The current system lacks the functionality to search for inventory based on a store ID.
A new endpoint needs to be added to the inventory controller to facilitate this search capability.
The inventory service must be extended with a new method to retrieve all inventory items associated with a specific store ID.
This feature will allow users to query inventory data filtered by store, enhancing the usability of the Order Management System.
Solution Plan:
I reviewed multiple solutions and picked the following solution.
The best solution is to add a custom query method in the InventoryRepository interface to find inventory by store ID using Spring Data JPA's query derivation mechanism. This approach is simple, requires minimal changes, and leverages Spring Data JPA's capabilities for optimized query execution.
Here is why I selected the above solution:
This solution is the best because it adheres to the principles of simplicity and minimalism. By using Spring Data JPA's query derivation, we avoid writing explicit SQL queries, which reduces complexity and potential errors. It also ensures that the query is optimized by the underlying JPA provider, Hibernate, for performance and accuracy.
Implementation Plan:
Open the file com/oms/repository/InventoryRepository.java located in src/main/java.
Add the method signature List findByStoreId(String storeId); to the InventoryRepository interface.

Here is how I approached the problem.
Problem Summary:
The current system lacks the capability to search for inventory based on a specific store ID.
A new endpoint needs to be added to the inventory controller to facilitate this search functionality.
A corresponding method should be implemented in the inventory service to retrieve all inventory items associated with a given store ID.
This feature will enhance the Order Management System by allowing users to query inventory data more efficiently.
The implementation should ensure that the new endpoint and service method are integrated seamlessly with existing components.
Solution Plan:
I reviewed multiple solutions and picked the following solution.
The best solution is to add a new method in InventoryService that calls a custom query from InventoryRepository, handling exceptions and edge cases. This approach is simple and directly addresses the task requirements.
Here is why I selected the above solution:
This solution is the best because it adheres to the principles of simplicity and minimal change. By adding a single method to InventoryService, we maintain the existing structure and responsibilities of the class while fulfilling the task requirements. It avoids unnecessary complexity and changes to other parts of the system.
Implementation Plan:
Add a new method executeCustomQuery in the InventoryService class.
Within the method, use a try-catch block to handle potential exceptions during query execution.
Use the existing Logger instance to log any exceptions that occur.
Return the result of the query, and handle edge cases such as null or empty results by returning an appropriate response.

Description:
Here is how I approached the problem.
Problem Summary:
There is a need to enhance the inventory management functionality by allowing users to search for inventory based on a specific store ID.
This requires the addition of a new endpoint in the Inventory Controller to handle HTTP requests for inventory retrieval by store ID.
A corresponding method must be implemented in the Inventory Service to perform the logic of fetching inventory data from the database using the provided store ID.
The feature should ensure that the correct inventory data is retrieved and returned in a structured format, likely JSON.
The implementation should consider potential edge cases, such as invalid store IDs or stores with no inventory.
Solution Plan:
I reviewed multiple solutions and picked the following solution.
The solution involves adding a new endpoint in the InventoryController to handle GET requests for fetching inventory by store ID. This is achieved by adding a new method in the InventoryController class, ensuring it is documented with JavaDoc, and writing a test case to verify its functionality.
Here is why I selected the above solution:
This solution is the best because it adheres to the principles of simplicity and minimal change. It only involves updating the InventoryController, which is the most relevant class for handling inventory-related requests, and ensures the new functionality is tested and documented.
Implementation Plan:
Add a new method fetchInventoryByStoreId in InventoryController to handle GET requests for inventory by store ID.
Use @GetMapping(/{storeId}) annotation to map the endpoint with a path variable for store ID.
Inject InventoryService to fetch inventory data based on store ID.
Document the new method with JavaDoc to describe its purpose and usage.
Create a test case in the corresponding test file to verify the new endpoint's functionality.
Ensure the test case checks for correct HTTP status and response data.

A new endpoint needs to be added to the inventory controller to facilitate this search.
A corresponding method should be implemented in the inventory service to retrieve inventory data based on the store ID.
This feature will enable users to query inventory specific to a particular store, enhancing the system's usability.
The implementation should ensure that the search is efficient and returns accurate results.
Solution Plan:
I reviewed multiple solutions and picked the following solution.
The solution involves integrating changes across the Inventory module and conducting end-to-end testing to ensure the new feature works as expected. This approach ensures that the Inventory module functions seamlessly within the Order Management System.
Here is why I selected the above solution:
This solution is the best because it focuses on integrating and testing the Inventory module, which is central to the application's functionality. By conducting end-to-end testing, we ensure that the module works correctly within the entire system, minimizing the risk of integration issues.
Implementation Plan:
Verify the integration of InventoryController, InventoryService, and InventoryRepository by checking method calls and data flow.
Ensure Inventory entity and InventoryRequestDto are correctly used by reviewing their usage in the module.
Conduct end-to-end testing by running InventoryServiceTest to verify fetchInventory and createInventory methods.
Check logs generated by Logger class to ensure all operations are logged correctly.
Deploy the application on a local Tomcat server for manual testing of Inventory endpoints.
Review test results and logs to confirm seamless functionality within the Order Management System.
