==Detailed history==
===Genesis===
By the late 1980s [[Microsoft]] was interested in the low end of the [[database software]] market, while [[Sybase]] focused on the [[Fortune 1000]]. After the former discussed a partnership with Sybase rival [[Informix Corporation]],<ref name="rdbmsingressybase20070613">{{Cite interview|interviewer=Doug Jerger|title=RDBMS Workshop: Ingres and Sybase|url=https://archive.computerhistory.org/resources/access/text/2013/05/102702565-05-01-acc.pdf|access-date=2025-05-30|publisher=Computer History Museum|date=2007-06-13}}</ref> in January 1988 Microsoft joined [[Ashton-Tate]] and Sybase to create a variant of [[Sybase SQL Server]] for [[IBM]] [[OS/2]] (then developed jointly with Microsoft) compatible with Ashton-Tate's [[dBASE]] software. [[Information Builders]], [[Borland]], and [[Symantec Corporation]] announced support for the product. Microsoft's [[Bill Gates]] praised Sybase as the best SQL database engine, and persuaded Ashton-Tate to use it instead of its own. Rivals such as [[Microrim]] ([[R:Base]]), [[Novell]], [[Oracle Corporation]], and [[Lotus Development]] said that they would use their own technology, or that they expected IBM's own SQL technology in OS/2 Extended Edition to be the standard.{{r|mace19880118}}
Scheduled for the second half of 1988,<ref name="mace19880118">{{Cite magazine|last=Mace|first=Scott|date=18 January 1988|title=Ashton-Tate, Microsoft Join Forces To Introduce SQL Database Server|url=https://books.google.com/books?id=Dz8EAAAAMBAJ&pg=PA1|access-date=2025-05-25|magazine=[[InfoWorld]]|pages=1,8|volume=10|issue=3}}</ref> it was released in 1989.<ref>{{cite book|last=Harris|first=Scott|author2=Curtis Preston|title=Backup & Recovery: Inexpensive Backup Solutions for Open Systems|url=https://books.google.com/books?id=M9mbAgAAQBAJ&q=origins+of+SQL+Server+Sybase&pg=PA562|year=2007|publisher=O'Reilly|isbn=978-0596102463|page=562}}</ref> This was the first version of Microsoft SQL Server, and served as Microsoft's entry to the enterprise-level database market, competing against Oracle, IBM, Informix, Ingres and later, Sybase. SQL Server 4.2 was shipped in 1992, bundled with OS/2 version 1.3, followed by version 4.21 for [[Windows NT]], released alongside Windows NT 3.1. SQL Server 6.0 was the first version designed for NT, and did not include any direction from Sybase.
Sybase revenue grew quickly during the late 1980s from the Microsoft relationship.{{r|rdbmsingressybase20070613}} About the time [[Windows NT]] was released in July 1993, Sybase 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. (In 1996 Sybase changed the name of its product to [[Adaptive Server Enterprise]] to avoid confusion with Microsoft SQL Server.) Until 1994, Microsoft's SQL Server carried three Sybase copyright notices as an indication of its origin.
===SQL Server 7.0===
[[File:Microsoft_SQL_Server_7.0_Setup_Splash_Screen.jpg|thumb|right|SQL Server 7.0 Splash Screen]]
After problems at its main rivals, SQL Server became Oracle's most important competitor.<ref name="rdbmslateryears20070612">{{Cite interview|interviewer=Burton Grad|title=RDBMS Plenary Session: The Later Years|url=https://archive.computerhistory.org/resources/access/text/2013/05/102701921-05-01-acc.pdf|access-date=2025-05-30|publisher=Computer History Museum|date=2007-06-12}}</ref> SQL Server 7.0 was a major rewrite (using C++) of the older Sybase engine, which was coded in C. Data pages were enlarged from 2k bytes to 8k bytes. Extents thereby grew from 16k bytes to 64k bytes. User Mode Scheduling (UMS) was introduced to handle SQL Server threads better than Windows preemptive multi-threading, also adding support for fibers (lightweight threads, introduced in NT 4.0, which are used to avoid context switching<ref>{{cite web|url=https://technet.microsoft.com/en-us/library/aa175393%28v=sql.80%29.aspx|title=Developer tools, technical documentation and coding examples}}</ref>). SQL Server 7.0 also introduced a multi-dimensional database product called SQL OLAP Services (which became Analysis Services in SQL Server 2000).
