Sure, here is an example of how to write a Java interface that packages database data:
```
public interface DatabasePackage {
public void packageData(String tableName);
}
```
You can then implement this interface in a class that retrieves data from a database and packages it in some way. For example:
```
public class MyPackage implements DatabasePackage {
private Connection connection;
public MyPackage(Connection connection) {
this.connection = connection;
}
public void packageData(String tableName) {
// Get data from database and package it
// ...
}
}
```
