Answer:

1. get the absolute path to the file

2. load the file as a table (dataframe in python)

3. to insert a row;

  • create a dataframe of the same field type
  • concatenate the new dataframe horizontally with the same dataframe

4. to delete a row, select and drop the row where the 'Number' field matches a value.

5. to update the values in row, use the number field as a key to replace the existing values.

6. print of save to a variable the rows where the number field matches a given value.

Explanation:

Follow the report template to create a report for the algorithm.

The algorithm gets the absolute path to the file and loads the file as a tabular file from there the data can be queried without accessing the main file. The insert algorithm creates a new dataframe and appends it to the main dataframe.

The delete, update and retrieve all use the same subalgorithm, getting the rows with the number field as the key value.

Dmitriy789 [7]

Answer:

The full program is:

<em>num1 = int(input()) </em>

<em>num2 = int(input()) </em>

<em>print(num1 + num2)</em>

Explanation:

Given

<em>num1 = int(input()) </em>

<em>num2 = ?</em>

<em>print(num1 + ?)</em>

<em />

Required

Replace ? with the right codes

Line 1: The syntax is correct

Line 2: The ? should be replaced with an integer input function to get input for num2.

So, the second line would be: <em>num2 = int(input()) </em>

Line 3: The ? should be replaced with num2 in order to calculate and print the required sum.

So, the third line would be: <em>print(num1 + num2)</em>

A leading pharmaceutical company is launching a major transformation of its entire Cloud operations in order to more quickly and
klasskru [66]

This is a great move for the Pharmaceutical company for a number of reasons.

  • The first and perhaps most important advantage is to the company is that costs relating to Information and Technology (IT) Infrastructure will be reduced to the barest minimum. As a start-up, it is important to keep costs as low as possible. Costs are kept low because the organization will not need to pay the added energy and personnel-related costs of maintaining an elaborate IT infrastructure.

  • The advantage of scalability. Scalability in this sense simply means the ability to take on additional workload or adjust to market demand. As the company grows and attracts more clients, it would need to expand beyond the capacity that it had at the onset. Opting for Cloud as a Service (CaaS) gives them this advantage.

  • Another way CaaS can help the client is that they enjoy the advantage of Business Continuity. Business Continuity is the ability to remain in business regardless of disruptions to the business itself at one location. This is because CaaS providers are structured in such a way that they are able to keep their subscribers in operation regardless of any disasters.

Other advantages to this client are:

  1. Ease and access of automatic updates to the system;
  2. Ease of collaboration between internal and external users of the same system.
