Description

Engineering platform grammar expression and interpretation method Technical Field The invention relates to the field of digital platform engineering, in particular to an engineering platform grammar expression and interpretation method. Background The digital platform engineering is a systematic concept integrating digital technology and a platform architecture, and is characterized in that a standardized and modularized technical platform is constructed to provide a bottom layer support and an efficient solution for enterprise digital transformation. The digital platform engineering is to integrate digital technologies such as cloud computing, big data, artificial intelligence, the Internet of things and the like by taking a platform as a carrier, so as to create a reusable and expandable technical base. The essence of the method is that complex technical capability is abstracted into modularized service through standardized architecture design, so that a business department can quickly call in a 'taking and using' mode, and development, deployment and iteration of digital application are accelerated. With the deep advancement of enterprise digital transformation, an application system development platform (Application System Platform, abbreviated as ASP) has become an important infrastructure for supporting informatization construction in the fields of scientific research, production, operation management and the like. The ASP platform integrates basic components such as a data model, a workflow, APP registration, buttons, rights, personnel, organizations, roles, data dictionaries and the like, supports the rapid construction of an application system framework through visual configuration, and realizes the customized development of service processing logic by combining program codes. However, with the continuous expansion of application scenes and the continuous improvement of complexity, the conventional ASP platform gradually exposes a series of problems and bottlenecks in the aspects of unified modeling, collaboration efficiency, intelligent capability and the like. The application system development scripting language oriented to platform engineering is not only a scripting language, but also an engineering expression tool, and aims to realize transition from 'low code + programming' to 'model driving development', and push a platform from 'configuration' to 'linguistic', so that the construction efficiency, collaborative capability and intelligent level of an application system are comprehensively improved. The current ASP platform is widely applied to a plurality of business fields such as scientific research, production, operation, management and the like, and has the core value of reducing the development threshold and improving the delivery efficiency by means of modularization and visualization. However, in the practical application process, the platform faces a plurality of deep problems such as lack of unified modeling standards, serious repeated construction of components, difficult system evolution, complex authority and flow configuration, high cross-team cooperation cost, weak intelligent capability and the like. Especially in the process of intelligent transformation of a propulsion platform, how to effectively introduce new technologies such as prompt word engineering, AI auxiliary modeling, intelligent generation and the like becomes a key difficulty of platform upgrading. These problems not only affect the ease and extensibility of the platform, but also limit its in-depth application in a wider business scenario. (1) Problems occur in the platform application mode of visual configuration and program development Currently, the ASP platform commonly adopts a hybrid development mode of visual configuration and program development. Although this mode reduces the partial development threshold, in practice the following problems remain: ① In terms of semantics, a unified semantic system is lacking between visual configuration and program codes, so that configuration logic and code logic are difficult to be consistent, semantics are split, ② is in terms of maintenance, configuration items are scattered and are difficult to be versioned, change histories are difficult to trace, maintenance is difficult, ③ is in terms of cooperation, different roles (business personnel and developers) use different tools and languages, and communication cost is high. A collaboration disorder; ④ is in the aspect of automation degree, a large amount of logics need to be manually encoded, automation generation and deployment are difficult to achieve, automation degree is low, ⑤ is in the aspect of reusability, configuration is difficult to reuse, repeated labor frequently occurs, and reusability is low. Therefore, a unified language system is needed to bridge the gap between the visualization and the code, and realize the integrated expression and management of the logic inside the platform.
