Source Code Translation via Intermediate Representation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual translation of source code from legacy platforms to modern cloud-based systems is complex, time-consuming, and error-prone, especially when migrating ETL code, requiring significant human intervention and leading to inconsistencies due to different coding styles and logic.
Innovation Solution
A system and method for automatically translating source code by parsing input code into an intermediate representation based on an abstraction model, optimizing it, and formatting it into output code compatible with a target platform, reducing the need for manual translation and minimizing human intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual translation of source code is performed by skilled developers, then the translation can be completed with knowledge of both source and target vendor systems, but the process becomes complex, time-consuming, resource intensive, and error-prone due to multiple developers applying different coding styles and logic
Solution Approach 1:
The patent introduces an intermediate representation (IR) as a mediator between source code and target code. The source code is first translated into an IR format that captures the semantic meaning and structure, which then serves as a platform-independent intermediate form that can be systematically transformed into various target languages. This intermediary step standardizes the translation process and eliminates variability introduced by different developers' coding styles.
Solution Approach 2:
The translation process is segmented into distinct phases: source code parsing into IR, IR optimization, and IR transformation to target code. Each phase is handled by specialized components (parsers, optimizers, code generators) that can be independently developed and maintained. This segmentation allows for more reliable and maintainable translation systems while reducing the time required for complete translation tasks.
2Adaptability or versatility
If manual translation is performed to handle multiple source ETL formats and translate them to target ETL formats, then comprehensive translation capability is achieved, but the complexity increases significantly requiring collaboration between many skilled developers
Solution Approach 1:
The intermediate representation serves as a universal format that can represent multiple source ETL formats and translate to multiple target ETL formats through a single unified system. The IR captures the essential semantic structure of ETL operations in a platform-independent manner, allowing the same IR to be transformed into various target languages (SQL, Python, Java, etc.) without requiring separate translation paths for each source-target combination.
Solution Approach 2:
The IR acts as a universal intermediary that decouples source format complexity from target format requirements. By translating all source formats into this common intermediate form first, the system manages complexity centrally in the IR definition rather than distributing it across multiple developer-specific translation rules, thereby achieving versatility without proportional increases in system complexity.
3Ease of manufacture
If lift-and-shift migration is used to replicate source application exactly on target cloud platform, then cost-effectiveness is achieved, but the migrated application does not optimize to take full advantage of the new cloud environment
Solution Approach 1:
The system transforms the application code by changing its structural parameters to match the target cloud platform's optimal execution model. The IR representation allows for optimization passes that restructure queries, adjust data access patterns, and modify computational logic to leverage cloud-specific features such as distributed computing, parallel processing, and cloud-native data formats, thereby improving performance without requiring complete manual rewriting.
4Productivity
If complete rewriting of data pipeline is performed into target vendor system codebase, then optimization for target system is achieved, but manual translation requires significant human intervention and introduces inconsistencies
Solution Approach 1:
The intermediate representation serves as a consistent intermediary that ensures translation consistency across different target platforms. By translating to IR first using standardized parsing rules, then from IR to target code using platform-specific code generators, the system maintains reliability through centralized semantic validation in the IR phase while allowing each target generator to optimize for its specific platform without introducing inconsistencies.
Data Source
AI summary
A system and method for migrating data management code converts input source code compatible with a source platform to output source code compatible with a target platform. The source code is parsed to generate an intermediate representation of the input source code based on an abstraction model. The abstraction model is structured to include one or more workflows, with each workflow including data manipulation units and/or execution plans for controlling the execution of activities contained therein. The intermediate representation is formatted into the output source code. The output source code may be packaged for deployment on the selected one of the one or more target platforms.
