The social media app you are designing a database for allows Users to.pdfStewartxCYTurnerq
The social media app you are designing a database for allows Users to share two kinds of
content: **Messages** and **Stories**.
Tables structure
Decide what fields and data types are necessary for the two tables necessary for this app: `users`
and `posts`. The `posts` table stores both Messages and Stories.
Bear in mind that the application must be able to use these tables to perform the required
functionality outlined below.
Users:
Users can register for the app by supplying their...
- email
- password
- handle (i.e. username).
Messages:
- Messages consist of text only.
- Messages are sent from one user to another specific user.
- Messages become invisible immediately after view and don't show up in the app thereafter.
- Messages are never actually deleted from the database table, even when invisible to the user
(the social media company that produces the app keeps 'deleted' content in its database for future
data harvesting, monetization purposes, and more.)
Stories:
- Stories consist of text only.
- Stories are public and every user can see them.
- Stories become invisible 24 hours after posting and don't show up in the app thereafter.
- Stories are never deleted from the database table, even when invisible to the user.
Write the SQL command to create these tables with the structure you determine is necessary.
### Practice data
Insert realistic-looking dummy data for one thousand Users, one thousand Messages, and one
thousand Stories.
Include the practice data in CSV files named `users.csv` and `posts.csv` in the directory named
`data`.
Write the SQLite commands necessary to import the data into the respective tables.
### Queries
Write a single SQL query to perform each of the followin tasks:
1. Register a new User.
1. Create a new Message sent by a particular User to a particular User (pick any two Users for
example).
1. Create a new Story by a particular User (pick any User for example).
1. Show the 10 most recent visible Messages and Stories, in order of recency.
1. Show the 10 most recent visible Messages sent by a particular User to a particular User (pick
any two Users for example), in order of recency.
1. Make all Stories that are more than 24 hours old invisible.
1. Show all invisible Messages and Stories, in order of recency.
1. Show the number of posts by each User.
1. Show the post text and email address of all posts and the User who made them within the last
24 hours.
1. Show the email addresses of all Users who have not posted anything yet.
### Hint
The following SQLite code returns the difference in hours between the time now and an earlier
date and time - this may be useful in determining the number of hours that have passed since a
post was made: `ROUND((JULIANDAY('now') - JULIANDAY('2021-02-21 12:50:00')) * 24)`
To see the return value of this command directly (not as part of a comparison operation), use the
following syntax: `SELECT ROUND((JULIANDAY('now') - JULIANDAY('2021-02-21
12:50:00')) * 24);`

The Saint Lucia Blood Bank- a private charity partly supported by gove.pdfStewartxCYTurnerq
The Saint Lucia Blood Bank, a private charity partly supported by government grants, is located
on the Caribbean island of Saint Lucia. The blood bank has just finished its operations for
September, which was a very busy month due to a powerful hurricane that hit neighboring
islands causing many injuries. The hurricane largely bypassed Saint Lucia, but residents of Saint
Lucia willingly donated their blood to help people on other islands. As a consequence, the blood
bank collected and processed over 20% more blood than had been originally planned for the
month. A report prepared by a government official comparing actual costs to budgeted costs for
the blood bank appears below. Continued support from the government depends on the blood
bank's ability to demonstrate control over its costs. The managing director of the blood bank was
very unhappy with this report, claiming that his costs were higher than expected due to the
emergency on the neighboring islands. He also pointed out that the additional costs had been
fully covered by payments from grateful recipients on the other islands. The government official
who prepared the report countered that all of the figures had been submitted by the blood bank to
the government; he was just pointing out that actual costs were a lot higher than promised in the
budget. The following cost formulas were used to construct the planning budget: Required:
1.Complete the flexible budget performance report for September. (Indicate the effect of each

The Saint Lucia Blood Bank- a private charity partly supported by gove.pdfStewartxCYTurnerq
The Saint Lucia Blood Bank, a private charity partly supported by government grants, is located
on the Caribbean island of Saint Lucia. The blood bank has just finished its operations for
September, which was a very busy month due to a powerful hurricane that hit neighboring
islands causing many injuries. The hurricane largely bypassed Saint Lucia, but residents of Saint
Lucia willingly donated their blood to help people on other islands. As a consequence, the blood
bank collected and processed over 20% more blood than had been originally planned for the
month. A report prepared by a government official comparing actual costs to budgeted costs for
the blood bank appears below. Continued support from the government depends on the blood
bank's ability to demonstrate control over its costs. The managing director of the blood bank was
very unhappy with this report, claiming that his costs were higher than expected due to the
emergency on the neighboring islands. He also pointed out that the additional costs had been
fully covered by payments from grateful recipients on the other islands. The government official
who prepared the report countered that all of the figures had been submitted by the blood bank to
the government; he was just pointing out that actual costs were a lot higher than promised in the
budget. The following cost formulas were used to construct the planning budget: Required:
1.Complete the flexible budget performance report for September. (Indicate the effect of each
variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero
variance). Input all amounts as positive values.).

The reason the medical community prefers to use the term -sexually tra.pdfStewartxCYTurnerq

symptoms or signs b) the term "infection" tends to be less stigmatized than "disease," and may
make it more likely for people to seek medical care c) infections may progress to become
diseases, but only if the correct set of conditions exists to do so d) all of the above.
