Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional software development methods are used, then applications can be developed with full functionality, but extensive programming expertise is required and development costs are high
Solution Approach 1:
The patent introduces a visual development environment and metadata-driven architecture as intermediaries between the user and the complex programming processes. Users interact with high-level visual tools and configuration interfaces rather than directly writing code, while the system automatically generates the underlying software code from metadata descriptions at runtime. This mediator layer abstracts away the complexity of programming languages, data structures, and algorithms from the end user.
Solution Approach 2:
The system uses templates and pre-defined software code patterns that can be copied and adapted through configuration rather than created from scratch. Metadata templates define common application structures, data models, and business logic patterns that users can instantiate and customize through visual interfaces, eliminating the need to manually program each component while maintaining full functionality.
2Productivity
If skilled programmers are hired to develop applications, then high-quality software can be produced, but labor costs increase significantly
Solution Approach 1:
The system enables end users to independently develop and deploy applications without requiring external programming expertise. The visual development environment provides self-service capabilities where users can define data structures, configure business logic, and generate functional applications through intuitive graphical interfaces and metadata configuration, eliminating the need to hire specialized developers for routine application development tasks.
Solution Approach 2:
The system performs preliminary actions by pre-compiling and caching software code from metadata descriptions before runtime. The metadata-driven architecture allows applications to be defined once in a high-level format, and the system automatically generates and optimizes the underlying code in advance, enabling rapid deployment and iteration without requiring skilled programmers for each modification.
3Adaptability or versatility
If custom software is developed from scratch, then specific business requirements can be met, but development time and costs increase
Solution Approach 1:
The system provides dynamic adaptability through a metadata-driven architecture where application behavior and data structures can be modified at runtime without recompilation. Users can dynamically configure data models, business rules, and integration parameters through visual interfaces, and the system automatically adapts the generated software code to meet changing business requirements, enabling rapid customization without traditional development cycles.
Data Source
AI summary
Data structures and applications are defined with the point-and-click visual tools or speech recognition and recorded as metadata descriptions, which are converted at runtime to generate underlying software code (e.g., C #, SQL, JavaScript, etc.) to implement the application. The data structures include application data elements described in a data serialization format, such as JSON, are stored in a NoSQL database. Each application data element includes fields that each represent an individual value. Each field is defined with a label, a data type, and attributes. The data structures also describe relationships or links between application data elements, as well as data-driven or time-based rules that drive further data manipulation and interactions within and external to the programming development environment through a variety of interfaces (e.g., HTTP, SMTP, SMS).
