Answer: Option(d) is correct
Explanation:
Data warehouse is the storage that holds collected information and data for making acknowledged decision through analyzing the data. Data present in data warehouse is as per subject which contains history and sources of data for understanding and perceiving it.
- Other options are incorrect because data is not coded in various forms,retrieved for certain period of time, real-time update and arrangement in hierarchical form.
- Thus, the correct option is option(d).
Answer:
Explanation:
temporal locality can be defined as: when a particular memory is referenced or accessed several times within a specific period of time. In the question, i think the variable that exhibit temporal locality are I, J and 0(all the variable). This is because the variable J and 0 are accessed several times within the loop. I would not have been part of it, but in the A[I][J]=B[I][0]+A[J][I], the variable "I" is also accessed in the addition. this is why it is part of the temporal locality.
Answer:
b. myString[:-5]
d. myString[-15:-5]
Explanation:
I believe you have a typo in d. It must be d. myString[-15:-5]
Slicing can be done:
myString[starting_index, stopping_index, step] (step is optional). If you do not specify the starting index, it will start from the 0 as in b. If you write a range that is not in the range, as in d, Python will replace it with either 0 or length of the string (In this case, it is replaced with 0 because the starting index must be smaller than stopping index)
a. myString[5] → This will give you the sixth character
b. myString[:-5] → This will give you the first five characters
c. myString[0:6] → This will give you the first six characters
d. myString-15:-5] → This will give you the first five characters
e. myString[0:10:2] → This will give you the first, third, fifth, seventh, and ninth characters
Sean is using FUNCTION POINT (d) method for forecasting the time and cost of developing a customized software program by looking at the number of inputs, outputs, inquiries, files, and interfaces.
Explanation:
- The function point is a "unit of measurement" to express the amount of business functionality an information system (as a product) provides to a user.
- The outcome of a function point count provides the metric 'unit of software delivered' and can be used to assist in the management and control of software development, customisation or major enhancements from early project planning phases, through to the ongoing support of the application.
