The document outlines the steps for installing Eclipse and importing existing projects, particularly focusing on domain-specific languages (DSL). It provides a sample DSL code for a 'customer' class demonstrating serialization and relationships with other classes. Additionally, it touches on DSL workbench tools and resources for further information.

1. Software Installation
• Unzip the Eclipse distribution matching your OS
Windows users: Use a location close to the root directory
• Run the Eclipse executable
• Choose File -> Import -> Existing projects into workspace
• Select Archive file and choose workspace.zip from the USB
stick

(DSL)

7. Domain-specific Language
(DSL)
a formal, processable language
targeting at a specific viewpoint
or aspect of a system.

8. Example: JPA

9. @Entity
public class Customer implements Serializable {
private Long id;
private String name;
private Address address;
private Collection<Order> orders = new HashSet<Order>();
private Set<PhoneNumber> phones = new HashSet<PhoneNumber>();
public Customer() {}
@Id
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Address getAddress() {
return address;
}
public void setAddress(Address address) {
this.address = address;
}
@OneToMany
public Collection<Order> getOrders() {
return orders;
}
public void setOrders(Collection<Order> orders) {
this.orders = orders;
}
@ManyToMany
public Set<PhoneNumber> getPhones() {
return phones;
}
public void setPhones(Set<PhoneNumber> phones) {
this.phones = phones;
}
}

10. @Entity
public class Customer implements Serializable {
private Long id;
private String name;
private Address address;
private Collection<Order> orders = new HashSet<Order>();
private Set<PhoneNumber> phones = new HashSet<PhoneNumber>();
public Customer() {}
@Id
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return name;
} entity Customer {
public void setName(String name) {
this.name = name;
String name
} Address address
public Address getAddress() {
return address; Order* orders
}
public void setAddress(Address address) {
PhoneNumber** phones
this.address = address; }
}
@OneToMany
public Collection<Order> getOrders() {
return orders;
}
public void setOrders(Collection<Order> orders) {
this.orders = orders;
}
@ManyToMany
public Set<PhoneNumber> getPhones() {
return phones;
}
public void setPhones(Set<PhoneNumber> phones) {
this.phones = phones;
}
}
