In the middle of the 1990s, Bell Labs researchers created DSL, a WAN communication method. It utilizes the PSTN and immediately competes with T-1 and broadband cable services (which combines voice and data onto an analog phone line).
What is DSL?A group of technologies known as digital subscriber lines (DSL; formerly known as digital subscriber loop) is used to carry digital data over telephone lines.
The most widely used DSL technology for Internet access is known as asymmetric digital subscriber line, or ADSL, in the telecommunications industry.
Bell Labs researchers developed DSL, a WAN connection technique, in the middle of the 1990s.
It competes directly with T-1 and broadband cable services and uses the PSTN (which combines voice and data onto an analog phone line).
Since DSL uses higher frequency bands for data, it is possible to transmit both wired and wireless services over the same phone line on the client's property.
Therefore, in the middle of the 1990s, Bell Labs researchers created DSL, a WAN communication method. It utilizes the PSTN and immediately competes with T-1 and broadband cable services (which combines voice and data onto an analog phone line).

The first blank refers to "White-box testing", the second blank refers to "Black-box testing", the third blank refers to "Functional testing", the fourth blank refers to "Test automation framework", and the fifth blank refers to "Regression testing".
Code-based testing involves analyzing the code structure and the logic of the program to determine the most effective test cases. This method can include structural, functional, and white-box testing techniques. On the other hand, data-based testing is concerned with examining the data that is flowing in and out of the system, as well as examining logs to ensure that the data is being processed as expected. Input-output testing, also known as black-box testing, checks that the system behaves correctly with various inputs, without regard to the code. A framework for automating tests is a software tool that provides a pre-designed structure for writing, executing, and maintaining test cases. Regression testing involves rerunning test cases that have been run before to ensure that changes made to the system do not break previously working functionality.

I am providing you the high level design for my project. I want to make a context diagram , activity diagram and sequence diagram based on the high level design for my project. HIGH LEVEL DESIGN:The high-level design of the Cody platform will be presented through multiple viewpoints, including conceptual or logical, process, module, and security. The conceptual or logical view will show the functional elements of the system, such as the server-side and client-side components, and the APIs connecting them. The process view will show the runtime behavior of the system, such as the execution of user code and the communication between the server and client components. The module view will show the organization of the code into packages or directories, and the security view will focus on the components responsible for ensuring the security of the system and user data.
The diagrams to represent what the context diagram, activity diagram, and sequence diagram for the Cody platform could look like is given below.
How to depict rye diagramA context diagram provides a high-level view of the system and its environment, showing how the system interacts with external entities. In this case, the context diagram for the Cody platform could look something like this:
+------------+ +-----------------+ +---------------+
| | <--> | | <--> | |
| User | | Cody Server | | Third-Party |

Produce a listing: custName, No_of_orders, avg_order_amt, where the middle column is the total number of orders for the customer and the last column is the average order amount for that customer. HINT: Use column aliases to get the column headings listed above to display for the output. Also, this requires two aggregate functions to be listed in the SELECT clause.
I mean I want my query to select each customer, find how many order each customer make, and average the order amount each customer has.
2) Find the customerID, customer name, orderID and total value of the order for those orders that have not been shipped. HINT: Orders that have not been shipped have a NULL value for the shipDate.
Can you help me to find the error or missing command? Here is my tables and code:
SQL Tables
1.
Select c.cname as custName, sum(o.orderID) as No_of_orders, avg(i.price) as avg_order_amt
From Customer c, Item i
Join Order_ o
On o.customerID = c.customerID and o.itemID = i.itemID;
2.
Select c.customerID, c.cname, o.orderID
From Order_ o
Join Customer c
On c.customerID = o.customerID
Where o.orderDate = Null;
The error in the first query is joining the Order_ table without a join condition, and the error in the second query is using = Null to filter for null values instead of using IS NULL.
1. To select each customer, find how many orders each customer makes, and average the order amount for each customer, you can use the following SQL query:
SELECT c.custName, COUNT(o.orderID) AS No_of_orders, AVG(i.orderAmount) AS avg_order_amt
FROM Customer c
JOIN Orders o ON c.customerID = o.customerID
JOIN OrderItems i ON o.orderID = i.orderID
GROUP BY c.custName;
This query joins the Customer, Orders, and OrderItems tables and uses the COUNT and AVG aggregate functions to calculate the total number of orders and the average order amount for each customer. The GROUP BY clause groups the results by customer name.
2. To find the customerID, customer name, orderID, and total value of the order for those orders that have not been shipped, you can use the following SQL query:
SELECT c.customerID, c.cname, o.orderID, SUM(i.price * i.quantity) AS total_value
FROM Customer c
JOIN Orders o ON c.customerID = o.customerID
JOIN OrderItems i ON o.orderID = i.orderID
WHERE o.shipDate IS NULL
GROUP BY c.customerID, c.cname, o.orderID;
This query joins the Customer, Orders, and OrderItems tables and uses the SUM aggregate function to calculate the total value of each order. The WHERE clause filters out orders that have a non-null value for the shipDate column. The GROUP BY clause groups the results by customer ID, customer name, and order ID.

The following statement(s) regarding Utility Functions is/are true:
Utility Functions are usually a function of wages.
Utility increases at a decreasing rate.
The Utility Function chosen does not matter. They will all yield the same result.
Group of answer choices
I
II
III
I and III
All are true
None are true
The correct statement regarding Utility Functions is: II. Utility increases at a decreasing rate.
This statement is true because the concept of utility refers to the amount of satisfaction or happiness that a person derives from consuming a good or service, and it is generally assumed that the more a person has of a good or service, the less additional utility they will get from each additional unit. This is known as the principle of diminishing marginal utility, which implies that utility increases at a decreasing rate.
Statements I and III are incorrect because:
I. Utility Functions are usually a function of wages: While it is true that utility functions can be used to model consumer behavior, they are not necessarily a function of wages, and can be a function of other variables such as prices, income, or other attributes of the goods or services being consumed.
III. The Utility Function chosen does not matter. They will all yield the same result: This statement is false because the specific form of the utility function does matter, as it affects the shape of the utility curve and the resulting optimal consumption bundle. Different utility functions can lead to different results, even if they represent the same underlying preferences.

which of the following mechanisms is considered a specialized variation of the cloud usage monitor mechanism
Virtualization monitor is the appropriate response. A specialised version of the usage monitor method is the virtualization monitor.
In computing, the process of producing a virtual counterpart of something at the same abstraction level includes virtualizing computer hardware platforms, storage systems, and network resources. The concept of virtualization first emerged in the 1960s as a way of rationally allocating mainframe computer system resources to various applications. IBM CP/CMS is a pioneering and effective case in point. Each user had a virtual standalone System/360 machine thanks to the control programme CP. The term's definition has expanded since that time. The development of an operating system-equipped virtual machine that mimics a real computer is known as hardware virtualization or platform virtualization.
