Connecting two databases

  • I am in the process of creating a data warehouse (SS 2005)that updates a large chunk of data nightly from another SQL database (ss 2000) on a different server. The ss2000 box is being used by a 3rd party application.

    Two Questions:

    1 - What would be best method of pulling data from the ss2000 box?

    Note: the data would be pulled nightly and would include all data for active projects.

    Link the databases/dts package/?

    2 - What would be the suggested method for setting up the access account from the SS2005 to SS2000?

    all help appreciated

  • depending on the amount of data you'd expect ....

    - you could setup replication to your needs and sync nightly

    - you could use the tablediff.exe (check books online).

            this ms-util generates insert/update/delete-statements

    - 3-th party tools (e.g. redgate sqldatacompare, dbghost ...)

  • Again dependant on the data volume; we tend to use DTS to flatfile, remote tools (Connect Direct in our case) to move the file and then DTS (or SQLLDR is Oracle) to load.

    Because we are moving files between DBMS's, and data volume can be significant, flat-file is our preferred option but it may not be best for you.

  • In this version you want to use Integration Services to haul your data over and into your warehouse.
