Perl programing language
Perl is a very high-level
programming language originally developed in the 1980s by Larry Wall. Perl is
now being developed by a group of individuals known as the Perl5-Porters under
the watchful eye of Larry. One of Perl's many strengths is its ability to
process arbitrary chunks of textual data, known as strings , in many powerful ways, including
regular-expression string manipulation. This capability
makes Perl an excellent choice for database programming, since the majority of
information stored within databases is textual in nature. Perl takes the pain of
manipulating strings out of programming, unlike C, which is not well-suited for
that task. Perl scripts tend to be far smaller than equivalent C programs and
are generally portable to other operating systems that run Perl with little or
no modification.
Perl also now features the ability to dynamically load external
modules , which are
pieces of software that can be slotted into Perl to extend and enhance its
functionality. There are literally hundreds of these modules available now,
ranging from mathematical modules to three-dimensional graphics-rendering
modules to modules that allow you to interact with networks and network
software. The DBI is a set of modules for Perl that allows you to interact with
databases.
In recent years, Perl has become a standard within many
companies by just being immensely useful for many different applications, the
"Swiss army knife of programming languages." It has been heavily used by system
administrators who like its flexibility and usefulness for almost any job they
can think of. When used in conjunction with DBI, Perl makes loading and dumping
databases very straightforward, and its excellent data-manipulation capabilities
allow developers to create and manipulate data easily.
