tomevault-io Architecture Document Structure (Core)
[!NOTE] This is the CORE template for architecture documents. For full examples with JSON samples, diagrams, and detailed sections, load
architecture-format-extended.
Your architecture must contain the following sections:
1. Task Description
Link to TASK and brief summary of requirements.
2. Functional Architecture
Description of the system in terms of functions it performs.
2.1. Functional Components
For each functional component describe:
Component Name: [Example, "User Management"]
Purpose: [Why this component is needed]
Functions:
- Function 1: [Description]
- Input: [what accepts]
- Output: [what returns]
- Related Use Cases: [UC-01, UC-03]
Dependencies:
- Depends on which other components
- Which components depend on it
2.2. Functional Components Diagram
[Mermaid diagram showing connections between components]
3. System Architecture
Description of the system in terms of physical/logical components.
3.1. Architectural Style
Which architectural pattern is used:
- Monolith
- Microservices
- Layered Architecture
- Event-driven
- Etc.
Justification: [Why this style was chosen]
3.2. System Components
For each system component describe:
Component Name: [Example, "User Service"]
Type: [Backend service / Frontend / Database / Message Queue / etc.]
Purpose: [Why needed]
Implemented Functions: [Links to functions from functional architecture]
Technologies: [Programming language, frameworks]
Interfaces:
- Inbound: [Who and how accesses this component]
- Outbound: [Who and how this component accesses]
Dependencies:
- External libraries
- Other system components
- External services
3.3. Components Diagram
[Mermaid diagram showing components and their interaction]
4. Data Model (Conceptual)
Description of data structure in the system at a high level.
4.1. Entities Overview
Entities:
Entity: [Name, e.g., "User"]
Description: [What this entity represents]
Key Attributes:
id(UUID) — unique identifier- [Other key attributes]
Relationships:
- [Entity relationships, e.g., One User has many Sessions (1:N)]
Business Rules:
- [Key business rules for this entity]
[!TIP] For detailed logical data model with table schemas, indexes, and NoSQL examples, load
architecture-format-extended.
