Some Typical Situations in
Software Development
Boring code
Accidental complexity
Wrong level of abstraction

The Result?
More and more code to write

Can we solve them with models?

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); }
