1. 8 LAB - Create index and explain (Sakila)
Refer to the table of the Sakila database. This lab loads with 100 rows from Sakila. Consequently, generates too many characters to display in the zyLab environment. However, statements with less output, such as , execute successfully. FilmfilmSELECT * FROM film;SELECT title FROM film;
This lab illustrates the use of indexes and EXPLAIN to optimize query performance. Refer to EXPLAIN documentation for information about EXPLAIN result columns.
Write and run seven SQL statements:
Explain the query. SELECT * FROM film WHERE title = 'ALONE TRIP';
In the EXPLAIN result, column key is null, indicating no index is available for the query. Column rows is 100, indicating all rows are read. The query executes a table scan and is slow.
Create an index on the column. Idx_titletitle
Explain the query of step 1 again.
In the EXPLAIN result, column key has value idx_title, indicating the query uses the index on title. Column rows is 1, indicating only one table row is read. The query is fast.
Explain the query. SELECT * FROM film WHERE title > 'ALONE TRIP';
In the EXPLAIN result, column key is null, indicating the query does not use the idx_title index. Column rows is 100, indicating all rows are read. Since the query has > in the WHERE clause rather than =, the query executes a table scan and is slow.
Explain the query SELECT rating, count(*) FROM film GROUP BY rating;
In the EXPLAIN result, column key is null, indicating no index is available for the query. Column rows is 100, indicating all rows are read. The query executes a table scan and is slow.
Create an index on the column. Idx_ratingrating
Explain the query of step 5 again.
In the EXPLAIN result, column key has value idx_rating, indicating the query reads rating values from the index. The query uses an index scan, which is faster than a table scan (step 5).
For submit-mode testing, all seven statements must appear in Main. Sql in the correct order.
NOTE: In submit-mode tests that generate multiple result tables, the results are merged. Although the tests run correctly, the results appear in one table
Below is the given SQL statements a person can use: For one to Explain the query: the sql will be:
SELECT * FROM film WHERE title = 'ALONE TRIP';
What is the index about?For one to make an index on the area of the title column, the sql will be
CREATE INDEX Idx_title ON film (title);
For one to be able to explain the query that is in the step 1, one need to use the sql of
EXPLAIN SELECT * FROM film WHERE title = 'ALONE TRIP';
In regards to the submit-mode testing, note that all seven statements needs to show in the Main.sql and also in the correct order. That is in submit-mode tests that brings about the multiple result tables, the results are said to be merged into a single table.

An elevated master stream device mounted at the tip of an aerial ladder is a __________.
An elevated master stream device mounted at the tip of an aerial ladder is a ladder pipe.
What is an elevated master stream device?Master streams are a useful weapon for fighting and putting out fires, particularly in defensive circumstances or when a safe distance must be maintained while pumping a lot of water.
Master streams, such as those attached to a truck or aerial equipment, have a capacity of 500 to 2,500 gpm at 100 psi. With a 100-psi nozzle, the water is moving at a rate of around 120 feet per second, or 80 miles per hour.
In attempts to put out fires or remove potential dangers like chimneys, we have witnessed the impact of using a master stream to push or knock over structures like walls or chimneys. Water pressure may be quite damaging.

A.What is the maximum core diameter for a fiber if it is to operate in single mode at a wavelength of 1550nm if the NA is 0.12?
B.A certain fiber has an Attenuation of 1.5dB/Km at 1300nm.if 0.5mW of Optical power is initially launched into the fiber, what is the power level in microwatts after 8km?
The maximum core diameter for the fiber to operate in single mode at a wavelength of 1550nm with an NA of 0.12 is approximately 0.0001548387.
To determine the maximum core diameter for a fiber operating in single mode at a wavelength of 1550nm with a given Numerical Aperture (NA), we can use the following formula:
Maximum Core Diameter = (2 * NA) / (wavelength)
Given:
Wavelength (λ) = 1550nm
Numerical Aperture (NA) = 0.12
Plugging these values into the formula, we get:
Maximum Core Diameter = (2 * 0.12) / 1550
Calculating the result:
Maximum Core Diameter = 0.24 / 1550
≈ 0.0001548387
