Catalog Description:
Computer Science 44B - Perl Programming II
2 units
Using Perl Modules, Object-oriented Perl, and Perl with the World Wide Web. Perl with sockets,
CGI, databases, HTTP/HTML, mail, forms, Web servers and other Internet resources. Prerequisite:
Computer Science 44A, Computer Science 91 or Computer Application Systems 91 or Electronics
and Computer Technology 91 and Computer Science 40A or Computer Science 47A (all completed
with a grade of C or higher). 1.5 hours lecture, 1.5 hours laboratory.
Prerequisite Skills:
Before entering the course the student should be able to:
1. demonstrate knowledge of the control structures of Perl;
2. use scalar and array variables, operators, lists, hashes, regular expressions, files and data,
pipes, references, and subroutines;
3. run and debug a Perl program in the Unix or Linux and Windows environments;
4. construct related data tables using primary/foreign key relational integrity rules;
5. produce data entry forms that ensure data integrity;
6. construct queries by QBE (query by example) and directly in SQL;
7. produce reports that present data results in a meaningful and usable manner;
8. link Access to the SQL Server database;
9. use HTML to create a Web page;
10. use SQL to access either an Oracle or an MS Access database.
Expected Outcomes for Students:
Upon completion of the course the student should be able to:
1.

use Perl Modules;
use Perl in an object-oriented manner;
describe the basics of the CGI (Common Gateway Interface) standard;
write Perl applications to use CGI to access a Web server such as Apache;
access a database using simple SQL queries from Perl using DBM or DBI;
access Internet services in Perl;
use Unix system services such as processes, signals, network services, sockets, and the inetd
daemon from within Perl;
8. use Perl for accessing graphical interfaces, such as the GTK+ and Gnome, use other selected
Perl services: the math routines, including BigInt and BigFloat; the security and cryptography
module; the complex number routines; or the Perl Data Language as time permits.