SQL Server 7.0 would be the last version to run on the DEC Alpha platform. Although there were pre-release versions of SQL 2000 (as well as Windows 2000) compiled for Alpha, these were canceled and were never commercially released. Mainstream support ended on December 31, 2005, and extended support ended on January 11, 2011.
===SQL Server 2000===
SQL Server 2000 included more modifications and extensions to the Sybase code base, adding support for the [[IA-64]] architecture (now out of "mainstream" support<ref>{{cite web|url=http://www.computerworld.com/article/2516742/computer-hardware/microsoft-ending-support-for-itanium.html|title=Microsoft ending support for Itanium|date=April 4, 2010}}</ref>). By SQL Server 2005 the legacy Sybase code had been completely rewritten.<ref name="Scriptcase">{{cite web
Since the release of SQL Server 2000, advances have been made in performance, the client IDE tools, and several complementary systems that are packaged with SQL Server 2005. These include:
*

SQL Server 2000 also introduced many T-SQL language enhancements, such as table variables, user-defined functions, indexed views, INSTEAD OF triggers, cascading referential constraints and some basic XML support.<ref>{{cite web|url=http://www.informit.com/articles/article.aspx?p=25735|title=What's New in SQL Server 2000 | New SQL Server 2000 Features | InformIT}}</ref><ref>{{cite web|url=http://sqlmag.com/t-sql/sql-server-2000s-coolest-features|title=ITPro Today: IT News, How-Tos, Trends, Case Studies, Career Tips, More}}</ref>
With the release of Service Pack 3, Microsoft also released the first 64-bit version of the SQL Server for the [[Itanium]] IA-64 platform
Mainstream support ended on April 8, 2008, and extended support ended on April 9, 2013.
===SQL Server 2005===
SQL Server 2005 (formerly codenamed "Yukon") was released in November 2005, introducing native support for [[x86-64|x64]] systems and updates to Reporting Services, Analysis Services & Integration Services.<ref name="The Definitive Guide to Scaling Out SQL Server 2005">{{cite book|author=Don Jones|url=https://books.google.com/books?id=MhkaNTEGCdgC&pg=PA218|title=The Definitive Guide to Scaling Out SQL Server 2005 Edition|publisher=realtimepublishers.com|year=2005|isbn=9781931491532}}</ref> It included native support for managing [[XML]] data, in addition to [[relational database|relational data]]. For this purpose, it defined an <code>xml</code> [[data type]] that could be used either as a data type in database columns or as [[Literal (computer science)|literal]]s in queries. XML columns can be associated with [[XSD]] schemas; XML data being stored is verified against the schema. XML data is queried using [[XQuery]]; SQL Server 2005 added some extensions to the [[T-SQL]] language to allow embedding XQuery queries in T-SQL. It also defines a new extension to XQuery, called XML DML, that allows query-based modifications to XML data. SQL Server 2005 also allows a database server to be exposed over [[web service]]s using [[Tabular Data Stream]] (TDS) packets encapsulated within [[SOAP]] requests. When the data is accessed over web services, results are returned as XML.<ref name="Database Engine XML Enhancements">{{cite web|url=http://msdn.microsoft.com/en-us/library/ms170809.aspx|title=Database Engine XML Enhancements|accessdate=December 3, 2007}}</ref>
[[Common Language Runtime]] (CLR) integration was introduced with this version, enabling one to write SQL code as Managed Code by the CLR. For relational data, [[T-SQL]] has been augmented with error handling features (try/catch) and support for recursive queries with CTEs (Common Table Expressions). SQL Server 2005 has also been enhanced with new indexing algorithms, syntax and better error recovery systems. Data pages are [[checksum]]med 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 (computing)|cluster]] is easier. SQL CLR was introduced with SQL Server 2005 to let it integrate with the .NET Framework.<ref name="Database Engine Enhancements">{{cite web|url=http://msdn.microsoft.com/en-us/library/ms170910.aspx|title=Database Engine Enhancements|accessdate=December 3, 2007}}</ref>
SQL Server 2005 introduced:
* [[Multiversion concurrency control|Multi-Version Concurrency Control]] (MVCC); user facing features include new transaction isolation level called SNAPSHOT and a variation of the READ COMMITTED isolation level based on statement-level data snapshots.
