Microsoft SQL Server 2014 is a DBMS for Windows platforms. It is used to build, deploy, and manage locally hosted or cloud-based applications.
Features of SQL Server 2014
The latest version of SQL Server 2014 has the following benefits :
The new in-memory capabilities for online transaction processing (OLTP) built into SQL Server accelerate online transaction performance by up to 30 times.
An improved and updatable in-memory column base enhances the benefits of compression. In use, query performance is up to 100 times faster, and data compression gains up to 90 percent. Such storage savings, coupled with query acceleration, can handle much larger data volumes.
New hybrid capabilities include simplified backup to Azure and the ability to configure an Azure Always virtual machine as a secondary replica always available. A disaster recovery configuration is achieved at a lower cost that allows for quick recovery.
Azure’s new in-memory OLTP technology enables the use of the parallel processing architecture in transaction processing to improve VM consistency, performance, and scalability.
In addition to the core database engine, depending on the database edition, SQL Server 2014 provides integration, analysis, reporting, master data, and data quality services. Other components of SQL Server 2014 include StreamInsight, which supports streaming, and management and development tools.
