Jason works as a financial investment advisor. He collects financial data from clients, processes the data online to calculate t

Ghella [55]

Answer:

The answer to this question is given below in the explanation section.

Explanation:

The correct answer to this question is an online decision support system. Because the decision support systems process the data, evaluate and predict the decision, and helps the decision-makers, and offer real-time information immediately in making the decision in an organization. So the correct answer to this question is the decision supports system.

Why other options are not correct

Because the transaction processing system can only process the transaction and have not the capability to make the decision for the future. Office support processing system support office work, while the batch processing system process the task into the batch without user involvement. however, online executive processing does not make decisions and offer timely information to decision-makers in an organization.

Compare the elements of the basic Software Development Life Cycle with 2 other models. How are they similar? How are they differ

Artemon [7]

Answer:

Explanation:

One of the basic notions of the software development process is SDLC models which stands for Software Development Life Cycle models. SDLC – is a continuous process, which starts from the moment, when it’s made a decision to launch the project, and it ends at the moment of its full remove from the exploitation. There is no one single SDLC model. They are divided into main groups, each with its features and weaknesses. The most used, popular and important SDLC models are given below:

1. Waterfall model

2. Iterative model

3. Spiral model

4. V-shaped model

5. Agile model

Stage 1. Planning and requirement analysis

Each software development life cycle model starts with the analysis, in which the stakeholders of the process discuss the requirements for the final product.

Stage 2. Designing project architecture

At the second phase of the software development life cycle, the developers are actually designing the architecture. All the different technical questions that may appear on this stage are discussed by all the stakeholders, including the customer.

Stage 3. Development and programming

After the requirements approved, the process goes to the next stage – actual development. Programmers start here with the source code writing while keeping in mind previously defined requirements. The programming by itself assumes four stages

• Algorithm development

• Source code writing

• Compilation

• Testing and debugging

Stage 4. Testing

The testing phase includes the debugging process. All the code flaws missed during the development are detected here, documented, and passed back to the developers to fix.

Stage 5. Deployment

When the program is finalized and has no critical issues – it is time to launch it for the end users.

SDLC MODELS

Waterfall – is a cascade SDLC model, in which development process looks like the flow, moving step by step through the phases of analysis, projecting, realization, testing, implementation, and support. This SDLC model includes gradual execution of every stage completely. This process is strictly documented and predefined with features expected to every phase of this software development life cycle model.

ADVANTAGES

Simple to use and understand

DISADVANTAGES

The software is ready only after the last stage is over

ADVANTAGES

Management simplicity thanks to its rigidity: every phase has a defined result and process review

DISADVANTAGES

High risks and uncertainty

Iterative SDLC Model

The Iterative SDLC model does not need the full list of requirements before the project starts. The development process may start with the requirements to the functional part, which can be expanded later.

ADVANTAGES

Some functions can be quickly be developed at the beginning of the development lifecycle

DISADVANTAGES

Iterative model requires more resources than the waterfall model

The paralleled development can be applied Constant management is required

Spiral SDLC Model

Spiral model – is SDLC model, which combines architecture and prototyping by stages. It is a combination of the Iterative and Waterfall SDLC models with the significant accent on the risk analysis.

A company wants to inform a select list of it's regular customers about a flash sale. Which type of platform will it use to send

blondinia [14]

<h2>Answer :</h2>

In case of Flash Sale, usually company uses Instant messages or SMS. As there are chances customer in most of the cases don’t have access to their emails due to internet unavailability.

There are three seating categories at a stadium. Class A seats cost $20, Class B seats cost $15, and Class C seats cost $10. Wri

Westkost [7]

Answer:

Following are the program to this question:

def calculate_income(num,seat):#defining method calculate_income

if seat=="A": #defining condition for seat a

return num * 20 #return value

if seat=="B": #defining condition for seat b

return num * 15 #return value

if seat=="C": #defining condition for seat c

return num * 10 #return value

def show_income(a,b,c): #defining method show_Income

sum=a+b+c # add total seats income

print("Income for A class seats: $",a) #print value

print("Income for B class seats: $",b) #print value

print("Income for C class seats: $",c) #print value

print("Total Income: $",sum) #print value

def main(): # defining main method

a=int(input("Enter class A seats: ")) #input seats a value

b=int(input("Enter class B seats: ")) #input seats b value

c=int(input("Enter class C seats: ")) #input seats c value

a_income=calculate_income(a,"A") #call method for seat a

b_income=calculate_income(b,"B") #call method for seat b

c_income=calculate_income(c,"C") #call method for seat c

show_income(a_income,b_income,c_income) # call method show_income for print all seat value

main()

Output:

Enter class A seats: 2

Enter class B seats: 3

Enter class C seats: 2

Income for A class seats: $ 40

Income for B class seats: $ 45

Income for C class seats: $ 20

Total Income: $ 105

Explanation:

The description of the above program can be described as follows:

In the above python program, three methods "calculate_income, show_income, and the main method" were defined.
The method "calculate_income" accepts two-variable "num and seat" as the parameter, inside the method a three if block is used, that calculate all types of seat class rate and returns its value.
In the "show_income", we add all the seat value in the sum variable and use the print method, that prints all seat cost, and total cost.
In the main method, we input all seat value from user input and pass into the calculate_income method and collect all the return value, after calculating calculate_income we pass its return value into the show_income method, that prints all value.
