About the time Windows NT was released in JulySybase and Microsoft parted ways and each pursued its own design and marketing schemes. Microsoft negotiated exclusive rights to all versions of SQL Server written for Microsoft operating systems. Data pages were enlarged from 2k bytes to 8k bytes. Extents thereby grew from 16k bytes to 64k bytes. Although there were pre-release versions of SQL as well as Windows compiled for Alpha, these were canceled and were never commercially released.
SQL Server included more modifications and extensions to the Sybase code base, adding support for the IA architecture now out buy sql server 2008 r2 standard edition 64bit software "mainstream" support [2]. Client tools, such as Enterprise Manager, would still need to be run from bit buy sql server 2008 r2 standard edition 64bit software clients. It included native support for managing XML data, in addition to relational data.
For this purpose, it defined an xml data type that could be used either as a data type in database columns or as literals in queries. XML is converted to an internal binary data type before being stored in the database. Specialized indexing methods were made available for XML data. When the data is accessed over web services, results are returned as XML. SQL Server has also been enhanced with new indexing algorithms, syntax and better error recovery systems.
Data pages are checksummed for better error resiliency, and optimistic concurrency support has been added for better performance. Permissions and access control have been made more granular and the query processor handles concurrent execution of queries in a more efficient way. Partitions on tables and indexes are supported natively, so scaling out a database onto a cluster is easier.
SQL Server introduced DMVs Dynamic Management Viewswhich are specialized views and functions that return server state information that can be used to monitor the health of a server instance, diagnose problems, and tune performance. SQL Server was the first version with native support for the x64 platform. Service Pack 1 SP1 of SQL Server introduced Database Mirroring, a high availability option that provides redundancy and failover capabilities at the database level.
Automatic failover requires a witness partner and an operating mode of synchronous also known as high-safety or full safety. Prior to SP1, it was not enabled by default, and was not supported by Microsoft. SQL Server also includes support for structured and semi-structured data, including digital media formats for pictures, audio, video and other multimedia data. In current versions, such multimedia data can be stored as BLOBs binary large objectsbut they are generic bitstreams.
Intrinsic awareness buy sql server 2008 r2 standard edition 64bit software multimedia data will allow specialized functions to be performed on them. Other new data types include specialized date and time types and a Spatial data type for location-dependent data. Backing up and restoring the database backs up or restores the referenced files as well.
The full-text search functionality has been integrated with the database engine. According to a Microsoft technical article, this simplifies management and improves performance.
Spatial data will be stored in two types. A "Round Earth" data type GEOGRAPHY uses an ellipsoidal model in which the Earth is defined as a single continuous entity which does not suffer from the singularities such as the international dateline, poles, or map projection zone "edges". SQL Server includes better compression features, which also helps in improving scalability. It also includes Resource Governor that allows reserving resources for certain users or workflows.
It also includes capabilities for transparent encryption of data TDE as well as compression of backups. The buy sql server 2008 r2 standard edition 64bit software SQL Server service pack SQL Server R2 However, the x64 platform would continue on in force. It was released to manufacturing on March 6, SQL Server 's new features and enhancements include Always On SQL Server Failover Cluster Instances and Availability Groups which provides buy sql server 2008 r2 standard edition 64bit software set of options to improve database availability, [36] Contained Databases which simplify the moving of databases between instances, new and modified Dynamic Management Views and Functions, [37] programmability enhancements including new spatial features, [38] metadata discovery, sequence objects and the THROW statement, [39] performance enhancements such as ColumnStore Indexes as well as improvements to OnLine and partition level operations and security enhancements including provisioning during setup, new permissions, improved role management, and default schema assignment for groups.
SQL Server was released to manufacturing on March 18,and released to the general public on April 1, and the build number was Whilst small tables may be entirely resident in memory in all versions of SQL Server, they also may reside on disk, so work is involved in reserving RAMwriting evicted pages to disk, loading new pages from disk, locking the pages in RAM while they are being operated on, and many other tasks.
By treating a table as guaranteed to be entirely resident in memory much of the 'plumbing' of disk-based databases can be avoided. SQL Server also enhances the Always On HADR solution by increasing the readable secondaries count and sustaining read operations upon secondary-primary disconnections, and it provides new hybrid disaster recovery and backup solutions with Microsoft Azure, enabling customers to use existing skills with the on-premises version of SQL Server to take advantage of Microsoft's global datacenters.
In addition, it takes advantage of new Windows Server and Windows Server R2 capabilities for database application scalability in a physical or virtual environment. Microsoft provides three versions of SQL Server for downloading: The RTM version is SQL Server is supported on x64 processors only.
It is no longer supported on x86 processors. Microsoft SQL Server is the most recent version available. From Wikipedia, the free encyclopedia. Older version, still supported.

Next SQL Server stop: Archived from the original on Retrieved March 7, Retrieved 17 May The company today launched the first release candidate of SQL Serverwhich will be the first version to run on Windows, Linux and in Docker containers.
The Docker container alone has already seen more than 1 million pulls, so there can be no doubt that there is a lot buy sql server 2008 r2 standard edition 64bit software interest in this new version.
