What are the basics of working with relational databases in Perl?

Working with relational databases in Perl involves establishing connections, executing SQL queries, and processing the retrieved data. Perl provides various modules that simplify the interaction with databases, including DBI (Database Interface) and DBD (Database Driver) modules. Let's explore the basics of working with relational databases in Perl: 1. Installing and Importing Modules: * Begin by installing the required database-specific DBD module from CPAN (Comprehensive Perl Archive Network). For example, if you're working with MySQL, install `DBD::mysql`. * Import the necessary modules into your Perl script using the `use` statement. Typically, you'll need to import the DBI module and the specific DBD module for your chosen database. 2. Establishing Database Connection: * To connect to a relational database, use the `DBI->connect()` method, providing the re....
