Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If non-standardized code authoring is allowed in ETL processes, then ease of manufacture and adaptability are improved, but stability and security deteriorate

Engineering Contradiction:

Improvecode authoring flexibilityVSAvoidcomputing infrastructure stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The compliance system performs preliminary validation of ETL code before execution by checking syntax, semantics, and compliance with predefined standards. This advance checking prevents non-compliant code from being deployed to shared computing infrastructure, thereby maintaining stability while allowing flexible code authoring.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The compliance system acts as an intermediary layer between code authoring and execution. It mediates by validating code against standards and blocking non-compliant code, thus enabling flexible authoring while protecting the stability of the underlying computing infrastructure.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If non-standardized code execution is permitted, then adaptability is improved, but downtime and resource loss increase

Engineering Contradiction:

ImproveETL process customizationVSAvoidsystem downtime

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system performs preliminary compliance checking and validation before ETL code execution. By detecting and preventing issues in advance, it avoids runtime failures that would cause downtime, thus maintaining adaptability while reducing time loss.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If code validation with multiple standards is implemented, then reliability and security are improved, but device complexity increases

Engineering Contradiction:

Improvecode compliance assuranceVSAvoidvalidation system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The compliance checking process is segmented into distinct phases: syntax validation, semantic validation, and standards compliance checking. Each phase handles specific aspects independently, making the overall complex validation process more manageable and maintainable while ensuring comprehensive reliability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The compliance system serves as an intermediary validation layer that implements multiple standards without requiring changes to the underlying ETL execution infrastructure. This modular approach increases reliability through comprehensive checking while containing complexity within the validation layer.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Object-affected harmful factors

If comprehensive compliance checking is performed, then security is improved, but productivity decreases

Engineering Contradiction:

Improvesecurity vulnerability preventionVSAvoidcode deployment speed

Core Design Contradiction:

Object-affected harmful factorsVSProductivity

Solution Approach 1:

Comprehensive compliance checking is performed preliminarily before code deployment to shared infrastructure. By catching security issues in advance rather than during execution, the system ensures security while minimizing the impact on deployment productivity.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system uses lightweight, automated compliance checking mechanisms that can rapidly validate code against multiple standards. These automated checks are designed to be efficient and fast, providing comprehensive security checking without significantly slowing down the deployment process.

AI summary

In some implementations, a device may receive a request to validate code defining a feature for compliance with a feature authoring library. The code may configure one or more phases of an extract, transform, and load (ETL) process associated with obtaining data for the feature. The device may identify one or more standards for assessing whether an initialization or an execution of the one or more phases of the ETL process is indicative of the code complying with the feature authoring library. The device may determine whether the initialization or the execution of the one or more phases of the ETL process satisfies the one or more standards. The device may transmit, based on whether the initialization or the execution of the one or more phases of the ETL process satisfies the one or more standards, a response indicating whether the code complies with the feature authoring library.
