7. Some Typical Situations
in
Software Development

8. Boring code

9. Accidental complexity

10. Wrong level of abstraction

11. Anatomy of Modern Software
Software artifact

12. Anatomy of Modern Software
manually written code Frameworks
Libraries

13. Anatomy of Modern Software
manually written
code
Frameworks
schematic code (manually written)
Libraries

14. The Result?

15. More and more code to write

16. More and more code to write

17. More and more code to write

18. Problems

19. Problems

20. Problems
Can we solve them with models?

21. Yes, we can!

22. Code Generation Helps
Model
manually written
code
Generator
Frameworks
schematic code (generated)
Libraries

23. MDSD

25. Demo

27. @SuppressWarnings("serial")
@Entity
@Table(name = "CUSTOMER_INFO")
public class CustomerInfo implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "idSeq")
@SequenceGenerator(name = "idSeq", sequenceName = "CUST_SEQ", allocationSize = 1)
@Column(name = "CUST_ID", nullable = false)
private String customerId;
public void setCustomerId(String customerId) {
this.customerId = customerId;
}
public String getCustomerId() {
return customerId;
}
@Column(name = "EMAIL", nullable = false, length = 128)
private String emailAddress;
public String getEmailAddress() {
return emailAddress;
}
public void setEmailAddress(String emailAddress) {
String oldValue = emailAddress;
this.emailAddress = emailAddress;
firePropertyChangedEvent("emailAddress", oldValue, this.emailAddress);
}

28. @SuppressWarnings("serial")
@Entity
@Table(name = "CUSTOMER_INFO")
public class CustomerInfo implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "idSeq")
@SequenceGenerator(name = "idSeq", sequenceName = "CUST_SEQ", allocationSize = 1)
@Column(name = "CUST_ID", nullable = false)
private String customerId;
public void setCustomerId(String customerId) {
this.customerId = customerId;
}
public String getCustomerId() {
return customerId;
}
@Column(name = "EMAIL", nullable = false, length = 128)
private String emailAddress;
public String getEmailAddress() {
return emailAddress;
}
public void setEmailAddress(String emailAddress) {
String oldValue = emailAddress;
this.emailAddress = emailAddress;
firePropertyChangedEvent("emailAddress", oldValue, this.emailAddress);
}

29. entity CustomerInfo
(id=CUST_ID, sequenceName=CUST_SEQ)
{
String emailAddress (notNull, length = 128)
}

30. entity CustomerInfo
(id=CUST_ID, sequenceName=CUST_SEQ)
{
String emailAddress (notNull, length = 128)
}
Bean
DAO
(POJO)
