Exercise 2: Stock Keeping

Description

• Create an application to manage stock keeping for products. The application should keep track of products, their management, and journal entries for stock transactions.
• Products have a name, producer, and sale price. Management entities are identified by name.
• Each journal entry records stock entries and exits along with their values, linked to specific products and management entities.
• Management journal labels can be "Entry" or "Exit".

Tasks

• product/management/management_journal: Add, Edit, Delete.
• Create a catalog for entities: "product", "management".
• Create event listeners for tables that needs validations (e.g., adding a product without a name, journal entry without stock values, etc., should not be allowed):
• Add a new entity action at the journal level "Revert journal entry":
  • It will revert the stock values of a journal entry (it will create a new management journal entry with the opposite effects);
  • A journal entry cannot be reverted if it results in negative stock → warning message.
• Sales report: situation of sales over a period (total profit, management details).
• Product sales report: situation of product sales over a period (total profit, product details).
• Interval sales evolution report: track sales evolution per product on a specific interval.
• Stock report: stock situation per management entity as of a specific date.
• Management journal report: journal entries per each label and management entity.
