How do APIs Work
• Imagine APIs (Application Interface) as a
standardised set of functions that allow
programs to access databases and execute
SQL statements on that database
• There are APIs for PHP, PERL, Java ... To work
with databases e.g. MySQL
• To connect you need to execute your
commands as a specific user which you need to
set up first (see previous slides)
