Chapter 23, Problem 7PE
Program Plan Intro
Lazy data replication strategy:
- This process is also known as asynchronous replication, involving multiple steps of copying updates of the transaction.
- Both master and group replication are asynchronous.
- In the case of asynchronous updates where the user pays for data inconsistency, the inconsistency may be specified and consistent data may be provided.
- This lazy group replication allows updating any local data. This shall also extend to all other nodes until the transaction has been committed.

Based on the given problem, create an algorithm and a block diagram, and write the program code:
Function: y=xsinx
Interval: [0,π]
Requirements:
Create a graph of the function.
Show the coordinates (x and y).
Choose your own scale and show it in the block diagram.
Create a block diagram based on the algorithm.
Write the program code in Python.
Requirements:
Each step in the block diagram must be clearly shown.
The graph of the function must be drawn and saved (in PNG format).
Write the code in a modular way (functions and the main part should be separate).
Please explain and describe the results in detail.

The table includes columns about customer location such as city, state, and country. You want to retrieve the first 3 letters of each country name. You decide to use the SUBSTR function to retrieve the first 3 letters of each country name, and use the AS command to store the result in a new column called new_country. You write the SQL query below. Add a statement to your SQL query that will retrieve the first 3 letters of each country name and store the result in a new column as new_country.arrow_forwardWe are considering the RSA encryption scheme. The involved numbers are small, so the communication is insecure. Alice's public key (n,public_key) is (247,7). A code breaker manages to factories 247 = 13 x 19 Determine Alice's secret key. To solve the problem, you need not use the extended Euclid algorithm, but you may assume that her private key is one of the following numbers 31,35,55,59,77,89.arrow_forward
