4.7 Perl
Perl stands for Practical Extraction and Report Language. It is an interpreted
language optimized for scanning text files and extracting information from these
text files. It is influenced by a variety of languages such as AWK, C, Lisp, and
shell scripts. It supports different programming paradigms such as procedural,
object-oriented, and functional. There is also a large collection of third party
modules, which makes Perl even more useful. Because of these reasons, Perl is
widely used in system administration, network programming, as well as Web
development along with text manipulation.
Perl has the ability to access a wide variety of databases through DBI (Database
interface module). DBI defines a set of methods and conventions that you can
use independent of the database being used. IBM Perl driver conforms to this
DBI specification. This driver is an open source.
4.7.1 DBD::DB2
DBD::DB2 is the IBM provided database driver module that implements DBI for
accessing IBM DB2 databases. It is supported on Perl version 5.6 and greater.
You can use this driver to connect to IBM DB2 version 8.2 and greater and all
DB2 supported operating system platforms. You can use features of DB2 such
as issue SQL queries, call stored procedures, and work with large objects.
