I’ve heard it said that Katmai (SQL Server 2008) is the second step of a two step release. In the same way that SQL Server 2000 was a part-two to SQL Server 7, some think that SQL Server 2008 is a part two to SQL Server 2005.
At first this thought made sense, because SQL Server 2008 is an evolution of the SQL Server 2005 engine, the same way the SQL Server 2000 built on the SQL Server 7 engine.
Now I’m not so sure.
Think about the key new technologies in SQL Server 2008: Policy Based Management, Performance Data Warehouse, PowerShell, Data Compression. None of these technologies existed in SQL Server 2005 RTM.
And think of the SQL Server 2005 new technologies that are being extended in SQL Server 2005. The most talked about new technology in SQL Server 2005 was CLR. Hear much about CLR in SQL Server 2008? Service Broker has some enhancements. But HTTP endpoints and Notification Services are actually English Queried right out of SQL Server 2008. Hmmm. I guess they should have been on the SQL Server 2005 deprecation list.
No, SQL Server 2008 isn’t a SQL Server 2005 sequel. SQL Server 2008 is a fresh new vision for SQL Server. SQL Server 2008 the first punch of a two punch set up focused squarely at managing the enterprise level database. SQL Server 2008 is a down payment on the big gains in SQL Server 11.
I think The SQL Server PMs nailed it and this the the best right direction possible.
