Differentiate between frames and panels.

 What is a Frame?

The frame is a component that works as the main top-level window of the GUI application. It is created using the Frame class. For any GUI application, the first step is to create a frame. There are two methods to create a frame: by extending the Frame class or by creating an object of Frame class.

The frame is a resizable and movable window. It has the title bar. The default visibility of a Frame is hidden. The programmer has to make it visible by using the set Visible method and providing the value “true” to it.

What is a Panel?

The panel actually serves as a general-purpose container. It is where more complex, or bigger operations, are usually put. It is opaque by default, but you can change its background color. You can also customize its components using the Layout Managers.



Notable Differences Between Frame And Panel

1. Panel requires a Frame to display it. A frame can consist of a panel or a set of panels.

2. A-frame is a top-level window. It has a title bar, menu bar, borders, and resizing corners.

3. A Panel is a subclass of Container while Frame is a subclass of Window.

4. Frame is used for standalone desktop applications.

5. Panel is a component object containing another component object.

6. Panel represents an area used for more complex operations or applications.

Suppose that a data warehouse consists of the three dimensions time, doctor, and patient, and the two measures count and charge, where a charge is the fee that a doctor charges a patient for a visit. a) Draw a schema diagram for the above data warehouse using one of the schemas. [star, snowflake, fact constellation] b) Starting with the base cuboid [day, doctor, patient], what specific OLAP operations should be performed in order to list the total fee collected by each doctor in 2004? c) To obtain the same list, write an SQL query assuming the data are stored in a relational database with the schema fee (day, month, year, doctor, hospital, patient, count, charge)
