Yes. So far as your data falls within its allowable limit and you doesnt require any extended features you can use it.

Yes,

I am also using for some small application.

YOu have clear with your express feature like memory limit,sql aget is not there so can not schedule job.

Tips:- You can schedule job using script in sqlcmd  for windows scheduler.

You can take backup regularly and remove old backup job schedule by windows scheduler.

SQL Server Express can be used in commercial applications. As long as your needs don't exceed the limitations on Express, you should be good to go.

Hi the link for redistibution rights is broken 

Can you please provide updated link?

Hi Dinesh

Have you registered it for redistribution rights?

Can you explain this process bit more?

Hi ark1231,

the link for redistibution rights is broken 

Based on my research, starting with SQL Server 2012 the redistribution rights are built into the SQL Server Express license, and registration is no longer required to redistribute this version of SQL Server Express.

For more details, please review the following thread.