* Multiple Active Results Sets (MARS), a method of allowing usage of [[database connection]]s for multiple purposes.<ref name="MARS">[http://msdn.microsoft.com/en-us/library/ms345109(SQL.90).aspx Multiple Active Result Sets (MARS) in SQL Server 2005. retrieved June 20, 2009]</ref>
* DMVs (Dynamic Management Views), 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.<ref name="Dynamic Management Views and Functions">[http://msdn.microsoft.com/en-us/library/ms188754.aspx Dynamic Management Views and Functions. retrieved June 6, 2010]</ref>
Service Pack 1 (SP1) was released on April 18, 2006, adding Database Mirroring, a high availability option that provides redundancy and failover capabilities at the database level<ref name="database mirroring">{{cite web|date=November 20, 2007|title=Issues to consider when you use the database mirroring feature in the initial release of SQL Server 2005|url=http://support.microsoft.com/kb/907741|accessdate=September 4, 2011|publisher=Support.microsoft.com}}</ref> (Database Mirroring was included in the RTM release of SQL Server 2005, but it was not enabled by default, being supported for evaluation purposes{{citation needed|date=June 2015}}). Failover can be manual or automatic; automatic failover requires a witness partner and an operating mode of synchronous (also known as high-safety or full safety).<ref name="Automatic Failover">{{cite web|title=Automatic Failover|url=http://msdn.microsoft.com/en-us/library/ms189590.aspx|accessdate=September 4, 2011|publisher=Msdn.microsoft.com}}</ref> Service Pack 2 released on February 19, 2007, Service Pack 3 was released on December 15, 2008, and SQL Server 2005 Service Pack 4 released on December 13, 2010.
Mainstream support for SQL Server 2005 ended on April 12, 2011, and Extended support for SQL Server 2005 ended on April 12, 2016.
===SQL Server 2008===
SQL Server 2008 (formerly codenamed "Katmai")<ref name="2k8">{{cite web|url=http://www.microsoft.com/sql/prodinfo/futureversion/default.mspx|title=Microsoft SQL Server 2008|website=[[Microsoft]]|accessdate=April 6, 2007}}</ref><ref name="PaulFlessner">{{cite web|title=ChannelWeb: Next SQL Server stop: Katmai|url=http://www.crn.com/storage/170702999|accessdate=November 5, 2005|url-status=dead|archiveurl=https://web.archive.org/web/20070322212538/http://www.crn.com/storage/170702999|archivedate=March 22, 2007}}</ref> was released on August 6, 2008, announced to the SQL Server Special Interest Group at the ESRI 2008 User's Conference on August 6, 2008, by Ed Katibah (Spatial Program Manager at Microsoft), and aims to make data management [[self-tuning]], self organizing, and self maintaining with the development of ''SQL Server Always On'' technologies, to provide near-zero downtime. SQL Server 2008 also includes support for [[structured data|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 [[Binary large object|BLOBs]] (binary large objects), but they are generic bitstreams. Intrinsic awareness of multimedia data will allow specialized functions to be performed on them. According to [[Paul Flessner]], senior Vice President of Server Applications at Microsoft, SQL Server 2008 can be a data storage backend for ''different varieties of data: XML, email, time/calendar, file, document, spatial, etc.'' as well as perform ''search, query, analysis, sharing, and synchronization'' across all data types.<ref name="PaulFlessner"/>

Spatial data will be stored in two types. A "Flat Earth" (GEOMETRY or planar) data type represents geospatial data which has been projected from its native, spherical, coordinate system into a plane. 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".
