Hi Naka,

As XSS vulnerable web applications takes input and gives output without
filtering.
Using bind variable you can validate input and give output accordingly.
Another way is detailed code review that searches the code for validation
for all headers, cookies, query strings, form fields, and hidden
fields(i.e., all parameters) against a rigorous validation of what should be
allowed.

Stored PL/SQL is faster because it parses only ones and resides in main
memory and further request doesn't require re-parsing.
For example if a 100 line SQL statement accessed by 100 clients. It has to
compile 100 x 100 times. Same thing can be achieved in PL/SQL block in
compiling only once.
Rich family of In-built function also makes it faster as compare to other
languages.
It’s good to perform DML operations in PL/SQL rather than using methods of
other languages, as they require heavy processing to perform the same
actions.
