Answer:
Data acquisition should follow a detailed collection plan that is set in advance.
Explanation:
The process of collection of data over computer with the help of electronic sensors is called data acquisition. The can be related to voltage, current, temperature etc.
For example
Data collection with the help of sensors to monitor weather conditions is an example of data acquisition. In this process data has been gathered on already planned format. Each column or row of data will be helpful to predict the weather condition such as, rain predictions, earthquake prediction etc.
That's why to collect this type of data, collection plan should be set in advance to gather relevant information with the help of data.
Answer:
A query in a database is a request for information stored within a database management system (DBMS), which is the software program that maintains data.
SQL(Structured Query Language ( is a standard language for storing, manipulating, and retrieving data in database.
Five types of SQL queries are:
1) Data Definition Language (DDL).
used to define and modify the structure of a database.
2) Data Manipulation Language (DML).
used to manipulate (change) the data in the database.
3) Data Control Language(DCL).
used for access control and permission management for users in the database.
4) Transaction Control Language(TCL).
used for maintaining consistency of the database and for the management of transactions made by the DML commands.
5) Data Query Language (DQL).
used for performing queries on the data within schema objects.
Answer:
function countEvens(list) {
// IMPLEMENT THIS FUNCTION!
var even = [];
for(var i = 0; i < list.length; i++){
if (list[i] % 2 == 0){
even.push(list[i]);
}
}
return console.log(even)
}
var list = [ 17, 8, 9, 5, 20 ];
var count = countEvens(list);
Explanation:
The programming language used is JavaScript.
An even variable is initialized, to hold the even variables within list.
A FOR loop loop iterates through all the elements in the list, an IF statement is used to check using the modulo division to check if the elements in the list are even.
The even elements are appended to the even list using .push() method.
Finally, the function returns the even list and outputs the list to the log using console.log(even)
.
A list is created and the function is called.
