In this case, AdventureWorks2012 sample database was installed. The downloaded is zip file, so it needs to be unzipped saved in SQL Server backup folder. Since there was no change made during installation process, the location of files was in C:\Program Files\Microsoft SQL Server\MSSQL11.SQL2012EXPRESS\MSSQL\Backup.

Since there was no any other file selected in the Select backup device window. The command prompted to the Restore database window. The AdventureWork database was restored and ready for use as shown in the screen shot below.
SQL stands for Structured Query Language, which means that it does not depend on ISO SQL and ANSI standard syntax for operations, instead it uses Transact-SQL (T-SQL). Also, it is important to understand that SQL Server is presented as relational database since it stores data in relations. The relations should not construed to mean relationship between one data set with another, but it is a mathematical term meaning a collection of unordered tuples and unique sets of values or attributes. Therefore, SQL Server are represented in tables, which is a collection of columns and rows. It is therefore the tables that need to be query.
