Restore database improve code

let me know if you can suggest any improvement in my code. I think i have too many ECHO.

Code:

#! /bin/bash

DATABASE=$1
DATE=$2
MYLOGIN=/home/dbadmin/login_dev.ini
BKUP_FILE=/home/dbadmin/delete
DB_NAME=$DATABASE.sql.gz


DBEXISTS=$(mysql --defaults-extra-file=$MYLOGIN --batch --skip-column-names -e "SHOW DATABASES LIKE '"$DATABASE"';" | grep "$DATABASE" > /dev/null; echo "$?")


if [ $DBEXISTS -eq 0 ];then
    clear
	
	echo ".........................................................................."
	echo "$DATABASE already exists. Back up and drop $DATABASE before running restore_full_db.sh. Exiting..."
	echo ".........................................................................."
	echo ""
	echo ""
	
	exit
else 	

	if [ -f $BKUP_FILE/$DATE/$DB_NAME ] 
		then
		
			clear
		
			echo "$DB_NAME decompressed"
			echo ".........................................................................."
			gzip -d $BKUP_FILE/$DATE/$DB_NAME
			echo ""
			echo ""
			echo ""

			echo "$DATABASE created"
			echo ".........................................................................."
			mysql --defaults-extra-file=$MYLOGIN <<< "create database $DATABASE"
			echo ""
			echo ""
			echo ""

			echo "Data restoring in $DATABASE"
			echo ".........................................................................."
			mysql --defaults-extra-file=$MYLOGIN "$DATABASE" < "$BKUP_FILE/$DATE/$DATABASE.sql"
			echo ""
			echo ""
			echo ""
			echo "Data restored. Exit..."
			echo ""
			echo ""
			echo ""

		else
			
			echo ".........................................................................."
			echo "$DB_NAME file not found. Exiting..."
			echo ".........................................................................."
			echo ""
			echo ""
			
			exit
	fi
