disadvantage of monolithic programming
Answer:
=Tight coupling between components, as everything is in one application.
=Less reusability.
=Large code base; tough for developers and QA to understand the code and business knowledge.
=Less Scalable.
=Does not follow SRP (Single Responsibility Principle)
=More deployment and restart times.

Select the scenario that describes a top-down approach to data warehouse design.
Cathy’s Cards and Gifts, which has three stores, creates data marts for its sales, marketing, and delivery departments to study the possibility of establishing a new store.
Crawford's Fabrics, which wants to expand its operations, combines data from the purchasing and sales departments into a central database, to be divided into new data marts as needed.
Cynthia’s Florals, which is dealing with debt, creates new data marts for the service, delivery, and sales departments to develop a strategy to stay in business.
Connor’s Meat Market, which just opened, creates data marts to track the sale of each of the following meats: beef, pork, lamb, and fish.
Answer:
Crawford's Fabrics, which wants to expand its operations, combines data from the purchasing and sales departments into a central database, to be divided into new data marts as needed.
The scenario defines a top-down approach to data warehouse design as "Crawford's Fabrics, which wants to expand its operations, combines data from the purchasing and sales departments into a central database, to be divided into new data marts as needed".
What is a top-down approach to data warehouse design?In the "Top-Down" method system, a data warehouse exists defined as a subject-oriented, time-variant, non-volatile, and integrated data storage for the entire business data from various sources exist validated, reformatted, and saved in a normalized (up to 3NF) database as the data warehouse.
Therefore, the correct answer is option b) Crawford's Fabrics, which wants to expand its operations, combines data from the purchasing and sales departments into a central database, to be divided into new data marts as needed.

Explain how mobile phone production could be more sustainable
Answer:
Sustainable design - the key features for sustainable phones are: use of sustainable and recycled materials, the use of less energy and efficient charging, durability, and last but not least they should be easy and inexpensive to repair.
Answer:
One of the best ways to change this is to voice your concern to cell phone manufacturers for more sustainable products. Request smartphones that are made with fewer hazardous chemicals, manufactured in plants powered by renewable energy, and that contain recycled materials.

Answer:
computer is defined as a electronic machine which gives us meaningful result as fast as possible
Answer:
As known a computer can be defined as the use of computers to store, retrieve, transmit and manipulate data or information.
Write a program that uses the function strcmp() to compare two strings input by the user. The program should state whether the first string is less than, equal to, or greater than the second string7.

Polymorphism with Stores - PYTHON
The goal of this program is to create classes that represent to a certain degree different types of stores in real life and the information tracked and services provided by these stores. In order to accomplish this the following required classes have to be created:
I. Create a file called store.py which contains an abstract class called Store which is made up of the following:
Attributes/Properties
o Store name
o Store address
Store availability/status (open or closed)
o Sales tax percentage Functions/Functionality
o Constructor which provides the ability to pass and set the values for the various attributes
Getter and setters for all the attributes mentioned above is_store_open should return True if the store is open and False if the store is closed
Abstract function called: calculate_total_sales_tax
o Abstract function called calculate_total_sales
II. Create a file called restaurant.py which contains a class called Restaurant which is type of Store. It should possess all the attributes and functions present in the Store class without having to re-implement those in the Restaurant class.
The Restaurant class is made up of the following:
Attributes/Properties
o Total number of people served Max occupancy
o Current occupancy o Price per person Functions/Functionality
o Constructor which provides the ability to pass and set the values for the various attributes
seat_patrons should do the following: Take the number of people to be seated as input
Update the values of the appropriate attributes
If number of people to be seated does not exceed or equals the max occupancy
Print "Welcome to [replace with name of restaurant]"
• Return True If number of people to be seated exceeds the max occupancy
Print "We are at capacity, we appreciate your patience"
Return False
serve_patrons which should do the following:
Take the number of people to serve as input
Update the values of the appropriate attributes
Return the number of people being served currently
o checkout_patrons (this is when the patrons are ready to leave the restaurant) which should do the following:
Take the number of people leaving as input
Update the values of the appropriate attributes
Return the current occupancy of the restaurant
o Create a getter and setter for the attribute: Price per person
III. Create a file called grocery_store.py which contains a class called GroceryStore which is type of Store.
It should possess all the attributes and functions present in the Store class without having to re-implement those in the GroceryStore class.
The GroceryStore class is made up of the following:
Attributes/Properties
o Total revenue
Grocery store type (independent or chain)
Functions/Functionality
o Constructor which provides the ability to pass and set the values for the various attributes
sell_item which should do the following:
Takes the quantity and price of an item as input
Update the values of the appropriate attributes
Return the total revenue of the grocery store
o Create a getter and setter for the attribute: Grocery Store type
IV. Create a file called shopping.py which will make use of the above mentioned Restaurant and GroceryStore classes and call their various functions to simulate the actions which take place in real life restaurants and grocery stores in order to test your code.
Reminder: Do not forget to implement the two abstract functions specified in the Store class within each of the classes mentioned above
Answer:
. Create a file called store.py which contains an abstract class called Store which is made up of the following:
Attributes/Properties
o Store name
o Store address
Store availability/status (open or closed)
o Sales tax percentage Functions/Functionality
o Constructor which provides the ability to pass and set the values for the various attributes
Getter and setters for all the attributes mentioned above is_store_open should return True if the store is open and False if the store is closed
Abstract function called: calculate_total_sales_tax
o Abstract function called calculate_total_sales
Polymorphism is used in Python for a variety of purposes, most notably Duck Typing, Operator and Method overloading, and Method overriding, just like it is in other programming languages like Java and C++.
What role of Polymorphism is used in different program?The + operator is used to execute arithmetic addition operations on integer data types. As a result, the procedure above produces 3. The + operator is also used to execute concatenation for string data types. The output of the aforementioned application is Python Programming.
The opposite of uniformity, polymorphism, is defined as having “various forms.” Overloading and overriding are two different approaches to implement this polymorphism.
Therefore,`Three types of polymorphism exist in object-oriented programming languages: subtype polymorphism, parametric polymorphism, and ad-hoc polymorphism.
