1. What is JDBC?
JDBC is briefly a programming interface (API), which allows communication with the databases in a standardised way.
JDBC drivers are a set of Java classes, developed for a particular version of a particular database, adjusted to the JDBC
standard and providing standard functions, and are located in a directory structure or a file with ZIP or JAR extension
in an appropriately organised order. (JAR is basically a file of ZIP type.) To build up a database connection, the
program loads the driver found at the entered location into the memory and builds up the connection through its standard
functions.
