Wherein, the function definition refers to analyzing service requirements, and the specific functions to be realized in the service system are explicitly and specifically described and specified, which can include defining event types, trigger conditions, event processors, parameter transfer, exception handling and the like.

The service personnel can perform function definition through the function designer, such as page style setting, file path configuration, data access configuration and the like.

The triggering event refers to that when a specific condition is met in the service system, corresponding operation or processing logic is automatically triggered.

For example, in a web page of a business system, when a user clicks a button or a mouse moves into an area, a corresponding event is triggered, thereby performing a specific operation or processing logic.

In actual implementation, the business personnel can configure the module event through an import and custom mode, and import the public event into the function designer to realize the business function of the module, such as adding, deleting, importing, exporting, auditing and the like.

By carrying out function development of the service system based on event driving, a large number of public events can be accumulated and deposited in the service system, and the modules can be quickly imported, customized and applied during development.

Wherein the common events are frequently used common events or event types in the service system, and the common events can be triggered and processed in different modules or components to realize decoupling and reuse of service codes.

The form information may be related attributes and definitions of user interface forms used in the business system, including form attributes and related configuration information, which may include form names, field definitions, and triggers, and related configuration information may include layout definitions and check rule definitions.

In actual execution, a page designer is called to define module attributes and save the module information into a tool_function table, define field attributes and save the field information into a tool_function_column table, define table attributes and save the table attributes into a tool_function_grid table, define table attributes and save the table attributes into a tool_function_form table, and the page designer reads relevant configuration information saved in the tool_function table, the tool_function_column table, the tool_function_grid table and the tool_function_form table, analyzes and generates HTML page codes, and saves the HTML page codes into a table file and a table file according to interface call.

In some embodiments, the platform further comprises a container orchestration system that is further used to manage applications developed by the cloud-developed low-code development platform 100.

Wherein the container orchestration system may be built based on a container-based cluster management platform (Kubernetes, K8 s).

In actual execution, container arrangement is applied to the low-code development platform 100 for cloud development by using K8s, and automation such as creation, import, export, release, and operation is realized.

For example, the container orchestration system first creates a Docker image, requiring that the application be packaged as a Docker image. The Docker image is a portable, self-contained application running environment, which contains the application and its dependencies.

Next, a configuration file of a container orchestration system is defined, in which deployment and management of an application is described using another configuration file in a markup language (Yet Another Markup Language, YAML) format, in which information such as the number of copies of the application, container images, and resource requirements are defined.

Furthermore, a container orchestration system object is created.

The container orchestration system uses kubectl commands or Kubernetes APIs to create objects defined in the configuration file into the container orchestration system.

The objects defined in the configuration file may include Deployment, service and Ingress et al, where Deployment is a Kubernetes object that defines the Deployment specification of an application.

The container orchestration system then proceeds with automated deployment.

The container orchestration system automatically creates and manages copies of the application in the cluster based on the number of copies defined in the discover configuration file, uses a scheduler to allocate groups of containers (Pod) to nodes in the cluster, and ensures that there are sufficient resources on each node to run the application.

The container orchestration system then monitors and expands.

The container orchestration system provides monitoring and automatic expansion functions, and can automatically increase or decrease the number of copies of an application program according to CPU utilization or other metrics by defining a horizontal expander.

The container orchestration system then performs service discovery and load balancing.

The container orchestration system provides Service discovery and load balancing functions through Service objects, where Service provides a stable web portal for applications and distributes requests to backend Pod.

The container orchestration system may then also update and roll back.

When the application program needs to be updated, the application program can be updated by modifying the mirror version or other parameters in the configuration file of the development, and the container arrangement system automatically performs rolling update according to the new configuration, so that the high availability of the application program is ensured.

Finally, the container orchestration system may also implement log and event management.

The container orchestration system provides various tools and plug-ins to collect, store, and manage logs and events for applications.

Wherein the Pod log can be viewed using kubectl command, or centralized log management using a third party tool.

In some embodiments, the backend application development architecture 120 further includes a version management server for full code development and a code development module for storing code in accordance with an engineering file structure of an engineering project.

Among them, a version management Server (SVN) is a version control system for managing changes to files and directories, allowing multiple persons to work on the same file, tracking changes to files, and being able to rollback to previous versions.

The SVN may use a client-server model, with developers interacting with the server through the SVN client.

The code development module is constructed based on an integrated development environment (Integrated Development Environment, IDE) and is responsible for the requirements of the business module and individuation, and can be developed in a full-code development mode, so that the full-code developed codes are integrated into a low-code engineering project, and the symbiosis of the low-code development and the full-code development is realized.

In actual execution, the method is integrated with a version management server to realize effective source code version management and control, engineering projects on the SVN can be imported into a code development module to carry out custom development and packaging operation, so that full code development is carried out on applications developed by low codes, code files automatically generated by application development can be correspondingly stored in the SVN according to engineering file structures, automatic release is realized by utilizing a hot deployment technology, and application hot deployment is updated and deployed immediately.

The cloud development low-code development platform 100 provided by the embodiment of the application focuses on data modeling driving and service configuration, provides a development environment combining low-code development and full-code development, and fully utilizes and plays the professional expertise of a good developer to connect with service personnel for collaborative development.

The low-code development platform 100 for high-cohesion and low-coupling cloud development can greatly improve development efficiency, reduce the pressure of code development of developers and activate the potential of service carding so as to quickly realize an available and easy-to-use service system.
