The correct answer is: Summary

<span>If you only selected fields from a single table in the first screen, then when you click the “Next >” button to continue, you will only need to provide the query with a name and then click the “Finish” button to finish creating the query. If, however, you picked data fields from two or more related tables, then when you click the “Next >” button, you will instead view a second screen which asks if you would like a “Detail” or “Summary” query. You can select the option button for the type of query that you wish to create. If you select “Summary,” then you will be able to click the “Summary Options…” button to open the “Summary Options” dialog box. In this dialog box, you can select what type of summary to perform over a selected field. Make your selections, and then click the “OK” button to return to the “Simple Query Wizard.”</span>

Define the terms candidate key and primary key. Explain the difference between a primary key and a candidate key.
Shkiper50 [21]

Explanation:

Both Primary Key and Candidate Key are the attributes that are used to access tuples from a table. These (Primary key and Candidate key) are also can be used to create a relationship between two tables.

  • A Candidate Key can be any column or a combination of columns that can qualify as a unique key in the database. Each Candidate Key can qualify as a Primary Key.
  • A Primary Key is a column or a combination of columns that uniquely identify a record. The primary key is a minimal super key, so there is one and only one primary key in any relationship.

<em> The main difference between them is that a primary key is unique but there can be many candidate keys. </em>

I hope you find this information useful and interesting! Good luck!

iVinArrow [24]

The available options are:

A. localhost/Carla/hello.php

B. localhost/htdocs/hello.php

C. localhost/htdocs/Carla/hello.php

D. carla/hello.php5

Answer:

C.  localhost/htdocs/Carla/hello.php  

Explanation:

A path in computer programming can be defined as the name of a file or directory, which specifies a unique location in a file system.

Therefore, to get the correct path to enter to view this page in a browser, one needs to follow the directory tree hierarchy, which is expressed in a string of characters in which path components, separated by a delimiting character, represent each directory.

Hence, correct path to enter to view this page in a browser is "localhost/htdocs/Carla/hello.php"
