Event Sourcing

An example of using EventSourcing pattern in a real project. Implementation of this pattern may contains some flaws.

This is an example of the online shop.

The scenario

1. User registers himself in the shop
2. Email is send to to the user's email
3. User accepts the invitation
4. User's account is activated
5. User logs in
6. User finds a product 'Milk'
7. User adds 2 pieces of milk to the basket
8. User finds a product 'Bread'
9. User adds 1 piece of bread to the basket
10. User finds a product 'Butter'
11. User adds 3 pieces of butter to the basket
12. User changes the quantity of the butter for 1
13. User removes bread from the basket
14. User logs out
15. User logs in
16. User tries to find a non-existent product called 'Cookies'
17. User creates the Order
18. Basket is closed
19. Send email with the order

System capabilities

1. Command can cause the series of command executes. E.g. CloseOrderCommand calls CloseBasketCommand and SendEmailCommand.
2. We want to know what products users searched for and found none.

TODO

1. DI Container
2. DBAL
3. DDD
