SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) and assets (resource) components.

What problem does it solve?

This Skill guides developers through creating pragmatic and scalable backend architectures tailored to federal system standards, ensuring security and maintainability.

Core Features & Use Cases

  • Architecture Decision-Making: Helps determine when to choose monolith or microservices based on team size, domain complexity, and operational maturity.
  • Project Structure Setup: Provides detailed setup templates for Python/Flask and Node.js/Express modular monolith projects, emphasizing clean module boundaries.
  • Database & Schema Design: Recommends best practices for relational databases like SQL Server and PostgreSQL, including audit fields, normalization, and security features.
  • Business Logic & Validation: Advocates for business rule validation in application code with examples, supporting compliance and change management.
  • Service Extraction & Modularization: Offers step-by-step guidance for transitioning from monolith to microservices, when justified.
  • Audit & Security: Emphasizes importance of audit trails, soft delete, and validation layers to preserve system integrity and compliance.
  • Error Handling & Patterns: Demonstrates structured error management, versioning, and avoiding premature abstraction to optimize development effort.

Quick Start

Initialize a modular project in Python using Flask by creating structured domain modules with clear APIs and shared utilities, then implement business logic in service layers, enforcing validation and audit mechanisms for scalable development.

Frequently Asked Questions about backend-architecture

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I structure a modular monolith in Flask or Express for a federal application?▼

Structure a modular monolith by creating domain modules with clear APIs and shared utilities. Implement business logic in service layers, enforcing validation and audit mechanisms to ensure scalable development and maintainability.

When should I choose microservices over a monolith for my backend architecture?▼

Choose microservices over a monolith based on team size, domain complexity, and operational maturity. Transition from a monolith only when justified by specific scaling needs and service extraction requirements.

What are the best practices for relational database schema design in PostgreSQL and SQL Server?▼

Relational database schema design best practices include using audit fields, normalization, and security features. Apply these strategies in PostgreSQL or SQL Server to preserve data integrity and maintain compliance.

How do I implement business rule validation in application code for compliance?▼

Implement business rule validation in application code by enforcing rules within service layers. This approach supports compliance and change management while preventing premature abstraction to optimize development effort.

How do I manage audit trails and security in a scalable backend system?▼

Manage audit trails and security by implementing audit fields, soft delete, and validation layers. These mechanisms preserve system integrity and ensure compliance in scalable backend architectures.

Does this backend architecture approach support structured error management and versioning?▼

This backend architecture approach supports structured error management and versioning. It demonstrates patterns for avoiding premature abstraction, optimizing development effort while maintaining system resilience.
