Detailed Description
Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form a part hereof, and together with the description serve to explain the principles of the invention, and are not intended to limit the scope of the invention.
It is to be understood that other technical terms, acronyms, etc. appearing hereinafter are prior art and those skilled in the art can understand the meaning based on context and are not described here too much for reasons of brevity.
In the description of the present application, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the invention. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.
Referring to fig. 1, in one embodiment of the present invention, a general rapid development method for a building digital information system is disclosed, comprising:
s101, establishing metadata of a target system according to a plurality of existing systems, wherein the metadata of the target system comprises at least one target entity, the target entity comprises an existing field, the existing field refers to the existing entities of the plurality of existing systems, the target system is a building digital information system to be developed, and the existing system is a building digital information system already developed;
s102, establishing a plurality of function nodes and documents corresponding to each function node, binding the documents corresponding to each function node with target entities required by the function node according to the function meaning of the function node to obtain a plurality of application components, and generating a page skeleton based on the plurality of application components;
and S103, acquiring page design information based on the page skeleton, and generating a system code according to the page design information and the metadata to obtain the target system.
Compared with the prior art, the metadata modeling is performed by referring to the existing entity in the existing system, so that the data is highly correlated, meanwhile, the data of different systems are integrated to rapidly develop, the existing data are taken, the difficulty degree of system development is greatly reduced, and meanwhile, the system has the characteristics of modularization and componentization by adopting the mode of functional nodes and documents, and the maintainability and the expandability of the system are improved.
It is understood that the present invention may be implemented by an existing low-code platform, and terms such as metadata, entities, functional nodes, etc. are words in the low-code platform, and those skilled in the art can understand the meaning of the terms.
Specifically, in a preferred embodiment, step S101, building metadata of a target system according to a plurality of existing systems specifically includes:
establishing a target entity of the target system according to the existing entities of a plurality of existing systems;
and generating front-end engineering codes and back-end engineering codes of the target system according to the target entity, and taking the target entity, the front-end engineering codes and the back-end engineering codes as metadata of the target system.
The above process establishes the target entity by referring to the existing entity, then generates the preliminary front-end engineering code (for displaying the page for the user to operate), the back-end engineering code (connecting the database and other frameworks as the background of the target system), and completes the realization of the preliminary framework of the target system. In this embodiment, the manner of referencing the existing entity can improve the reusability of the data, save repeated development steps, improve the development speed, and ensure the association between the data.
Metadata refers to data describing the structure, behavior, and characteristics of an application. It contains definition information for various objects, fields, relationships, rules, etc. of the application. Metadata provides the basis for developers and systems to automate the construction, deployment, and management of applications. By metadata, a developer can define data models, user interfaces, business rules, etc. for an application without having to write a large amount of code. The low code platform utilizes metadata to generate and execute specific implementations of the application. Using a metadata-driven low code platform, a developer can implement rapid application development through simple drag-and-drop, configuration, and setup operations. By the method, non-technicians can participate in the development of the application program, and development efficiency and flexibility are improved. Meanwhile, through an abstraction layer of metadata, the low-code platform can also support the expandability and maintainability of the application program. In this embodiment, the metadata includes a target entity, a front-end engineering code, and a back-end engineering code.
Specifically, the establishing a target entity of the target system according to the existing entities of the plurality of existing systems in the above process specifically includes:
acquiring existing entities of a plurality of existing systems as reference entities;
establishing an existing field and defining a reference relation between the existing field and a field which is the same as the existing field in a plurality of reference entities;
and establishing a unique field, and establishing a target entity of the target system according to the unique field and the existing field.
An Entity (Entity) refers to a data object or business Entity in an application. It represents a specific concept or an actual existence in the system such as a user, order, product, etc. Each entity has a set of attributes or fields to describe its features and attributes. A Field (Field) is a specific attribute in an entity that stores and represents information of the entity. The fields define various characteristics of the entity, such as name, type, length, constraints, etc. They may include different data types such as strings, numbers, dates, boolean values, etc. By defining entities and fields, in a low code platform, developers can create and manage database tables, data models, and relationships between entities. By configuring the attributes and behaviors of the fields, a developer can define functions such as data input, verification rules, interface display and the like. The embodiment improves the efficiency of establishing the entity and establishes the connection between different data by establishing the two fields of the existing field and the unique field for the reference entity.
