attack-on-domain

Develop a fully functional mini-application named 'DomainWarrior' using the Python package 'attack-on-domain'. DomainWarrior is designed to manage different domains of knowledge within a company, ensuring each domain is well-defined and isolated from others. This application will help in organizing and validating data across various business contexts, making it easier to manage complex systems.

### Features:
1. **Domain Definition**: Allow users to define their own domains (e.g., HR, Finance, Sales), each with its own set of rules and validations.
2. **Entities Management**: Within each domain, users can define entities (e.g., Employee in HR, Invoice in Finance) along with their attributes and relationships.
3. **Value Objects**: Users can create value objects that represent meaningful values in their domains (e.g., Currency, DateRange).
4. **Bounded Contexts**: Ensure that each domain is treated as a bounded context, meaning that it has its own model and rules that are not influenced by other domains.
5. **Validation Helpers**: Implement robust validation mechanisms for entities and value objects based on user-defined rules.
6. **User Interface**: Provide a simple and intuitive command-line interface for adding, modifying, and querying domains, entities, and value objects.
7. **Documentation and Help**: Include comprehensive documentation and help options within the application.

### Utilizing 'attack-on-domain':
- Use the package's entity and value object classes to define your custom domain-specific models.
- Leverage the validation helpers provided by 'attack-on-domain' to enforce business rules and ensure data integrity.
- Apply the concept of bounded contexts to isolate domain definitions and prevent conflicts between different areas of the business.

### Steps to Develop DomainWarrior:
1. **Setup Project**: Initialize a new Python project and install the 'attack-on-domain' package.
2. **Define Domains**: Create classes representing different domains using 'attack-on-domain' features.
3. **Manage Entities and Value Objects**: Define entities and value objects within each domain, utilizing the package's capabilities.
4. **Implement Validation**: Set up validation rules for entities and value objects to maintain data consistency.
5. **Build UI**: Develop a command-line interface for interacting with the application.
6. **Testing**: Write tests to ensure that all functionalities work as expected.
7. **Documentation**: Prepare documentation detailing how to use the application and customize it for specific needs.
8. **Deployment**: Package the application for easy distribution and deployment.
