Chapter 4. Programming with the DBI
In this chapter, we’ll discuss in detail the actual programming interface defined by the DBI module. We’ll start with the very architecture of DBI, continue with explaining how to use the handles that DBI provides to interact with databases, then cover simple tasks such as connecting and disconnecting from databases. Finally, we’ll discuss the important topic of error handling and describe some of the DBI’s utility methods and functions. Future chapters will discuss how to manipulate data within your databases, as well as other advanced functionality.
