# Sample References Domain

## Sample Implementation Showcase

This collection presents both built implementations and reference designs demonstrating how FlexBase can be used to rapidly develop business applications across various domains. These examples showcase how domain models, workflows, role-based access control, and complete business logic can be implemented efficiently using FlexBase patterns.

The applications below—whether fully built implementations or comprehensive reference guides—represent just a few of the countless domains FlexBase can handle. They serve as blueprints showing how to leverage FlexBase's architectural foundation to bring your vision to life faster than traditional approaches.

These examples are designed to demonstrate:

* **Rapid development** - How entire business domains can be implemented quickly
* **Comprehensive coverage** - Complete workflows, access control, and business logic patterns
* **Best practices** - Enterprise-grade architectural patterns and implementations
* **Adaptability** - Domain models that flex to fit various business needs

FlexBase's power lies in its ability to handle **any domain implementation** with exceptional speed and sophistication. Whether you need a full implementation or a reference guide for your specific domain, FlexBase provides the elegant framework to accelerate development and deliver production-ready solutions.

## Sample Applications

* [Collection App](/sample-references-domain/collection-app.md) - Collection management system for organizing and tracking items
* [Chat App](/sample-references-domain/chat-app.md) - Real-time chat application with messaging, reactions, and group management
* [Audit App](/sample-references-domain/audit-app.md) - Comprehensive audit management system with workflows, evidence collection, and role-based access control

## Implementation Guide for BAs (How to express requirements for Flexbase)

* **Map features to modules**: For each requirement, identify the module (e.g., JobPostings, Candidates) and the controller action (Create, Publish, Approve...).
* **Define states and transitions**: For each entity, list states, allowed actions, and the exact roles allowed per action. This directly drives Flexbase state classes and RBAC checks.
* **Capture approval steps**: Specify step order, required roles/permissions, mandatory vs optional, timeouts, and escalation roles. These populate approval process configuration.
* **Specify validation & data**: Enumerate required fields, constraints (ranges, lengths, uniqueness), and important indexes per entity. These become annotations and DB indexes.
* **List API surface**: For each action, define HTTP verb, route, request DTO fields, and expected outcomes. Flexbase generates these endpoints.
* **Identify domain events**: Note the business events to emit (e.g., JobPostingCreated, OfferApproved). Used for audit and subscribers.
* **Set configuration rules**: Note any conditional/automatic transitions (e.g., auto-publish for high-priority IT roles). These go into workflow configuration.
* **Access matrix**: Provide a concise role-to-action matrix per state. This is the source of truth for RBAC enforcement.
* **Test scenarios**: Include positive/negative role tests and end-to-end state progression checks. These become automated tests.
* **UI touchpoints (if applicable)**: Outline needed screens (lists, detail, approval screens) to align with generated APIs.
