Answer:
Case-based reasoning.
Explanation:
A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to create, store, modify, retrieve and manage data or informations in a database. Generally, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.
A data dictionary can be defined as a centralized collection of information on a specific data such as attributes, names, fields and definitions that are being used in a computer database system.
In a data dictionary, data elements are combined into records, which are meaningful combinations of data elements that are included in data flows or retained in data stores.
This ultimately implies that, a data dictionary found in a computer database system typically contains the records about all the data elements (objects) such as data relationships with other elements, ownership, type, size, primary keys etc. This records are stored and communicated to other data when required or needed.
Basically, when a database management system (DBMS) receives data update requests from application programs, it simply instructs the operating system installed on a server to provide the requested data or informations.
Case-based reasoning is a problem-solving technique where each problem in a database is stored with a description and keywords that identify it. It is typically based on cognitive science and artificial intelligence.
Answer:
The answer is letter C. The letter C is the true statement.
Explanation:
The true statement is The point-of-sale terminal cannot connect directly to the Internet.
I am not too familiar with the Python language, but the algorithm would be something like this:
1. create a variable for the sums of the number
2. read in how many numbers the user wants to enter (let's call it N)
and then create a for loop:
for N times
read in the next number
increase the sum variable by that number
Hopefully this helps!
Answer:
See explaination
Explanation:
#include <iostream>
using namespace std;
int main()
{
double h, w;
int s, a, b;
cout<<"height in feet: ";
cin>>h;
cout<<"width in feet: " ;
cin>>w;
cout<<"tile size in inches:";
cin>>s;
int height = h*12;
if(height%s==0)
a = height/s;
else
a = height/s + 1;
int width = w*12;
if(width%s==0)
b = width/s;
else
b = width/s + 1;
cout<<"Number of tiles: "<<a*b;
}
Answer: I think a
