The first and the main thing about this application is its name. PL-SQL FYI is basically PL-SQL For Your Information (FYI). As its name suggests its an informative application.
This application consists of information regarding the PL-SQL concepts , commands and information about those commands along with the examples.
Specified information is taken from some of the Oracle Documents, Oracle websites and Oracle study materials.
I started making the app for myself but now its done so this reference guide can be useful to others as well and this will help people to know about PL-SQL. Nothing bad in spreading information worldwide and help people to learn. No need of hard copies of documents. Carry the app in your pocket and read the contents anywhere. Feel free to send your inputs to me.
