[0013] Furthermore, constructing the correspondence between the main entity and the child entity includes:

[0014] On the canvas of the metadata visualization operation page, the main entity and the sub-entity are connected by arrows to construct the correspondence between the main entity and the sub-entity.

[0015] Furthermore, the system attributes include at least one of the following: document number, document type, and document status.

[0016] Furthermore, the business attributes include at least one of the following: the name information, number information, precision information, primary key information, and field information of the main entity.

[0017] Furthermore, the step of creating a digital model of the construction project based on the main entity, the sub-entities, and the correspondence between the main entity and the sub-entities includes:

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0036] In the description of the embodiments of this application, unless otherwise stated, "a plurality of" means two or more.

[0037] In this embodiment of the invention, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, apparatus, product or device that includes a series of steps or modules is not necessarily limited to those steps or modules that are explicitly listed, but may include other steps or modules that are not explicitly listed or that are inherent to such process, method, product or device.

The execution order of the named or numbered process steps can be changed according to the technical purpose to be achieved, as long as the same or similar technical effect can be achieved.

[0039] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0040] This invention provides a digital modeling method, apparatus, electronic device, and storage medium for building engineering, which will be described below.

[0041] like Figure 1 As shown, the present invention provides a digital modeling method for architectural engineering, comprising:

[0042] Step 110: Display the project creation page, obtain the business requirements of the construction project based on the project creation page, and create a digital system file for the construction project based on the business requirements;

[0043] Step 120: Display the metadata visualization operation page, obtain the main entity to be created based on the metadata visualization operation page, generate the system attributes of the main entity to be created based on the building engineering digital system file, and obtain the business attributes of the main entity to be created based on the metadata visualization operation page.

[0044] Step 130: Create the main entity based on the system attributes and business attributes of the main entity to be created;

[0045] Step 140: Obtain the business attributes of the sub-entity to be created based on the metadata visualization operation page, create the sub-entity based on the business attributes of the sub-entity to be created, and construct the correspondence between the main entity and the sub-entity;

[0046] Step 150: Based on the main entity, the sub-entities, and the correspondence between the main entity and the sub-entities, create a digital model of the building project.

[0047] Furthermore, the system attributes are built-in parameters corresponding to construction industry data, and the business attributes are user-inputted custom data; the system attributes include at least one of document number, document type, and document status; the business attributes include at least one of the main entity's name information, number information, precision information, primary key information, and field information; the business attributes of the main entity to be created are character data with a length not exceeding 32 characters.

[0048] Furthermore, the business attributes of the main entity to be created are data in the form of SQL (Structured Query Language) files.

[0049] Understandably, this refers to data in the form of SQL files, which allows for CRUD operations on the SQL database.

[0050] The method provided by this invention is used in the development scenario of digital systems for building engineering. It provides a method for generating system data structures and relational grid diagrams and basic data CRUD functions based on user visual operation and configuration. The method generates an intermediate language describing the data structure and relationships through user visual operation and configuration, parses the corresponding system data structure and grid relation diagram through a dedicated parser, and then generates basic CRUD logic to achieve the goal of rapid system development.

[0051] In some embodiments, constructing the correspondence between the main entity and the child entity includes:

[0052] On the canvas of the metadata visualization operation page, the main entity and the sub-entity are connected by arrows to construct the correspondence between the main entity and the sub-entity.

[0053] It is understandable that the metadata visualization operation page can be displayed on a monitor, and users can operate on the monitor. For example, on the canvas of the metadata visualization operation page displayed on the monitor, users can drag the arrow with their finger to make the main entity point to the child entity, thereby establishing an association, i.e., a correspondence, between the main entity and the child entity.

[0054] It should be noted that a main entity can establish a correspondence with one or more child entities.

[0055] In some embodiments, creating a digital model of a building project based on the main entity, the sub-entities, and the correspondence between the main entity and the sub-entities includes:

[0056] Upon receiving a download digital model instruction on the metadata visualization operation page, a digital model of the building project is created based on the main entity, the sub-entities, and the correspondence between the main entity and the sub-entities. The corresponding SQL file for creating tables and the CRUD function interfaces are then generated.

[0057] Understandably, after saving the data, the user returns to the metadata list page, clicks "Download Code," and enters the command to download the digital model. The system will then perform data modeling based on the user-defined metadata, generating the corresponding SQL file for creating tables and the CRUD (Create, Read, Update, Delete) functionality interfaces for the business backend.

[0058] In other embodiments, such as Figure 2 As shown, digital modeling methods for architectural engineering include:

[0059] Step 210: Users can create projects based on project or business needs. A project includes five attributes: project name, display name, database name, package name, and access root path. All attributes except the package name are required; the package name is automatically generated by the system.

[0060] Step 220: After creating a new project, the user creates metadata according to the page prompts. Metadata refers to the data that the user needs to model.

