Create a short document titled "Guide to web searches" that Sergio can give to users of the facility he supervises. The document

Answer:

Jobs Seeker's

Web Search Guide

Sergio Escobar

PERFORMING A SEARCH:

All search engines will have a search field in which you are able to enter your search terms,

criteria, keywords, or even a website.

Search terms are the keywords a search engine will use to try to find the most relevant search

results.

If you’re looking for general information, just enter the name of the topic you’re

interested in into the search field.

So, if you’re looking for work, you can use the search terms ‘employment’ and ‘jobs’.

The search engine will return you a list of web pages that include the words

‘employment’ and ‘jobs’.

IF you’re looking for more specific information, you can narrow your search results by

using more specific search terms.

So, if you wanted employment opportunities in Phoenix, AZ, you could use the search terms:

‘local’, ‘employment’, ‘jobs’ and ‘Phoenix’.

Once you’ve entered your search terms and selected the search or go button, the search

engine will provide you with a list oF search results.

Depending on your search, you could get thousands or even millions of search results. This is

because search engines will usually list every single web page on the Internet that used those

search terms somewhere on a web page.

(However, the most current and/ or relevant results should be at the top of the list.)

Searching Strategy:

Using Boolean Operators:

use AND,OR,NOT between the words

ex: LOCAL AND JOBS

JOBS NOT IN NEWYORK

Proximity Operators:

With some search engines you can use proximity operators such as OpenText's NEAR operators or Webcrawler's ADJecent or the FOLLOWED BY operator.

With each of these operators, word order is important.

For example: if you place square brackets such as [local jobs] causes a hit if they are found within 100 words of each other.

Truncation (*)

You can use truncation on most search engines.

That is, you can use the asterisk (*) operator to end a root word.

For example: searching for comput* will find computer, computing, and computer jobs.

Note: the asterisk can not be the first or second letter of a root word.

Wildcard (?)

You can find words that share some but not all characters using the question mark (?) operator.

For example: Com?er J?b will find Computer Jobs and Computer Job.

Note: the ? can not be the first character in the search.

You may also use combinations of truncation (*) and single character wildcard (?) in your searches.

Conclusion:

These are just a few of the strategies and new tools trainers can use to make working on the web more productive.

As trainers continue to use the web they will soon see the next generation of web "knowledge tools" begin to emerge.

These will include multidimensional tools that are created to manage data on the web using factors such as "virtual neighborhoods of information,

" "organic structuring," and "mental model based searching and flying mechanisms" .

These are tools which are intended to make the world wide web more manageable for the user.

Let us now go back to my original statement...that the goals of search strategies and engines should be to increase your efficiency

and effectiveness when looking for information on the web.

Only you can decide which search/knowledge management strategies and tools actually improve your productivity.

It is my hope that this article helps you with making these decisions.

Write a SELECT statement that returns one row for each customer that has orders with these columns:
d1i1m1o1n [39]

Answer:

SELECT email_address,

SUM(item_price * Quantity) AS item_price_total,

SUM(discount_amount * Quantity) AS discount_amount_total

FROM Customers c

JOIN Orders o ON c.CustomerID = o.CustomerID

JOIN Order_Items oi ON o.OrderID = oi.OrderID

GROUP BY email_address

ORDER BY item_price_total DESC

Explanation:

In this SQL statement the SELECT statement selects the following columns:

email_address

item_price

Quantity

discount_amount

There are two tables Customers and Order_Items

SUM aggregate function is used to add the values of the product of the columns discount_amount and Quantity. It is also used to get the sum of the product of two columns discount_amount and Quantity.

A new temporary column named item_price_total is used to name the sum of the product of two columns discount_amount and Quantity using AS which is ALIAS and it is used to give a name to some columns or a table.

Similarly discount_amount_total name is given to the column which calculate the sum of the product of two columns i.e. discount_amount and Quantity.

JOIN is used here to join the columns from the tables Order_items and Customers.

GROUP BY is used to group the result of rows and is used with functions like SUM. Here the rows are grouped by the email address.

ORDER BY is used to order the result. Here the result is ordered by item_price_total in descending  order.

This SELECT statement can also be written as following:

SELECT c.email_address,

SUM(o.item_price * o.Quantity),

SUM(o.discount_amount * o.quantity)

FROM customer c

JOIN Order_Items o ON o.id = c.id

GROUP BY c.email_address
