Program Plan Intro
Transaction Processing System (TPS):
- TPS handles the everyday accounting needs of an organization.
- TPS is also referred as data processing
system or operational system. - To know the stock of a particular item, often the TPS is connected with the control systems of production and inventory.
- TPS is also referred as data processing
Program Plan Intro
Online Transaction Processing (OLTP):
- OLTP is the program that is used for supporting transaction oriented applications over the internet.
- It is helps in retail sales, Customer Relationship Management (CRM), financial transactions and order entries.
- It includes three steps. They are:
- Collecting the input data
- Processing the data
- Updating the existing data
- The performance of OLTP includes clusters, discrete transactions, rollback segments,
database tuning, buffer cache size and many others.

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.…

Our problem is a 2x2 binary sudoku, which in our case has two simple rules: •No column may contain the same value twice •No row may contain the same value twice If we assign each square in our sudoku to a variable like so: 1 V V₁ V3 V2 we want our circuit to output a solution to this sudoku. Note that, while this approach of using Grover's algorithm to solve this problem is not practical (you can probably find the solution in your head!), the purpose of this example is to demonstrate the conversion of classical decision problems into oracles for Grover's algorithm.
