Optional attributes and relationships become columns that allow for nullable values.
This means that a row in the database table can have a null value for that particular attribute or relationship. Nullable columns are important because not all entities will have values for all attributes or relationships. For example, a customer entity may not have a value for the "fax number" attribute, or a product entity may not have a value for the "supplier" relationship. Without nullable columns, these entities would not be able to be properly represented in the database. Nullable columns also allow for flexibility in data entry and querying, as they allow for the possibility of missing or unknown data.

* Since it is language independent, it can be translated to any computer language code.
* It allows designer to express logic in plain natural language.

PLS HELP ASAP suppose you want to find pages that contain the word German but not the word shepherd. which search would achieve this?
German OR shepherd
German- shepherd
"GERMAN shepherd"
"German"+"shepherd"
Answer: German- shepherd
Explanation:
If I want to find pages that contain the word German but not the word shepherd, the search would achieve this would be German- shepherd.
It should be noted that other options such as German OR shepherd, "GERMAN shepherd" and "German"+"shepherd" all mean that pages containing the words German and also shepherd will be found.
The (-) sign simply means that not. Therefore, the correct option is German - shepherd which means German but not shepherd.

Find the cost of 2m 20cm at 25p per metre
Answer: 55 meters.
Explanation:
First convert the 20 cm to meters so the entire number is in meters.
1 meter = 100 cm
20 in cm is:
= 20/100
= 0.2 meters.
2.2 meters.
One meter costs 25p so 2.2 meters will cost:
= 2.2 * 25
= 55 meters

I need help writing the algorithm I know how to do the flow chart for the first one but I’m not sure if the second question is a for loop
Answer:
The algorithm is as follows:
(a) Sales and commission
1. Start
2. Input Sales
3. Commission = 0.30 * Sales
3. If sales >= 4000.00 then
3.1 Commission = 0.60 * Sales
4. End If
5. Print Commission
6. Stop
(b) Amount of Rainfall
1. Start
2. Days = 1
3. Total = 0.0
4. While Days <= 31
4.1. Input Rainfall
4.2. Total = Total + Rainfall
4.3. Days = Days + 1
4.4. End If
5. Print Total
6. Stop
See attachment for flowchart
Explanation:
(a) Sales and commission
This begins the algorithm
1. Start
This gets sales from the user
2. Input Sales
This calculates the commission based on 30% (i.e. for sales < 4000)
3. Commission = 0.30 * Sales
This checks if sales is greater than or equal to 4000
3. If sales >= 4000.00 then
This calculates the commission as 60% of Sales
3.1 Commission = 0.60 * Sales
This ends the if condition
4. End If
This prints the calculated commission
5. Print Commission
This ends the algorithm
6. Stop
(b) Amount of Rainfall
This begins the algorithm
1. Start
This initializes the number of days to 1
2. Days = 1
This initializes total rainfall to 0
3. Total = 0.0
The following while loop is repeated until day 31st
4. While Days <= 31
This gets input for Rainfall from the user
4.1. Input Rainfall
This calculates the total rainfall
4.2. Total = Total + Rainfall
This increments the number of days
4.3. Days = Days + 1
This ends the if statement
4.4. End If
This prints the total rainfall
5. Print Total
This ends the algorithm

Answer:
. ¿Dónde emergieron los Bancos Centrales?
El primer banco central fue creado por el Parlamento Sueco en 1668, siendo su principal acreedor la Corona Sueca. Esto generó inflación y crisis financieras. Después de un siglo, en 1779, la ley fue modificada, obligando al Banco a que la masa monetaria fuese respaldada por oro en una proporción fija. Sin embargo, comenzó la guerra con Rusia y se regresó a su origen violando el precepto de estabilidad que confería ese patrón oro.
2. ¿En qué siglo los Bancos Centrales se potenciaron?
La historia de la banca central se remonta al menos al siglo XVII, con la fundación de la primera institución reconocida como un banco central, el Banco de Suecia.
3. ¿El Banco de Suecia en qué siglo fue fundado?

A principios del siglo XIX, Estados Unidos creó el Banco de los Estados Unidos (1791-1811) y luego un segundo Banco de los Estados Unidos (1816-1836) tras el cierre del primero. Ambos bancos se establecieron siguiendo el modelo del Banco de Inglaterra. Pero a diferencia de los británicos, los estadounidenses tuvieron una desconfianza profunda de cualquier concentración de poder financiero en general, y de los bancos centrales, en particular.

Answer:
Coke has experimented with different formulations of its popular Coca Cola product, including the failed New Coke iteration. The aim is to achieve the best tasting product that customers like.
A company that is operating a factory or assembly line may experiment with different methods of arranging the assembly line or with different production methods. Each time the production process is changed, this is a different iteration. Each time the order of operations and procedures are changed, this is a different iteration. The goal is to achieve the fastest, best and most optimal method of creating a product.
A musician may start with one version of a song and refine it, making changes to a note here and there or changing the tempo and speed. Many different iterations of a song may be created this way until the optimal finished product has been created that sounds and works the best.
A cook may experiment with a recipe, tweaking the ingredients or changing different steps of the process slightly until the food tastes as good as it possibly can.
Microsoft has released multiple versions of the Windows operating system to add functionality for users and to correct bugs. Each different version is a different iteration of its operating system and the goal is for the next iteration to be better than the last.
