The invention discloses an application model generation method and device based on a low-code platform and a medium, and relates to the technical field of low-code application models. The method comprises the steps that user service data are collected, the service data are stored through forms, and the forms comprise a main form and sub-forms; the relation between the main form and the sub-form is identified, model elements are obtained, and the model elements comprise business entities, sub-entities, entity relations, value objects and aggregation roots; an external dictionary is introduced, model elements are expressed through
JSON, and a visual script model is generated; packaging the script model to obtain a deployment
package, and dynamically publishing the deployment
package to a
database; and when the
database exports the deployment
package, storing the deployment package as a
JSON file, and compressing and encrypting the
JSON file. According to the method, after the form is abstracted into the model, higher-degree reuse can be achieved, the
workload of repeated model design and application and form development is reduced, and the development process is faster.
