Microsoft’s RDBMS product for desktops and enterprise is the SQL Server and SQL Server 2012 is the version released to the market in 2012. The SQL Server 2012 evolved from the 2005 version. The SQL server code started out to be jointly owned by Microsoft and two other companies named Ashton Tate and Sybase. It was released as the desktop product on PS/2 with OS/2 environment back in 1989. By the time several upgrades were released to arrive at the sql server version 2005, Microsoft has own version of the code contributed by Ashton Tate by this time. The 2012 version evolved through 2008, 2008 R2 versions to become the SQL Server 2012.
The SQL Server 2012 grew into the SQL Server 2014 version and the latest product from Microsoft stable is the community technology preview 2016 that has just been released recently. The sql server 2012 adds two major trends to the feature list that was available with the previous 2008 R2 version.
With the SQL Server 2012, Microsoft decided to support only ODBC (open database connectivity). Even the interconnectivity between MS document types supported through OLE was to be dropped. The general release of the SQL Server 2012 came in Mar, 2012 followed by release of Service pack 1 in Nov 2012 and the pack2, in Nov, 2014. The added features include a PowerView. When creating business intelligence reports, you can mash up various data sets in SQL Server 2012 through this feature. Operationally, the AlwaysOn feature adds handling of database failures easier. Multiple copies created by the system in SQL Server 2012 helps make disaster recover quite straightforward. There is even a stripped down version which is not as resources hungry as the full version of the SQL Server 2012 but can let you carry out the most important operations. Programming features enhanced in the SQL Server 2012 include a ColumnStore indexes feature. These are read-only indexes that help optimizing processing queries on large data warehouses. Testing of the SQL Server 2012 procedures and queries can be played out (tried out) on a non-production server without risking crashes affecting your production operations. Operationally, an audit trail is a very important tool for systematic management of the database operations but a security safeguard against malicious activities, if any.
By this point in the development of the SQL Server product, SQL Server 2012 has evolved into an enterprise level DBMS with the ability to handle large volume of enterprise level data, supported by the administrative, program development and security features required for efficient operations. The next upgrade to SQL Server 2012 came in 2014.

This is a component that helps manage all the parts of the SQL Server. SQL Server Management Studio 2012 can do the following for all the software modules in the server:
SSMS is a crucial product and a critical piece in managing the database product; it is necessary to become familiar with the product first. Starting with the SQL Server Management Studio Express studio then seems to be a prudent approach. Getting the express version of the SQL Server, which includes the Management Studio could be downloaded from the Microsoft site. Installing the product should not create any problems. You should invest in a regular version after your team is comfortable with the SQL Server Management Studio 2012.
