Databases store data in the database files. The DBI module in Perl enables us to work with the database. We can access the data stored in the databases and retrieve valuable information. Structured Query Language is the language used to communicate with the database. In this chapter we will learn how to connect and disconnect from a database. In addition, we will learn how to work with the data in the database using SQL queries.Working with DatabasesWe use a telephone diary to store the...
The pretest and posttest engine allowed creating different sets of test questions (in multiple-choice question format) for different lessons or chapters.
