Figure 9-1. My Documents Relationships
Figure 9-1 shows how the Model classes are related to each other. The Documents table has a one-to-one
relationship with its document type (Types table), and the Users table has a many-to-many relationship with the
Documents table. In other words, a document can have only one type and a user can have many documents.
Now let’s take a look at these classes and the code behind to see the relationship. Let’s start with the Document
class as shown in Listing 9-1.
Listing 9-1. Document.java
package com.apress.isf.java.model;
import java.util.Date;
public class Document {
private String documentId;
private String name;
private Type type;
private String location;
private String description;
private Date created;
private Date modified;
public String getDocumentId() {
return documentId;
}
public void setDocumentId(String documentId) {
this.documentId = documentId;
}
public String getName() {
return name;
}
