Purpose of this Document

This document provides a logical view of the [System Name] architecture, focusing on the system’s functional structure and organization independent of technical implementation details.

System Structure

Architectural Style: [Layered|Microservices|Monolithic|etc.]
Primary Patterns: [List of key architectural patterns used]

Components:
  Frontend:
    Type: [Technology/framework]
    Pattern: [Design pattern]
    Responsibility: [Key functional area]
  
  Backend:
    Type: [Technology/framework]
    Pattern: [Design pattern]
    Responsibility: [Key functional area]
  
  Data:
    Type: [Technology approach]
    Stores: [Key data repositories]
    Patterns: [Data access patterns]

Key Domain Concepts

Core Entities:
  - Name: [Entity name]
    Purpose: [Brief description]
    Relationships: [How it relates to other entities]
  
  - Name: [Entity name]
    Purpose: [Brief description]
    Relationships: [How it relates to other entities]

Business Processes:
  - Name: [Process name]
    Steps: [Key process steps]
    Actors: [Who/what is involved]
    Data Flow: [Key data elements]

Architecture Layers

    end
    
    subgraph "Backend Layer"
    C[API Gateway]
    D[Services]
    end

Functional Decomposition

    A[System] --> B[Function 1]
    A --> C[Function 2]
    A --> D[Function 3]
    
    B --> B1[Sub-function 1.1]
    B --> B2[Sub-function 1.2]
    
    C --> C1[Sub-function 2.1]
    C --> C2[Sub-function 2.2]
    
    D --> D1[Sub-function 3.1]
    D --> D2[Sub-function 3.2]

Module Organization

@startuml
package "Core Modules" {
    [Security]
    [Logging]
    [Configuration]
}

package "Feature Modules" {
    [Feature A]
    [Feature B]
    [Feature C]
}

package "Support Modules" {
    [Utilities]
    [Common]
    [Testing]
}

[Feature B] --> [Core Modules]
[Feature C] --> [Core Modules]
[Feature A] --> [Support Modules]

Key Interfaces

External Interfaces:
  - Name: [Interface name]
    Purpose: [What it does]
    Exposed To: [Which systems/users]
    Method: [How it's accessed]

Internal Interfaces:
  - Name: [Interface name]
    Purpose: [What it does]
    Provider: [Which component provides it]
    Consumers: [Which components use it]
    Style: [Interface style]

System Behaviors

@startuml
actor User
participant "Frontend" as FE
participant "Backend Service" as BE
database "Database" as DB

User -> FE: Request action
activate FE
FE -> BE: API call
activate BE
BE -> DB: Query data
activate DB
DB --> BE: Return data
deactivate DB
BE --> FE: Response
deactivate BE
FE --> User: Display result
deactivate FE
