Answer:c)Clean redundant customer data
Explanation:Data cleansing/cleaning is the activity for the elimination of the data which is not required for further use, corrupt, unnecessary etc by detecting it. The data that is being cleared is categorized by levels like irrelevant data, incorrect data, inaccurate data, redundant data etc.
The data is eliminated by the method of correcting , modifying, reducing unnecessary parts,deleting, etc.Thus, the correct option is option(C).
Answer:
1. FDD is a process and Analysts can use a FDD to create and use business functions and processes. It Requirements models are used when gathering requirements for a new system.
2. BPM is used on an ongoing basis for business process improvement. It is meant to improve order, insight and efficiency of the collective workflows that make up any given business process. BPM is meant to reduce any chaos within those collective workflows that make up a process and eliminate ad hoc workflow management. BPM means Business Process Management.
3. DFDs stands for Data Flow Diagram which will help software developers and designers to understand how they can take their next step to fit into the overall business process. DFDs paly key role for a successful requirements modeling.
4. UML can be used for modeling a system independent of a platform language. UML is a graphical language for visualizing, specifying, constructing, and documenting information about software-intensive systems. UML gives a standard way to write a system model, covering conceptual ideas.
Explanation:
Functional decomposition diagram (FDD) is used to identify functions and define their structure. It is a technique to decompose the complex problem into manageable pieces or individual elements to develop the application or product.
DFDs: It contains a process (shape) that represents the system to model, in this case, the "Food Ordering System". It also shows the participants who will interact with the system, called the external entities. In this example, Supplier, Kitchen, Manager and Customer are the entities who will interact with the system.
Unified Modeling Language (UML): Edraw UML Diagram is the application of choice for many software engineers and designers. The software is fully compatible with 64 and 32-bit Windows platforms from Windows XP to Windows 10.
Integrating 3D graphics to provide a live, direct, or indirect view of a physical real-world
Answer:
fav_number=26
guess=0
while 0==0:
try:
guess=int(input('Enter your guess: '))
except:
print ('You have entered an invalid value.')
else:
if guess == fav_number:
break
elif guess>fav_number:
print ('Try a smaller number.')
elif guess<fav_number:
print ('Try a larger number')
Explanation:
define a variable fav_number and set it to number. write an infinite while loop to read input from user. In try block get input from user, if user enters invalid input code in except block will be executed. For valid input
- check if its greater than favorite number, if yes print try smaller number.
- check if its smaller than favorite number, if yes print try larger number.
- check if its equal to favorite number, break loop and exit
