Application Configuration Upgrade via Version Detection and XSLT Transformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user interface configurations for applications are not easily upgradable when new versions of patterns are introduced, requiring manual updates and storage of upgraded configurations, which can be cumbersome and inefficient.
Innovation Solution
Implementing a method to automatically upgrade configuration specifications by comparing version numbers and using XSLT to transform XML trees, allowing incremental upgrades and reusing upgrade modules, thus eliminating the need for direct upgrade modules for each configuration and pattern combination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual updates are used to upgrade configurations when new pattern versions are introduced, then configuration compatibility is maintained, but the upgrade process becomes cumbersome and inefficient
Solution Approach 1:
The system performs preliminary actions by automatically detecting configuration versions and applying appropriate upgrade modules before the configuration is used, eliminating the need for manual intervention and making the upgrade process transparent to users
Solution Approach 2:
The configuration upgrade system serves itself by automatically identifying which upgrade modules are needed based on version comparisons and applying them without external assistance, making the process efficient and self-managing
2Reliability
If upgraded configurations are stored for future use, then upgrade results are preserved, but storage requirements increase
Solution Approach 1:
Instead of storing upgraded configurations permanently, the system creates temporary copies during the upgrade process and discards them afterward, maintaining reliability through version tracking while minimizing storage requirements
Solution Approach 2:
The system discards intermediate upgrade artifacts after they serve their purpose, recovering storage space while maintaining configuration integrity through version number verification and selective regeneration
3Adaptability or versatility
If direct upgrade modules are created for each configuration and pattern combination, then complete upgrade coverage is achieved, but the number of required modules increases exponentially
Solution Approach 1:
The upgrade system is segmented into modular components where upgrade modules operate independently on specific configuration elements rather than requiring complete configuration-pattern pairs, dramatically reducing the total number of modules needed
Solution Approach 2:
Upgrade modules are designed with universality to handle multiple configuration types and pattern versions through standardized interfaces and version detection logic, allowing a single module to serve multiple purposes across different configuration-scenario combinations

AI summary
Methods and systems, including computer program products, implementing techniques for upgrading pattern configurations. The techniques include receiving configuration for a pattern, determining whether the configuration is current with respect to the pattern, automatically upgrading the configuration if the configuration is not current, and using the configuration to modify one or more predefined elements of an application.
