Your First Task At Big Data Datacenter Is To Show Some Simple Proof Of
Your first task at Big Data Datacenter is to show some simple proof of concept types of activities. You will need Perl for the proof of concept activities, so you should download it if it is not already installed on your system. Management is eager to see how Perl can connect and interact with databases and common gateway interface (CGI) applications. For the database connection, you will need to download and install the database interface driver (DBI) and show the following using the Big_Data_Servers_Table.xlsx as your guide: A connection to a database A query from the database that returns all of the servers that have status of production An insert into the database that adds a new server to the table with ("PERLBD4",128.33.23.198, "Development") An update to the database that changes PERLDB2 from development status to production status A delete on the database that removes the record information for PERLDB1 because it is no longer in service.
For the CGI test, you should connect to the same data source and return the following: The number of rows in the Big_Data_Servers_Table.xlsx A query that shows all of the production servers Use the attached spreadsheet as your guide. Your database and CGI tasks should reflect the actions against the spreadsheet as if it were a table in a database. You can optionally download and install a small database and load it with the data from the spreadsheet. A simple, lightweight database will do, such as one of the following: Option 1 Option 2. Complete the following: Provide a 2-paragraph summary on how you might use DBI and CGI to manage and report on information in a database. Share the syntax that is required to perform the DBI and CGI tasks. Simply cut and paste the Perl commands that you are using into a Word document.
Paper For Above instruction
The integration of Perl with database management and CGI scripting offers an effective method for managing and reporting on data within a web environment. Using Perl's DBI module, developers can establish connections to various databases such as MySQL, SQLite, or PostgreSQL, enabling seamless execution of SQL queries for data retrieval, insertion, updating, and deletion. This process simplifies complex data operations by providing a straightforward interface through Perl scripts, facilitating automation and efficient data handling in server-side applications. Additionally, CGI scripts written in Perl can interact with databases to dynamically generate web pages that display current data status, execute user-driven queries, and allow data modifications directly from a web interface. This combination not only improves operational efficiency but also enhances accessibility and decision-making by providing real-time data reports through web pages.
To perform DBI and CGI tasks in Perl, specific syntaxes are used to connect and manipulate data sources. First, establish a connection to the database using:
my $dbh = DBI->connect("dbi:mysql:database_name", "username", "password")
or die "Could not connect to database: $DBI::errstr";
Next, execute a query to retrieve all production servers:
my $sth = $dbh->prepare("SELECT * FROM Big_Data_Servers_Table WHERE status = 'production'");
$sth->execute();
while (my @row = $sth->fetchrow_array) {
print "@row\n";
}
For inserting a new server:
my $insert = $dbh->prepare("INSERT INTO Big_Data_Servers_Table (ServerName, IP, Status) VALUES ('PERLBD4', '128.33.23.198', 'Development')");
$insert->execute();
To update a server’s status:
my $update = $dbh->prepare("UPDATE Big_Data_Servers_Table SET Status='production' WHERE ServerName='PERLDB2'");
$update->execute();
And for deleting a server:
my $delete = $dbh->prepare("DELETE FROM Big_Data_Servers_Table WHERE ServerName='PERLDB1'");
$delete->execute();
For CGI scripts, retrieving the number of rows:
use CGI;
my $query = CGI->new;
my $sth = $dbh->prepare("SELECT COUNT(*) FROM Big_Data_Servers_Table");
$sth->execute();
my ($count) = $sth->fetchrow_array;
print $query->header(), $query->start_html('Server Count'), "
Total servers: $count
", $query->end_html;
And to display all production servers:
my $sth = $dbh->prepare("SELECT * FROM Big_Data_Servers_Table WHERE Status='production'");
$sth->execute();
print $query->header(), $query->start_html('Production Servers');
while (my @row = $sth->fetchrow_array) {
print "
@row
";
}
print $query->end_html;
These syntax examples demonstrate effective management and reporting functionalities that can be achieved through Perl’s DBI module coupled with CGI scripting, thus enabling dynamic interaction with data in a web-based environment.
