ash-dal

Create a small inventory management system using Python and the 'ash-dal' package. This system should allow users to manage products in a database, including adding new products, updating product information, deleting products, and listing all products. Additionally, implement a feature that allows searching for products by name or category.

Steps:
1. Set up your development environment with Python and install the 'ash-dal' package.
2. Use 'ash-dal' to define the structure of your database, specifically a table for storing product details such as ID, name, description, price, and category.
3. Implement a Base DAO class provided by 'ash-dal' to handle basic CRUD operations on the product table.
4. Create a command-line interface where users can interact with the inventory management system.
5. Add functionalities to the CLI for adding, updating, deleting, and listing products.
6. Implement a search function that allows users to find products based on their name or category.
7. Ensure data validation is in place for all user inputs.
8. Test the application thoroughly to ensure all functionalities work as expected.

Suggested Features:
- User-friendly CLI prompts guiding users through each action.
- Error handling for invalid user inputs or database errors.
- Option to export the current inventory as a CSV file.
- Basic authentication to restrict access to certain commands.
