+The AdventureWorks databases are sample databases that were originally published by Microsoft to show how to design a SQL Server database using SQL Server 2008. AdventureWorks is the OLTP sample, and AdventureWorksDW is the data warehouse sample.

Therefore, if you install AdventureWorks2014 on SQL Server 2016, the database will not be running at the compatibility level for SQL Server 2016. When this happens, new features in SQL Server might not work on the sample database.

Database design has changed since SQL Server 2008, and so AdventureWorks does not always exhibit the best practices of designing a database with the latest features of SQL Server. For compatibility with existing AdventureWorks examples, we continue to publish a version-bump of AdventureWorks for each new release of SQL Server.

 To install the AdventureWorks databases with the database compatibility level of your SQL Server instance, you can install from a version-specific backup file or from the install script.
