What were the differences between the auburn system and the Pennsylvania system?

The Auburn System

The Auburn prison system, often referred to as the "congregate system," is first implemented in 1819 at the New York State Prison at Auburn. Though it too incorporates Quaker ideals of reformation - humane conditions from bedding to health care, strict routines, and religious contemplation - it is considered a less pure model than the Philadelphia system. Prisoners are together, side by side, during work, meals, and prayer but return to solitary cells at night. Silence is enforced at all times, even among groups. Usually, the inmates' work consists of hard labor, such as the construction of roads or buildings. This is considered the route to repentance and salvation. Inmates march in unison, in a formation known as the lock step, which will remain in use at many prisons into the 21st century.

Auburn introduces the tier system, different levels of cells built above one another, in which convicts are housed according to their offense category - first timers vs. repeaters, murderers vs. thieves, and so forth. Inmates wear uniforms of different colors, depending on their classification. The work regimen produces income that the Pennsylvania system could not generate, and this system is by far more cost effective and practical. Inmates are less likely to go mad, and it is easier to feed everyone in a group. The Auburn philosophy quickly becomes the model for prisons nationally and internationally.

The Pennsylvania system,

which is also known at the separate system, encouraged solitary confinement for the prisoners. The Pennsylvania system was the leading influence in penology for over a century and was the forerunner of modern corrections. It was designed to keep prisoners separate even as they worked in-order to keep the inmates from being distracted and impeding their repentance. The idea was originally developed by the Philadelphia Society for Alleviating the Miseries of Public Prisons, whose most active members where Quakers.

What are key features of the DNS database?

The DNS database features a distributed hierarchical tree structure containing what are called resource records (RR) of various types: Start of Authority (SOA), IP addresses, SMTP mail exchanges, name servers, pointers for reverse look ups, and domain name aliases. DNS is a naming system for any device connected to either the Internet or to a private network. See the ICANN web site for more information.

What is an Entity Relationship diagram for library management database?

An entity relationship diagram is a graphical documentation of a database's tables, fields, and the relationships between tables in the database. It shows all of the fields in each of the tables, and sometimes describes the data types for those fields as well as having lines between the tables that show relationships. The relationships can be one-to-many, or one-to-one relationships. A one-to-many (the most common) relationship means that one row in one of the tables will relate directly to many rows in the other table (hence the reason the data is in two tables.) One-to-one relationships are use to separate data that could be located in the same table as the other data into multiple tables.

Entity relationship diagrams are helpful when querying a database as well to understand how to write the SQL to pull the data out of the database. These diagrams are useful to database designers, database administrators, computer programmers, and database users to understand the structure of the database.

What is the purpose of creating views in DBMS for existing tablesIf we update the created view of a table will the changes be reflected in the original table always?

A view is generally used to provide a subset view of a table. This can be for security or clarity. For example, you have a payroll table like so:

nameaddresscitystatezipphonesupervisorsalarylast_paycheck_dateno_demeritsnotes

And you only want to have an employee see name, address, phone number, and supervisor, then they can't see hr information. Similarly, if you have multiple tables and need only 5 or 6 fields, then you can use a view to select only those fields.

A view also has the advantage that it uses less resources on the SQL server side because the SQL code is already compiled, and (in some cases), the SQL server keeps the data references up-to-date, so as not to have to find them every time it's run.

This is a very basic overview, but covers the gist of the question.

Components of distributed database management system?

=A database physically stored in two or more computer systems.

How do you retrieve data stored in the database into the dropdown using PHP?

<select name="select1">

<option value="">Please Select...</option>

<?php

$fetchQuery = mysql_query("SELECT * FROM `table`");

while($showOutput = mysql_fetch_object($fetchQuery)){

echo "<option value="{$showOutput->value1}">{$showOutput->value2}</option>";

}

?>

</select>

Using the while function is very useful. If you wish to limit the amount of outputted lines, use LIMIT 10 at the end of the mysql query.
