Longhorn, Vista to drop SQL Server 2000 and MSDE support
In
a surprise move, Microsoft announced that the soon-to-be released Microsoft
Windows Vista operating system and Microsoft Windows Server "Longhorn" will
not support earlier versions of SQL Server, including SQL Server 2000 (all
editions including MSDE), SQL Server 7.0, and SQL Server 6.5.
SQL Server 2000
Customers running applications with these earlier versions of SQL Server
should consider evaluating and upgrading to SQL Server 2005, which was designed
to take advantage of the upcoming security and performance enhancements
in the operating environment. Visit
http://www.microsoft.com/sql/howtobuy/sqlonvista.mspx to learn more
about Microsoft's announcement.
Among the things that you need to consider before upgrading is
minimum system requirement. Hardware requirements for SQL Server 2005
are higher than those of SQL Server 2000. Also, SQL Server 2005 requires
the .NET Framework 2.0. In terms of features, SQL Server 2005 provides a
superior set of features over SQL Server 2000 including database
mirroring, CLR integration, database snapshots, encryption, and enhanced
XML support.
MSDE
The impact on MSDE users will be greater on Vista since MSDE is a
desktop engine. Users of MSDE should consider upgrading to SQL Server 2005 Express,
which is the free version of the Microsoft SQL Server
2005 database. SQL Server 2005 Express is built on the same core database engine as
the other editions of the SQL Server 2005 product line. It has the same
essential data types and programmatic features as the other editions of
SQL Server 2005, giving it some important advantages over MSDE. SQL Server 2005 Express runs on the same hardware as MSDE. Recommended
system requirements are as follows:
- Processor — A minimum of a 600-MHz processor is required and a 1-GHz
processor is recommended.
- RAM — A minimum of 256 MB of RAM is required and 512 MB of RAM is
recommended.
- Disk Space — A minimum of 170 MB of free disk space is required, with
the Microsoft .NET Framework V2.0 as a prerequisite.
MSDE vs. SQL Server 2005 Express
Although SQL Server Express has a number of new features, some MSDE
features are no longer included in the new Express edition of SQL Server
2005. The following table provides a comparison of MSDE and SQL Server
2005 Express:
