We wouldn’t want touse these services gratuitously if consumingTDS directly is possible; usingTDS instead of XML is always going tobe more efficient. But for situations inwhich we want to make SQL Serveravailable to non-Microsoft clients,combining SQL, XML, and SOAP maybe an easy way to achieve interoperability.When using .NET clients, thisgives us the ability to permit controlledaccess to our SQL Server withoutrequiring either direct access orwriting an ASP.NET Web service application.A Web service allows directprogrammatic access.Advertiser IndexADVERTISER URL PHONE PGAltova www.altova.com 978.816.1600 4Crystal Decisions www.crystaldecisions.com/cr9/021/ 888.333.6007 27DataDirect www.datadirect-technologies.com/net 800.876.3101 13Gartner www.gartner.com/us/eai 800.778.1997 19Infragistics, Inc. www.infragistics.com 800.231.8588 2, 3Interland www.interland.com 800.845.8706 28/n software inc. www.nsoftware.com 919.402.0590 15Rational Software www.rational.com/offer/webservices13 800.728.1212 11SERVERDESKTOPEVERYWHERENext TimeSince .NET has been released,a plethora of .NET data providershave also hit the market.
