Attach Content Database with SharePoint WebApplication

I am going to explain how to attach a content database with SharePoint Web Application. Follow the below steps to attach DB

• First Restore the content database in local sql server
• Open the powershell, first test the db for safer side. Give  Test-SPContentDatabase -name yourcontentdbname -WebApplication "yourwebapplication"
• It will give some exception if the DB is not attachable with web application
• Then mount the database,  Mount-SPContentDatabase "yourcontentdbname" -WebApplication yourwebapplicationname
• It will show the progress of mounting DB
• We will get 100% notification once DB mounted
