Explanation of the concept of Data and Process Modeling and the tools for it.
Explanation of Solution
Data and Process Modeling is a way of developing a graphical model that shows how a system converts data into valuable information. The result of such modeling is a logical model that provides support for business operations and ensures that user’s needs are fulfilled.
The three different graphical tools used in Data and Process Modeling are explained as below:
Data Flow Diagrams: The data flow diagrams show the movement of data through an
Object Modeling: It is another technique used for data and process modeling. Object modeling uses the concept of object-oriented analysis that describes an information system with the identification of things called as objects. In that case, an object represents an event, place, transaction or a person. The result of Object-oriented analysis forms an object model that shows an information system in the form of objects. For example, an information system for a doctor appointment in a clinic will represent doctor, patient and clinic as objects.
Entity Relationship diagram: This is another technique for Data and Process Modeling in which the models are developed with the help of a relationship in the entities. Here, the entities are considered as objects that represent an event, place, transaction or a person.

- Lab 07: Java Graphics (Bonus lab) In this lab, we'll be practicing what we learned about GUIs, and Mouse events. You will need to implement the following: ➤ A GUI with a drawing panel. We can click in this panel, and you will capture those clicks as a Point (see java.awt.Point) in a PointCollection class (you need to build this). о The points need to be represented by circles. Below the drawing panel, you will need 5 buttons: о An input button to register your mouse to the drawing panel. ○ о о A show button to paint the points in your collection on the drawing panel. A button to shift all the points to the left by 50 pixels. The x position of the points is not allowed to go below zero. Another button to shift all the points to the right 50 pixels. The x position of the points cannot go further than the You can implement this GUI in any way you choose. I suggest using the BorderLayout for a panel containing the buttons, and a GridLayout to hold the drawing panel and button panels.…arrow_forwardIf a UDP datagram is sent from host A, port P to host B, port Q, but at host B there is no process listening to port Q, then B is to send back an ICMP Port Unreachable message to A. Like all ICMP messages, this is addressed to A as a whole, not to port P on A. (a) Give an example of when an application might want to receive such ICMP messages. (b) Find out what an application has to do, on the operating system of your choice, to receive such messages. (c) Why might it not be a good idea to send such messages directly back to the originating port P on A?arrow_forwardDiscuss how business intelligence and data visualization work together to help decision-makers and data users.
