Graph-Based Software Generation for Complex Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of modern computer systems, such as SAAS, increases the time and likelihood of software bugs when updating functionality, as changes in one part of the system may require updates in multiple interdependent components, leading to significant development challenges and reliability issues.
Innovation Solution
The automatic generation of executable software using a task specification and a graph of properties and components, where each component processes input properties to produce output properties, allowing for efficient regeneration of software when system components change, such as APIs, reducing the burden on developers and improving system reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual software updating is used in complex computer systems, then developers have control over changes, but the time required for implementation increases and bugs increase
Solution Approach 1:
The system performs self-updating through automatic code generation. When a database schema changes, the system automatically generates and applies the necessary migration code without requiring manual developer intervention for each change, enabling the system to serve its own maintenance needs
Solution Approach 2:
The system pre-generates migration code templates and structures before actual database changes occur. By having migration templates ready in advance and automatically applying them when changes are detected, the system prepares the necessary update mechanisms beforehand rather than creating them during the update process
2Reliability
If manual software updating is used in complex computer systems, then developers can review changes, but the likelihood of bugs increases due to missed updates
Solution Approach 1:
The system implements feedback loops that automatically detect database schema changes and trigger corresponding migration code generation. The system monitors for changes, automatically responds by generating appropriate migration code, and verifies application, creating a closed-loop system that reduces human error in updating complex interdependent components
Solution Approach 2:
An automatic code generation system acts as an intermediary between database schema changes and the application code. This intermediary automatically translates schema changes into the necessary migration code, eliminating the need for developers to manually update each dependent component and reducing bugs from missed updates
3Productivity
If automatic code generation is implemented, then software development time decreases, but the complexity of the generation system increases
Solution Approach 1:
The code generation system is divided into separate, modular components: a template definition module, a code generation engine, and a migration execution module. Each component handles a specific aspect of the generation process, making the overall complex system manageable through clear separation of concerns and independent development of each segment
Data Source
AI summary
Software for a computer system may be automatically generated to reduce costs. Software may be automatically generated using a set of software components where each component may have one or more input properties and one or more output properties. A property may correspond to a type of data (e.g., a customer ID) used by the computer system. A graph may be created from the components where the graph includes component nodes for the components and property nodes for the input and output properties. To automatically generate software for a task, a task specification may be received that includes a task input property and a task output property. A path on the graph may be determined from the task input property and the task output property, and software for accomplishing the task may be generated using components on the path. The software may then be executed or stored for later execution.
