Description

Technical Field

[0001] The present invention relates to the technical field of low-code development platform design, and specifically, to a low-code digital development base design method and system. Background Art

[0002] In recent years, the wave of digital transformation has swept across all walks of life, and more and more companies have begun to pay attention to the efficiency and flexibility of software development. In this context, the Low-Code Development Platform (LCDP) has quickly emerged with its features of ease of use, flexible configuration, efficient development, and low cost, and has gradually become the focus of enterprise digital transformation. The Low-Code Development Platform has opened up a new path for enterprise digital transformation and rapid software development and application.

[0003] Disadvantages of existing low-code development platforms:

[0004] Question 1: Low-code development platforms build application systems in a "minimal handwritten code" manner. Most of the code is automatically generated by the platform, and developers can only modify part of the code. The coding is highly customized, and the coding error rate is also controlled within a small range. Since developers can write part of the code and the platform has strong programmability, it also requires developers to have a deeper understanding of the basic logic of coding. Due to the high technical threshold for developers, it is difficult for non-professional developers to directly participate in application development, and true universal development cannot be achieved.

[0005] Question 2: Although low-code development platforms solve application system problems in the information and digital age, such as business process automation and data management, they cannot solve application system problems in the intelligent age, such as the Internet of Things, big data, AI and other technologies, resulting in developers being unable to use relevant technical capabilities of intelligence.

[0006] Question 3: After the low-code development platform system completes the application system development, the subsequent upgrade and deployment of the application is difficult, time-consuming, labor-intensive, and costly to operate and maintain. It is difficult for the owner to perform independent operation and maintenance, and the IT department can only rely on the original IT manufacturer, often encountering problems such as slow response to operation and maintenance needs and high costs.

[0007] Therefore, there is an urgent need to design a new low-code digital development base to solve at least one of the above problems. Summary of the invention

[0008] In order to solve the above problems, the present invention provides a low-code digital development base design method, including the following designs:

[0009] Backend code design: Based on the defined service parameter structure and service return value structure, service parameters are generated by arranging service content and setting the access service address to control the system engine to read and execute the service according to the service parameters, and then store the execution results in the service return value;

[0010] Front-end code design: Based on the defined script parameter structure and script return value structure, the script content is arranged, and the script is called on the product page to generate script parameters. After the system engine reads and executes the script according to the script parameters, the execution result is stored in the service return value, and the script return value is output to the script caller;

[0011] Model integration design: configure data for object models, big data models, and AI models, call nodes of each model in service orchestration, and perform related service operations based on node types;

[0012] Automated deployment design: Package and push the application version in the IDE. After modifying the application configuration data, send it to the designated server for system updates.

[0013] Preferably, in the process of backend code design, the service parameter structure is defined according to the data type of the service parameters, wherein the data type includes basic types consisting of strings, integers, floating-point numbers, dates, Booleans, and bytes, complex types consisting of objects and arrays, and nested combinations of basic types and complex types.

[0014] Preferably, in the process of orchestrating the service content, based on the functional nodes consisting of defined variables, assigned variables, conditions, loops, exception capture, service calls, database operations, object model operations, big data operations, AI model operations, string operations, date operations, object operations and array operations, the business logic services are orchestrated by free dragging and dropping, and the service definitions are persisted as XML format files, wherein the system engine executes the service by reading the XML format files of the services.

[0015] Preferably, in the process of front-end code design, the script parameter structure is defined according to the data type of the script parameter, wherein the data type includes basic types consisting of strings, integers, floating-point numbers, dates, Booleans, and bytes, complex types consisting of objects and arrays, and nested combinations of basic types and complex types.

[0016] Preferably, in the process of front-end code design, based on the functional nodes consisting of variable definition, variable assignment, conditions, loops, exception capture, back-end service calls, page opening operations, message notification operations, string operations, date operations, object operations and array operations, the business logic scripts are arranged by free dragging and dropping, and the script definition is persisted as an XML format file, wherein the system engine executes the script by reading the XML format file of the script.

[0017] Preferably, in the process of model integration design, for the object model, the information of object model attributes, labels, functions and events is defined, wherein the functions and events are implemented using service orchestration;

[0018] In the service orchestration, the object model node is called to call the object model related operations including: device communication, batch device communication, storage of device data, single data query, multiple data query, data paging query and device operation communication.

[0019] Preferably, in the process of model integration design, for the big data model configuration, the big data connection and model properties are defined, the big data node is called in the service orchestration, and data collection operations are performed to call big data related operations, including data extraction, column to row, row to column, and data merging.

[0020] Preferably, in the process of model integration design, the AI ​​model and its prompt word template are registered, and the AI ​​model node is called in the service orchestration to call the AI ​​model service node for AI model interaction.

[0021] Preferably, in the process of designing the automated deployment, a control center is set up to perform the automated deployment, wherein:

[0022] After designing the application functions in the IDE, package all the application resource data into a compressed package in a dedicated format, upload it to the control center to modify the application configuration data, and modify the response configuration according to the target environment for release;

[0023] Publish the application to the designated server through the control center. After selecting the application version and software version, select the server information to be published and notify the designated server to perform update deployment.

[0024] After receiving the notification from the control center, the server executes the system update program, wherein during the runtime, the server downloads the system update medium and automatically updates the system.

[0025] The present invention discloses a low-code digital development base design system, which is used to implement the above-mentioned low-code digital development base design method. The system includes:

[0026] The backend code design module is used to generate service parameters based on the defined service parameter structure and service return value structure by arranging the service content and setting the access service address, so as to control the system engine to read and execute the service according to the service parameters, and store the execution result in the service return value;

[0027] The front-end code design module is used to arrange the script content based on the defined script parameter structure and script return value structure, and call the script on the product page to generate script parameters to control the system engine to read and execute the script according to the script parameters, store the execution result in the service return value, and output the script return value to the script caller;

[0028] The model integration design module is used to configure data for object models, big data models, and AI models, call the nodes of each model in service orchestration, and perform related service operations based on the node type;

[0029] The automated deployment design module is used to package and push the application version in the IDE. After the application configuration data is modified, it is sent to the designated server for system updates.

[0030] The present invention discloses the following technical effects:

[0047] 1.5: System engine executes service: The system engine reads the service xml format file definition, inputs the service parameters, dynamically executes the service according to the service definition, and finally stores the execution result in the service return value

[0048] 1.6. System return result: output the service return value executed by the system engine to the service caller.

[0049] 2. Use business scripting to replace traditional front-end code writing, such as Figure 2 As shown:

[0066] 4.2: Modify application configuration data in the control center: The default configuration is the configuration data of the development environment. You need to modify the corresponding configuration according to the target environment for release. For example, if you deploy a test environment, you need to adjust the relevant data to the test environment data; if you deploy a formal environment, you need to adjust the relevant data to the formal environment data;

[0067] 4.3: Publish the application to the designated server in the control center: After selecting the application version and software version, select the server information to be published, and notify the designated server to perform update deployment;

[0068] 4.4: The runtime server obtains the release information from the control center: after receiving the notification from the control center, it executes the update system program;
