Why Should I Check Out a MySQL-Based Column Database ?

Some technologies come on the information technology landscape and stay, providing long-lasting benefits, whereas others are more of a short term fad and ultimately end up disappearing because the value they supplied was too niche oriented and/or they were quickly supplanted by another technology that is better. Recently, articles, blogs, analyst reports, and other media outlets have been noting the rise and usage of column-oriented databases in the areas of data warehousing, analytics, and other business intelligence/read-intensive situations. And on the MySQL front, there are a couple of column DB's that are now available for you to use. Are column-oriented databases a technology that is destined to stay and provide long-term benefits or will it be relegated to the forgotten pile of other software that came on the scene quickly and then disappeared?

MySQL::Diff(3pm)					User Contributed Perl Documentation					  MySQL::Diff(3pm)

NAME

       MySQL::Diff - Generates a database upgrade instruction set

SYNOPSIS

	 use MySQL::Diff;

	 my $md = MySQL::Diff->new( %options );
	 my $db1 = $md->register_db($ARGV[0], 1);
	 my $db2 = $md->register_db($ARGV[1], 2);
	 my $diffs = $md->diff();

DESCRIPTION

       Generates the SQL instructions required to upgrade the first database to match the second.

METHODS

   Constructor
       new( %options )
	   Instantiate the objects, providing the command line options for database access and process requirements.

   Public Methods
       Fuller documentation will appear here in time :)

       o   register_db($name,$inx)

	   Reference the database, and setup a connection. The name can be an already existing 'MySQL::Diff::Database' database object. The index
	   can be '1' or '2', and refers both to the order of the diff, and to the host, port, username and password arguments that have been
	   supplied.

       o   db1()

       o   db2()

	   Return the first and second databases registered via "register_db()".

       o   diff()

	   Performs the diff, returning a string containing the commands needed to change the schema of the first database into that of the
	   second.
