For SQL Server and SQL Server , automatic updates during setup are recommended. Important If you use a merged slipstream, that version of the slipstream must remain available in its original location as long as the instance of SQL Server exists. Detailed history Genesis. On June 12th , Microsoft joined Ashton-Tate was fighting for their desktop product dBASE while Sybase created a variant of Sybase SQL Server for IBM OS/2 (then developed jointly with Microsoft), which was released the following year. This was the first version of Microsoft SQL Server, and served as Microsoft’s entry to the enterprise-level . Aug 05,  · All frameworks with major version 4 do an in-place upgrade, and they are backward compatible. For more information, check Framework | Free official downloads (). SQL Server and SQL Server Framework SP1, which is supported till , so this retirement doesn’t impact them. Network Software.

If you perform a new installation, the correct dependency permissions are set on the physical disks that have an associated drive letter and on the mount points. The dependency permissions are set automatically during setup. This includes the cumulative update and the required service pack. Important If you use a merged slipstream, that version of the slipstream must remain available in its original location as long as the instance of SQL Server exists. Additionally, you must set the correct dependencies in installations that are missing the required dependencies.

If only the root physical disks dependency is added and the mount points dependency is not added, database corruption will occur on failover. Database corruption may also occur during a SQL Server restart should disk resources go offline and return to online state even without failing over. Warning If you previously installed SQL Server to a root directory, you may be unable to install service packs or cumulative updates.

Cluster Shared Volumes. Create a dependency in the mounted volume disk resource that specifies the disk that is hosting the mount point folder. This makes the mounted volume dependent on the host volume, and it makes sure that the host volume comes online first. Note In Windows Server and later versions of Windows, this practice is no longer necessary.

If you move a mount point from one shared disk to another shared disk, make sure that the shared disks are located in the same group.

Try to use the root host volume exclusively for mount points. The root volume is the volume that hosts the mount points. This practice greatly reduces the time that is required to restore access to the mounted volumes if you have to run the Chkdsk. Featured SQL Server resources. Download the e-book. Get the kit.

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. NET Framework. SQL Server introduced DMVs Dynamic Management Views , which 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 objects , but they are generic bitstreams. Intrinsic awareness of 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.
