firebase-db-practice

This is a simple firebase CRUD operation practice code in which you enter your basic contact data such as name, email and phone number.
The data entered, on submit gets written in firebase realtime database.
After that when you go to viewData page it reads all the entries stored in database.
Also infront of each row you'll have two options one to save and the other to delete the entry.
To update a record simply click on that particular field, edit it and save the changes.
If you want to delete a particular record simply click on delete button of that particular row.
