Java Crudy Orders

A student that completes this project shows that they can:

Perform CRUD operations on an RDBMS JPA and Hibernate (Creating and Updating Records)
Perform CRUD operations on an RDBMS JPA and Hibernate (Updating certain fields in records)
Perform CRUD operations on an RDBMS JPA and Hibernate (Deleting records)
Understand and implement @Transactional annotation

Introduction

This is Part 3 of a 3 Part project.

Part 1 can be found at java-orders
Part 2 can be found at java-getorders

This is a basic database scheme with customers, orders, and sales agents. This Java Spring REST API application will provide endpoints for clients to manipulate various data sets contained in the application's data.

Database layout

The table layouts are as follows

AGENTS
- AGENTCODE primary key, not null Long
- AGENTNAME string
- WORKINGAREA string
- COMMISSION double
- PHONE string
- COUNTRY string
CUSTOMERS
- CUSTCODE primary key, not null Long
- CUSTNAME String, not null
- CUSTCITY String
- WORKINGAREA String
- CUSTCOUNTRY String
- GRADE String
- OPENINGAMT double
- RECEIVEAMT double
- PAYMENTAMT double
- OUTSTANDINGAMT double
- PHONE String
- AGENTCODE Long foreign key (one agent to many customers) not null
ORDERS
- ORDNUM primary key, not null Long
- ORDAMOUNT double
- ADVANCEAMOUNT double
- CUSTCODE Long foreign key (one customer to many orders) not null
- ORDERDESCRIPTION String
PAYMENTS
- PAYMENTID primary key, not null long
- TYPE String not null
ORDERSPAYMENTS (join table)
- ORDERNUM foreign key to ORDERS
- PAYMENTID foreign key to PAYMENTS.
Customers has a foreign key to Agents (AGENTCODE) this means:
- Customers has a Many to One relationship to Agents and
- Agents has a One to Many relationship to Customers
Orders has a foreign key to Customers (CUSTCODE)
- Orders has a Many to One relationship to Customers and
- Customers has a One to Many relationship to Orders
Orders has a many to many relationship with payments
- multiple orders can use the same payment type and an order can have multiple payment types.
- For example you can use both gift card and credit card to pay for an order.

Using the provided seed data, a successful application will return the follow data based on the given endpoint. Expand the section of the endpoint to see the data that is returned. The first set of endpoints that read data were developed for the first part of the project. Your task is to add the second set of endpoints which manipulate the data.

MVP - MANIPULATING DATA new endpoints to add

Instructions

Please fork and clone this repository. Copy your solution from part 2 into this repository. Your solution from part 2 is the starting point for part 3. If your part 2 did not reach MVP, please check with your TL group leader about your options. Regularly commit and push your code as appropriate.

Expose the following endpoints

POST /customers/customer - Adds a new customer including any new orders
PUT /customers/customer/{custcode} - completely replaces the customer record including associated orders with the provided data
PATCH /customers/customer/{custcode} - updates customers with the new data. Only the new data is to be sent from the frontend client.
DELETE /customers/customer/{custcode} - Deletes the given customer including any associated orders
POST /orders/order - adds a new order to an existing customer
PUT /orders/order/{ordernum} - completely replaces the given order record
DELETE /orders/order/{ordernum} - deletes the given order

Stretch Goal

Rename your project and associated packages and files from orders, or what you called your orders, to crudyorders, or what you would like to call your crudyorders project.
DELETE /agents/unassigned/{agentcode} - Deletes an agent if they are not assigned to a customer

MVP Testing

Note that your ids may vary!
