Chapter 4, Problem 17RQ
Explanation of Solution
Cardinality:
Connecting lines among the entities will illustrate the relationships of entities in the ER diagram.
- “Cardinality” states that how many occurrences of an entity relate to one occurrence of other entity.
Crow’s Foot symbols and its cardinality:
The following table illustrates the different connectivity and participation combinations which are maintained by the Crow’s Foot notation:
| Notation | Cardinality | Description |
| (0,N) | Zero or more instances | |
| (1,N) | One or more instances | |
| (1,1) | One instance | |
| (0,1) | Zero or one instance |
Cardinalities for given ERD:
The following figure illustrates the cardinalities for each relationship in given ER diagram:

CIT244 Program Project 3 Assignment
As with any assigned program, do not wait until the last minute to start. Start early in the week
the program is due so you can ask questions if you get stuck
Node.js and Express and Nunjucks Templates
We have gotten to the good stuff. There is a program similar to this assignment
given as the last example in the lecture notes for the week that discusses node
static files. This program will take more time that previous assignments.
There are several examples you should study first, particularly the pizza order
example program available in the examples programs folder for the week
discussing static files. You should study and run the pizza order program before
trying this program.
The pseudo-company is called Sun or Fun, which offers cheap flights from
Louisville to either Miami or Vegas.
Here's a video of how it should work.
NOTE: You will hear or see references to Handlebars in this video. We used to
use Handlebars, but it will be Nunjucks that we…

Then it would mean that all problems in NP can also be solved in cubic time. If a problem can be solved using Dynamic Programming, then it is not NP-complete. Suppose X and Y are two NP-complete problems. Then, there must be a polynomial-time reduction from X to Y and also one from Y to X.arrow_forwardMaximum Independent Set problem is known to be NP-Complete.
