What are Solutions and Projects in SQL Server Managment Studio?

When you are working on a SQL Server Database related problem you may design Tables, Views, Stored Procedures and sometimes it may involve components other than the Data Engine. SQL Server Management Studio provides a means to group together all your codes in one place as part of a SQL Server Project. A solution is a container for a project(s) containing all logically related scripts and files in one place. It is available even in SQL Server 2012 Express. This is the platform to use if you want to develop scripts for Database Engine and Analysis Services. SQL Server is tightly integrated with Visual Studio,