The present invention also provides a more detailed embodiment for more clearly describing the above step S101:
by using a common cost management system in the building industry as a target system and communicating data of three existing systems, namely a purchasing and supply chain system, a construction management system and a document management system, the method can realize function multiplexing so as to achieve the aim of rapidly developing the informationized system.
The entities are first collected from the existing system as reference entities in the cost management system. The entity A1, the payment bill entity A2, the settlement bill entity A3, the construction management system designer information entity B, and the document management system design construction plan entity C1 and the contract management entity C2 in the purchasing and supply chain system design provider need to be cited.
The target entity D of the cost management system is designed, and its fields are divided into unique fields and existing fields. Existing fields may be completed by introducing fields in the reference entities A1, A2, A3, B, C1, C2 before introduction. Cost-related fields such as estimated cost, days, etc. are added as unique fields of the cost management system, only those fields need to be created by the developer alone.
After the target entity is designed, corresponding front and back end engineering codes are automatically generated through the entity, the entity is analyzed through a self-research analyzer of the low code platform, an intermediate language describing the relation between the entities is generated, the code generator generates the corresponding front and back end codes according to the intermediate language, and the sql codes contained in the engineering can automatically generate a database table corresponding to the entity designed before. All metadata related to the service can be successfully constructed through the steps, and the metadata is convenient for a developer to maintain and develop by taking the entity model as a carrier.
Compared with the traditional metadata modeling, the method multiplexes the entities in the existing system in a reference way, thereby greatly reducing the workload of metadata modeling. In addition, front-end and back-end engineering codes are automatically generated through the self-grinding analyzer and the code generator, so that the environment construction of developers and the writing of template codes are omitted. And the metadata modeling is completed, and meanwhile, the whole construction of the back-end service of the cost management system is completed.
Further, in a preferred embodiment, step S102 specifically includes:
creating a user interface module, and creating a plurality of functional nodes and corresponding documents in the user interface module;
binding a bill corresponding to each functional node with a target entity required by the functional node according to the functional meaning of the functional node to obtain a plurality of application components;
a page function node is created in the user interface module, the page function node for generating the page skeleton based on a plurality of application components.
In this embodiment, the module is an independent functional unit of the application program, and is used to implement a specific service requirement, and typically includes a set of related pages, components, logic, and data. Modules are one of the main ways to organize application structures in a low code platform. In this embodiment, only one user interface module for displaying the page is built, and the module includes a plurality of functional nodes, so that the system architecture is greatly simplified, and the simplicity of building the target system is improved.
Functional nodes refer to specific functions or operations in an application program, such as adding, deleting, modifying, looking up, importing, exporting, and the like. In low code platforms, functional nodes are typically associated with documents and entities for implementing various operations in the business process. Documents refer to documents or forms in business systems. In low code platforms, documents are typically used to describe business objects, business data, and business processes, including metadata and data fields that describe the data interactions and state changes of the various steps in the business process.
A module typically contains a plurality of documents and a plurality of functional nodes for implementing specific business functions. The module provides an organization structure which can organize the bill and the functional node together to form a complete business process. The bill is a core data object in the business process, and the functional nodes are various operations and processes on the bill, which are closely related and mutually influenced. In the embodiment, by defining the bill and configuring the function node, a developer can rapidly develop an application program which meets the service requirement and is easy to maintain.
The page skeleton is a template or foundation in the low code platform for laying out and organizing page structures. It defines the overall structure and layout of the page, including navigation bars, sidebars, content areas, etc., providing a unified page layout style and specification. In the embodiment, the page skeleton for organizing the pages is also realized through the functional nodes, so that the complexity of the system architecture is further reduced, and the development efficiency is improved.
The present invention also provides a more detailed embodiment for more clearly describing the above step S102:
in the development application component design phase, module management is used to create a user interface module as a user interface for a cost management system (i.e., a target system).
A document is then created and bound to entity D. After the operations are completed, the bill is automatically stored in a development platform management library, so that the operation of the business entity can be traced later, and development management can be conveniently carried out. In this way, it is ensured that all operations are recorded and can be traced back to the source. This not only helps the user to better understand the operation of the system, but also helps the user to find the root of the problem when it occurs.
