@Krish,
Geometric outdoors a sample eCommerce application has been provided by AEM. You can explore that. I find it very useful for beginners and some of the stuff's are covered.
You may have to begin asking following questions:
- How Hybris product data will be used in AEM website?
- What would be hybris product data modeling considering searching etc?
- How data will be synced between two systems?.
- How to handle user, transactional, third party data?.
Here is the doc which could help you for more details.
