implement caching of responses, reduce the load on backend services and improve response speed. By configuring the cache policy, the Gateway can cache static resources or response results to provide a faster access experience.
  6. Logging and Monitoring: Logs requests and responses to help with troubleshooting and system monitoring. You can use log analysis tools to analyze and monitor request traffic and detect system anomalies.

                                                        Figure 2-3 Getway Composition

Simplifies the architecture and deployment of the system, and improves the scalability, security and performance of the system. At the same time, the Gateway gateway also provides centralized request routing, authentication and authorization functions, which reduces the burden on back-end services and provides a better user experience.

4) Spring Cloud framework

        Spring  Cloud is an ordered collection of a series of frameworks. It uses the development convenience of Spring  Boot to subtly simplify the development of distributed system infrastructure , such as service discovery registration , configuration center , message bus , load balancing , circuit breaker , data monitoring, etc. , can all use the development style of Spring Boot One-click start and deployment . Spring does not repeat manufacturing wheels, it just combines the relatively mature and practical service frameworks developed by various companies at present , and repackages through Spring Boot style to shield the complex configuration and implementation principles. A set of distributed system development kits that are easy to understand, easy to deploy, and easy to maintain are reserved for developers .         

4.2 System Implementation

4.2.1 Registration and login page design

The background of a simple dynamic login interface can be a light and flowing animation effect, giving users a modern and lively feeling. Here is an example:

Background: Use pure white as the main color, with soft colors from top to bottom.

Dynamic Effects: Apply light animation effects to the background

  • The background subtly breathes: The background color gently fades in and out, giving it the appearance of breathing.
  • Flowing Particles: Generates small particles in the background that float, spin, or drift slowly.
  • Background Image Fade: Alternately displays a series of related images in the background, which can be faded in and out or switched in a gradient.
  • Smooth transitions: Backgrounds can fade in or out with smooth animated transitions as the page loads or switches states.

A dynamic background like this can add some liveliness to a login screen and grab the user's attention while keeping the page clean and focused. It can provide users with a pleasant login experience and matches the modern design style.

Login Page Design:

  • Page Title: Login
  • Form fields:
    • Password: Enter the password box, the user enters the password

  3. - Rotation function: Each card can realize the rotation function, that is, the content of the card can be switched by clicking or sliding according to the user's interaction. This can be achieved through animation effects or swipe gestures. When a card is clicked, the card enlarges or produces other visual effects to highlight the currently selected card.
  4. - Card content: Each card shows the name of the module, a brief description and an associated icon. Users can quickly understand the function of each module according to the information on the card. When a card is clicked, the page navigates to the corresponding module page.

         The overall design concept is clean, modern and intuitive. The black background provides high contrast throughout the page, making the content of the card stand out even more. The carousel function provides an interesting way of interaction, allowing users to quickly switch between different modules. Cards should be designed with care for consistency and ease of use, allowing users to easily understand and navigate to the required functional modules. Specific styles and animation effects can be further customized and adjusted according to project requirements and user experience.

5. Project summary and application prospect analysis

5.1 Project Summary 

5.1.1 Design Formation Process

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.

5.1.2 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.

Through this project, especially the design of these four sub-modules, we learned to use ER diagrams to clearly define and represent entities, attributes and relationships. By defining entities, attributes, and relationships, data structures and operations in a database can be more clearly represented. When modeling, properly naming entities and attributes, ensuring their semantics are accurate, and using appropriate data types and constraints can improve data validity and integrity. Selecting the appropriate data type, index and storage structure can optimize the performance and efficiency of the database; according to the demand and query frequency, set the appropriate index. Indexes can speed up query operations, but too many indexes will increase the complexity and storage overhead of data updates. Therefore, I weigh the pros and cons and select the most frequently queried fields as indexes to ensure the effectiveness of the indexes and the performance of the database.

In general, this experiment has greatly improved my database design ability. Through practical operations, I am familiar with the process and methods of database design, and have a deeper grasp of tools such as MYSQL. In future work and study, I will be able to design and implement databases more independently and effectively.

5.2 Application Prospect Analysis and Prospect

The family education platform system project has broad application prospects. The following are some relevant analyzes:

1. Growing demand for family education: As parents pay more attention to their children's education, the demand for family education resources and guidance is also increasing. The family education platform system can meet the needs of parents for educational resources, guidance and consultation, and provide convenient and efficient services, so it has broad market potential.

2. Support of technological development: With the continuous development of technology, such as the popularity of smart phones, high-speed networks and online learning platforms, the family education platform system can better integrate and apply these technologies to provide richer and more personalized educational resources and service.
