Create Domain Models

Initial ideas:

• User model (id, name, email etc)
• Recepie (id, user_id, title, description, steps, ingredients, categories)
• Ingredients (ean)
• Category (id, name)

Creating domain models is a foundational step in software development, providing a conceptual framework that captures the various entities, their attributes, and relationships within the system being developed. Here is a user story to encapsulate the task of creating domain models:

Title: Develop Comprehensive Domain Models for System Architecture

As a Software Architect,

I want to create detailed domain models for our project,

So that the development team has a clear understanding of the system's structure, the relationships between different parts of the domain, and how data flows within the system, facilitating a more informed and efficient development process.

Acceptance Criteria:

1. Identify Key Entities: Collaborate with stakeholders, including domain experts, business analysts, and the development team, to identify the key entities within the system's domain, such as users, products, transactions, etc.
2. Define Attributes and Relationships: For each entity, define its attributes (e.g., name, ID, description) and the relationships between entities (e.g., one-to-many, many-to-many). This includes understanding how entities interact with each other and any dependencies.
3. Create Visual Diagrams: Use UML (Unified Modeling Language) or similar tools to create visual diagrams of the domain model. These diagrams should clearly depict entities, their attributes, and their relationships, providing a graphical representation of the system architecture.
4. Incorporate Business Rules: Ensure that the domain model accurately reflects the business rules and logic that govern the system. This includes constraints, hierarchies, and any other rules that affect how entities relate and interact.
5. Review and Validate with Stakeholders: Present the domain models to stakeholders and domain experts for review and validation. This step ensures that the models accurately represent the business domain and meet the project's requirements.
6. Iterate Based on Feedback: Refine and update the domain models based on feedback from stakeholders and the development team. This iterative process helps to clarify any ambiguities and ensure the models are as accurate and comprehensive as possible.
7. Documentation and Communication: Document the domain models thoroughly, including descriptions of entities, attributes, relationships, and business rules. Share this documentation with the development team to ensure a shared understanding of the system's domain.
8. Use as a Foundation for Development: Utilize the domain models as a foundational reference throughout the development process. This includes guiding the database design, informing the development of business logic, and ensuring that the software architecture aligns with the domain structure.

Outcome: The creation of detailed domain models will provide a crucial conceptual foundation for the entire development process, ensuring that the software is built with a clear understanding of the domain structure, business rules, and data relationships. This facilitates better-informed design decisions, more efficient development, and a system that accurately reflects the needs and complexities of the domain it represents.
