- <strong>Customer</strong> class corresponds to entity and table <strong>customer</strong>.
- <strong>CustomerRepository</strong> is an interface extends <strong>CrudRepository</strong>, will be autowired in <strong>CustomerController</strong> for implementing repository methods and custom finder methods.
- <strong>CustomerController</strong> is a REST Controller which has request mapping methods for RESTful requests such as: <code>getAllCustomers</code>, <code>postCustomer</code>, <code>deleteCustomer</code>, <code>deleteAllCustomers</code>, <code>findByAge</code>, <code>updateCustomer</code>.
- Configuration for Spring Datasource and Spring JPA properties in <strong>application.properties</strong>
- <strong>Dependencies</strong> for <strong>Spring Boot</strong> and <strong>MySQL</strong> in <strong>pom.xml</strong>

In this example, we focus on:
- 4 components: <strong><em>customers-list</em></strong>, <strong><em>customer-details</em></strong>, <strong><em>create-customer</em></strong>, <strong><em>search-customer</em></strong>.
- 3 modules: <strong><em>FormsModule</em></strong>, <strong><em>HttpClientModule</em></strong>, <strong><em>AppRoutingModule</em></strong>.
- <strong><em>customer.ts</em></strong>: class Customer (id, firstName, lastName)
- <strong><em>customer.service.ts</em></strong>: Service for Http Client methods
