Microsoft SQL Server

Microsoft SQL Server (MS SQL) to system zarządzania bazą danych, wspierany i rozpowszechniany przez korporację Microsoft. Jest to główny produkt bazodanowy tej firmy, który charakteryzuje się tym, iż jako język zapytań używany jest przede wszystkim Transact-SQL, który stanowi rozwinięcie standardu ANSI/ISO.

MS SQL Server jest platformą bazodanową typu klient-serwer. W stosunku do Microsoft Jet, który stosowany jest w programie MS Access, odznacza się lepszą wydajnością, niezawodnością i skalowalnością. Przede wszystkim są tu zaimplementowane wszelkie mechanizmy wpływające na bezpieczeństwo operacji (m.in. procedury wyzwalane).

Darmowe edycje

Poza edycjami czysto komercyjnymi Microsoft udostępnia również edycje darmowe do dowolnego zastosowania (w tym komercyjnego). Edycje te mają różnorodne ograniczenia i tak np. do wersji 2000 (8.0) włącznie nie były m.in. udostępniane graficzne narzędzia do zarządzania bazami danych oraz były ograniczenia co do możliwej ilości połączeń do bazy.

Począwszy od wersji 2005 (9.0) można pobrać wersję z graficznymi narzędziami i nie ma już limitu połączeń. Narzędzia posiadają jednak ograniczone możliwości w stosunku do pełnej wersji, a nawet jedna z istotnych usług dostępnych wcześniej w darmowych wersjach, nie jest już dostępna. Nie można już przez to wykonywać zautomatyzowanych zadań np. archiwizacji baz danych o zadanej godzinie. Dodatkowo ograniczona została również wydajność samego serwera SQL (ograniczono wykorzystywaną pamięć RAM).

Overview

Microsoft SQL Server is a relational database management system (RDBMS) produced by Microsoft. Its primary query language is Transact-SQL, an implementation of the ANSI/ISO standard Structured Query Language (SQL) used by both Microsoft and Sybase. SQL Server is commonly used by businesses for small- to medium-sized databases, but the past five years have seen greater adoption of the product for larger enterprise databases.

The code base for Microsoft SQL Server (prior to version 7.0) originated in Sybase SQL Server, and was Microsoft's entry to the enterprise-level database market, competing against Oracle, IBM, and, later, Sybase itself. Microsoft, Sybase and Ashton-Tate originally teamed up to create and market the first version named SQL Server 1.0 for OS/2 (about 1989) which was essentially the same as Sybase SQL Server 3.0 on Unix, VMS, etc. Microsoft SQL Server 4.2 was shipped around 1992 (available bundled with Microsoft OS/2 version 1.3). Later Microsoft SQL Server 4.21 for Windows NT was released at the same time as Windows NT 3.1. Microsoft SQL Server v6.0 was the first version of SQL Server that was architected for NT and did not include any direction from Sybase.

About the time Windows NT was coming out, however, Sybase and Microsoft parted ways and pursued their own design and marketing schemes. Microsoft negotiated exclusive rights to all versions of SQL Server written for Microsoft operating systems. Later, 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.

Since parting ways, several revisions have been done independently. SQL Server 7.0 was the first true GUI based database server and was a rewrite away from the legacy Sybase code. A variant of SQL Server 2000 was the first commercial database for the Intel IA64 architecture. During this time there was a rivalry between Microsoft and Oracle for winning over the enterprise market.

The current version, Microsoft SQL Server 2005, was released in November of 2005. The launch took place alongside Visual Studio 2005. The SQL Server 2005 Express Edition is currently available for free download. The Microsoft SQL Server product is not just a database; it also contains (as part of the product) an enterprise ETL tool (SQL Server Integration Services or SSIS), a Reporting Server, an OLAP implementation, and several messaging technologies, specifically Service Broker and Notification Services.
