[WIP] Create Complete Software Requirements Specification for EMR Backend System

[Copilot]

Thanks for asking me to work on this. I will get started on it and keep this PR's description up to date as I form a plan and make progress.

Original description:

Software Requirements Specification (SRS) for EMR Backend System

Create a comprehensive Software Requirements Specification document for the EMR (Electronic Medical Record) backend system. The document should provide complete technical specifications that enable a developer to build the entire Laravel 12 backend system without needing access to database migrations or other reference materials.

Requirements

Document Structure

The SRS document should include:

1. Introduction & Overview

   • System purpose and scope
   • Target audience (Cambodia healthcare system)
   • Technology stack specifications

2. System Architecture

   • Overall system design
   • Laravel 12 framework requirements
   • Database design specifications
   • API architecture patterns

3. Functional Requirements

   • Complete feature specifications
   • User roles and permissions
   • Business logic requirements
   • Data validation rules

4. Technical Requirements

   • Database schema specifications
   • API endpoint definitions
   • Authentication and authorization
   • Data models and relationships

5. Implementation Guidelines

   • Coding standards
   • Testing requirements
   • Security considerations
   • Performance requirements

6. Data Models Specification

   • Complete entity definitions
   • Relationship mappings
   • Field specifications with types and constraints
   • Business rules for each entity

Key System Components to Document

Based on the database structure, the system includes:

• Master Data Management: Terminologies, Concepts, Gazetteers
• Healthcare Facility Management: Organizations, Facilities, Departments, Rooms, Services
• Patient Management: Patient demographics, addresses, identities, cards
• Clinical Workflow: Visits, Encounters, Observations, Conditions
• Medication Management: Requests, instructions, dispensing
• Service Management: Laboratory, imaging, procedures
• Financial Management: Invoicing and billing
• Staff Management: Practitioners and their qualifications

Technical Specifications Required

• Laravel 12 framework implementation
• RESTful API design patterns
• Database schema with complete field specifications
• Eloquent model relationships
• Migration specifications
• Seeder requirements
• Validation rules
• API endpoint documentation
• Authentication system (likely Sanctum)
• Authorization policies
• Error handling patterns
• Logging requirements

Cambodia-Specific Requirements

• Khmer language support
• Local healthcare regulations compliance
• Administrative division structure (Province, District, Commune, Village)
• Local healthcare facility hierarchies
• Cambodia-specific medical coding systems

Deliverables

1. Main SRS Document (SOFTWARE_REQUIREMENTS_SPECIFICATION.md)

   • Complete technical specification
   • Database schema documentation
   • API endpoint specifications
   • Business logic requirements

2. Database Design Document (DATABASE_DESIGN.md)

   • Entity relationship diagram descriptions
   • Table specifications with all fields
   • Relationships and constraints
   • Indexing strategies

3. API Documentation (API_SPECIFICATION.md)

   • Complete endpoint definitions
   • Request/response schemas
   • Authentication requirements
   • Error response formats

4. Implementation Guide (IMPLEMENTATION_GUIDE.md)

   • Step-by-step development approach
   • Laravel setup instructions
   • Testing strategies
   • Deployment considerations

Success Criteria

The SRS should be comprehensive enough that a Laravel developer can:

• Set up the complete backend system
• Implement all required features
• Understand the business logic
• Create proper database structure
• Build secure and scalable APIs
• Handle Cambodia-specific requirements

The documentation must be detailed, clear, and actionable for Cambodia's healthcare system context.
