This is about identifiers in a record referring to other records.
You can have many to one, one to one, many to many.
E.g., if you have two tables, Authors and Books, then a book record could have a reference to an author record. Since an author can write many books, this would be a many-to-one relationship.
Answer:
Explanation:
The following code is written in Python. It creates a variable that detects the current time. Then it loops through a range of numbers and chooses the last random number after 2 seconds. Finally, it prints that number to the screen. This function can be called countless times depending on the number of state lottery numbers needed.
import random
import time
start_time = time.time()
while time.time() - start_time < 2:
lottery_number = random.randint(0, 48)
print(lottery_number)
Answer:
Computer science are the disciplines that study information, computing and the applications or ecosystems where they are developed. It is a science that comes from applied mathematics and has 3 branches that are quite well known. On the one hand we have software engineering, secondly theory as such (primary study of algorithms and data, etc.) and finally the application of the amalgam of the first two, which end up resulting in disciplines such as big data, cybersecurity or computer security, machine learning, artificial intelligence, etc. However, we are talking about a very broad science with various branches of work. Technological advances that have improved the scope of education, now allow us to develop in specific skills and computer science is one of the macro careers that have benefited the most thanks to the diversity of subjects it encompasses. This is where the on-demand courses available on the edX platform come in. Computer scientists are in one of the best times for their career advancement. We invite you to be part of the technological development and information and computing technologies through online courses.

Answer:
Capture attributes as ID documents or biometric data
Explanation:
Examples of such attributes include biometrics, verified identification documents, and third-party verification procedures. To create a trusted digital ID, there are typically three steps: capturing verified attributes, verification of the documents, and digitization of the ID.