A functional node is then created and the document is bound. This functional node is a critical part of the system and its role is to associate this specific document with a specific function. In this way, it is ensured that when a user performs an operation related to this document, the system will automatically invoke the function associated with this function node. By creating multiple functional nodes and corresponding documents in the module, the application component design of the entire system can be completed.
The user interface is mainly a browser page, so the method also uses a page function node as a page skeleton and binds the function node to a bill which is created before. Then the skeleton creator of the method can automatically generate the page skeleton meeting the current service requirement according to the data structure of the entity D bound by the bill.
Further, in a preferred embodiment, the step S102 further includes:
establishing a custom file, setting a preset field value of a preset field in the custom file, and associating the preset field value to a field which is the same as the preset field in metadata.
The above-mentioned custom archive may limit the values in the preset fields, for example, in a preferred embodiment, in order to improve the user experience, reduce the selection cost of the user, and reduce the range of the user input content by separately managing specific data. Such as gender (a preset field), a user can set a male value and a female value (preset field values) through a custom file and then associate the gender field in the metadata, so that the user can finally enter information only through selection instead of text input.
After the application component is designed, based on general addition, deletion and modification, a back-end java code with good expandability is written according to industry standards, wherein parts of the code, which represent bill types, modules, functions, custom files and references, are changed along with different application component designs so as to adapt to various business scenes.
Further, in a preferred embodiment, step S103, obtaining page design information based on the page skeleton, and generating a system code according to the page design information and the metadata, to obtain the target system, specifically includes:
acquiring the page design information based on the page framework, wherein the page design information is obtained through secondary development according to an application component in the page framework;
generating a page template code according to the page design information;
combining the page template code and the front-end engineering code to obtain a system front-end code;
and generating the system code according to the system front-end code and the back-end engineering code, and obtaining the target system.
Through the page firmware, the target system is built, and the target system has basic functions, but in the embodiment, secondary development is performed on the basis of the page framework so as to meet more special requirements of users, and the further requirements are realized through page design information. According to the invention, a page template code is generated according to page design information, and then the page template code and a front-end engineering code are combined to obtain a final system front-end code for the front end.
Specifically, in a preferred embodiment, the page design information includes field retention information, display information, and calculation information.
The present invention also provides a more detailed embodiment for more clearly describing the above step S103:
in this embodiment, a user page can be created through the page skeleton, and the page basically has the functions of information input, viewing, modification and the like, so that the basic service requirement is met. Aiming at the limitation of the existing low-code platform on the support of subsequent expansion development, the embodiment provides page design, and visual operation is provided for subsequent expansion development through page design information, so that the workload of development is reduced.
The page design information in this embodiment is based on the development component of the previous design, and the newly created page already has a relatively perfect function. The purpose of page design is mainly to facilitate the developer to expand secondary development through visual operation.
For example, in this embodiment, two pages need to be created again on the basis of the previous page skeleton, page a is used for previewing the cost list of each project, and page B is used for viewing the cost detail page of a specific project and maintaining the cost detail information of the project. Since pages a and B both depend on business entity D, some fields need to be deleted. The page design information of the two pages includes:
first, for page a, it copies entity D, only retains (i.e., field retention information and display information) the project name, works for a period, predicts several fields of cost, and deletes other fields in the copy.
Secondly, copying the entity D for the page B; the unique fields are reserved completely, and entities A2 and A3 in the purchasing and supply management system are reserved; reserving an entity B of the construction management system; the entities C1, C2 in the document management system are reserved.
Thirdly, calculating the construction period through two entities, namely a contractor entity C1 and a construction planning entity C2, then calculating the wages of workers through a personnel information entity B, and acquiring the material purchase cost (namely calculation information) through a payment bill entity A2 and a settlement bill entity A3.
After the page design information is designed, the page design information can be managed by a middle server, and the middle server can generate page template codes for each page. And (5) putting the page template codes corresponding to the two pages into the front-end engineering codes before obtaining the final system front-end codes. The method can ensure that the codes generated by page design are not exposed to developers, the generated codes are concise, and the maintenance cost is reduced.
And finally, generating the system code according to the system front-end code and the back-end engineering code, and obtaining the target system, thereby completing the construction of the target system. The above procedure can easily build a cost management system commonly used in the construction industry. User interface design is performed through data driving, so that the aim of quickly constructing and building a system is fulfilled.
