Why choose ssis
Why choose SSIS?

  • 64bit support

  • Parallel in-memory multi buffer architecture helps to load data several times faster than DTS.

  • Logging, Configuration, CheckPoint etc.

  • Source Safe Integration because everything is XML

  • Many new Tasks (e.g. Script Task, For Each Loop, XML Task etc.) that replace need for ActiveX

    Less Maintenance… Faster Development… Faster Performance


Dts vs ssis speed test
DTS vs. SSIS Speed Test

  • On 32 bit dual core machine

  • Pulling 1 million rows out and writing to SQL table with no transformation

  • SSIS 65% + faster than DTS

  • Adding transformation would add more SSIS advantage


Project options
