Model Component Files for Zero-Downtime System Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems with compiled code and API-driven approaches have lengthy development cycles and complex deployment considerations, with modified systems being prone to breakage due to interdependent artifacts, leading to inefficiencies in system functionality updates.
Innovation Solution
The system represents information using model components, such as XML documents, that cross-reference each other to provide a comprehensive 'world view', allowing for efficient data management and service requests by combining user and model data through templates, enabling flexible and resilient system updates without requiring complete system restarts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional compiled code and API-driven approaches are used, then system functionality can be implemented, but development cycles become lengthy and deployment becomes complex
Solution Approach 1:
The system segments functionality into independent model components (XML documents) that can be individually created, modified, and deployed without affecting other components. Each model component represents a discrete system element that can be updated independently, eliminating the need for complete system recompilation and redeployment.
Solution Approach 2:
The system uses dynamic model components that can be modified at runtime without system restart. The model component files can be updated hot-swapped while the system continues to operate, allowing continuous deployment and eliminating fixed development cycles.
2Adaptability or versatility
If API-driven approaches with interdependent artifacts are used, then system functionality can be achieved, but the system becomes prone to breakage when changes occur
Solution Approach 1:
The system divides functionality into independent model components with explicit cross-references rather than implicit dependencies. Each component is self-contained and can be modified without affecting others, eliminating the chain reaction of breakages that occur in tightly coupled API-driven systems.
Solution Approach 2:
The system introduces model component files as intermediaries between system elements. These XML documents serve as a stable, versioned representation of system state that decouples components from direct API dependencies, providing a buffer that prevents breakage propagation.
3Productivity
If conventional deployment methods are used, then system updates can be implemented, but complete system restarts are required causing downtime
Solution Approach 1:
The system enables dynamic loading and unloading of model components during runtime. Updated model component files can be loaded without stopping the system, allowing continuous operation during updates and eliminating downtime associated with complete system restarts.
Solution Approach 2:
The system performs preliminary validation and preparation of model component updates before applying them. This includes checking XML schemas and cross-references in advance, so that when updates are deployed hot-swapped, they can be immediately activated without requiring system restart for validation.
Data Source
AI summary
Method and apparatus for representing data for components of a system in respective model components, generating model sub components from model components for at least some of the system components, and accumulating information from the model components and model sub components to determine a world view of the system. In one embodiment, model components can be updated during system operation.