[0061] Step 230: After the user selects to add metadata, they will enter the metadata visualization interface. First, drag the main entity from the tree on the left into the canvas as the main table for this function. Clicking on the main entity in the canvas reveals two tabs: Business Attributes and System Attributes. System attributes are built-in parameters specific to the characteristics of construction industry data, including document number, document type, document status, etc. The system automatically generates these attributes by reading user information and the information entered by the user in previous steps, reducing repetitive steps in development. Business attributes are the data content that the user needs to enter. To correspond with the SQL database, as shown in the figure, business attributes include attribute name, display name, column name, data type, reference number, file number, data length, precision, whether it is a primary key, and whether nullable fields are allowed. There are 10 data types: character, integer, long integer, floating-point, boolean, date, timestamp, long text, image, and attachment. Choose according to the actual business. The user can enter data according to the page prompts, where a primary key must be specified, the data type must be character, and the data length must be no less than 32 characters. In addition, to provide users with a better experience, users can choose to upload an SQL file for data import, and the main entity will be automatically generated based on the SQL file.

[0062] Step 240: After the user completes the creation of the main entity, drag the child entities from the tree on the left into the canvas and add business attributes to the child entities in the same way as the main entity.

[0063] Step 250: After creating the child entity, drag an arrow from the main entity on the canvas to connect to the corresponding child entity. The arrow will automatically snap to the child entity, thus realizing a one-to-many relationship between the main entity and the child entities.

[0064] Step 260: After the user saves the data, they return to the metadata list page and click to download the code. The system will then perform data modeling based on the user-defined metadata, generating the corresponding table creation SQL file and the CRUD (Create, Read, Update, Delete) function interfaces for the business backend.

[0065] The present invention provides a digital modeling method for building engineering, comprising: displaying a project creation page; obtaining business requirements for the building engineering based on the project creation page; and creating a digital system file for the building engineering based on the business requirements; displaying a metadata visualization operation page; obtaining a main entity to be created based on the metadata visualization operation page; generating system attributes of the main entity to be created based on the digital system file for the building engineering; and obtaining business attributes of the main entity to be created based on the metadata visualization operation page; wherein the system attributes are built-in parameters corresponding to building industry data, and the business attributes are user-input custom data; creating a main entity based on the system attributes and business attributes of the main entity to be created; obtaining business attributes of sub-entities to be created based on the metadata visualization operation page; creating sub-entities based on the business attributes of the sub-entities to be created; and constructing a correspondence between the main entity and the sub-entities; and creating a digital model of the building engineering based on the main entity, the sub-entities, and the correspondence between the main entity and the sub-entities.

[0066] In the digital modeling method for building engineering provided by this invention, the business requirements of the building engineering are obtained by displaying the engineering creation page. Based on the business requirements, a digital system file for the building engineering is created. The system attributes and business attributes of the main entity to be created are obtained based on the metadata visualization operation page. The main entity is created, and the business attributes of the sub-entities to be created are obtained based on the metadata visualization operation page. The sub-entities are created based on the business attributes of the sub-entities to be created, and the correspondence between the main entity and the sub-entities is constructed. In this way, a digital model of the building engineering is constructed. All of the above processes are carried out quickly through interface operation for data initialization, data entry and database table establishment. Users do not need to write a lot of SQL statements for data modeling, which reduces the professional requirements of users. Digital models can be created by simply entering data through the visualization interface, which also reduces the workload of digital modeling of building engineering.

[0067] Furthermore, the method provided by this invention can also generate backend CRUD (Create, Read, Update, Delete) interfaces, greatly reducing the workload of data modeling. Based on relevant theoretical knowledge in the construction industry, some data parameters are provided with Chinese semantic descriptions and encapsulated, and input data is limited on the front-end interface, greatly reducing the difficulty of data modeling for computer industry developers and improving development efficiency.

[0068] like Figure 3 As shown, the present invention also provides a digital modeling device 300 for architectural engineering, comprising:

[0069] The first creation module 310 is used to display the project creation page, obtain the business requirements of the construction project based on the project creation page, and create a digital system file for the construction project based on the business requirements.

[0070] The acquisition module 320 is used to display a metadata visualization operation page, acquire the main entity to be created based on the metadata visualization operation page, generate the system attributes of the main entity to be created based on the building engineering digitization system file, and acquire the business attributes of the main entity to be created based on the metadata visualization operation page; the system attributes are built-in parameters corresponding to the building industry data, and the business attributes are user-inputted custom data;

[0071] The second creation module 330 is used to create a main entity based on the system attributes and business attributes of the main entity to be created;

[0072] The third creation module 340 is used to obtain the business attributes of the sub-entities to be created based on the metadata visualization operation page, create the sub-entities based on the business attributes of the sub-entities to be created, and construct the correspondence between the main entity and the sub-entities.

[0073] The fourth creation module 350 is used to create a digital model of the building project based on the main entity, the sub-entities, and the correspondence between the main entity and the sub-entities.
