Using ruby to transfer and clean data between databases

Richard Dowden

10/24/2007 12:12:00 PM

Hi all,

I have some data in an access database and I want to move this to my new
SqlServer2005 database. However the schema of the database has changed
significantly, it's been normalised and various tables have been added,
so the data won't fit in exactly without first being 'cleaned' so to
speak.

I was just wondering whether you think I could write some kind of ruby
script to automate some of it, whether anyone has done something
similar, or if there's a better way of doing this.

Fairly open question I know, but I want to know how others would go
about doing this before I embark upon it.

Cheers,
Daf

I was going to write the same. Additional info: DTS allows you to do
arbitrary transformations using a scripting language. Last time I
looked JavaScript and VisualBasic were supported. Since this is
integrated into DTS I'd say this is probably a better choice.

Kind regards

Ok, I think i'll be looking into doing that then. I believe DTS is
called 'Integration Services' in SQL server 2005 correct? I think I'll
need to install it off the cd as I can't find it in it's start group.

Thanks for the help.

Try Business Intelligence Development Studio :-)
Integration Services (SSIS) is designed in Visual Studio like BIDS (Business
Intelligence Development Studio) unlike DTS which can be done in Enterprise
Manager of SQL Server 2000.

Anyway you would be better served in
