developing the c# Winforms software using SQL Server-2012 in vs-2012 and
running it on other system without installing SQL Server 2012

i wanted to develop a c# application oriented software using
SQL-SERVER-2012 in VISUAL-STUDIO-2012. but if i install the software on
another computer with out installing SQL-SERVER-2012 database how this
software works and access the data?
Is there any method and function or namespace that can provide the default
storage space to store the data after the software is installed on a
system?
