RE: Migrating from MS Access to oracle

Jeff

   If it is just a few users, why not continue to use Access as a front-end to Oracle? Past that, as Roy suggests visit with your Web developer and ask which are the supported tools at your site. If he shrugs and says "whatever you want to use", then take this as a harbinger of DBA troubles to come.

My concern with migrating from MS Access to oracle isn't with moving the data but what tool am I going to use to build the application which accesses the data. We have several Access applications that I would love to move to our intranet. I just don't know where to begin, all we have for a web developer is a guy right out of college. I would appreciate it if someone could share with me what has been done elsewhere. Has anyone gone from using client-side applications to using web-based applications? What development tools/languages did you decide to use and why?

Thanks,
Jeff

I don't know if this is the cleanest way to do what you want but here goes:

1. Save/export Access table into MS Excel.
2. Use the transpose function to convert columns to rows.
3. Clean up new column names
4. Save as .csv (comma delimited file)
5. Create table(s) in Oracle
6. Create sql loader script based to load into table.

I've used this approach before with sucess. It spared me from having to write code to do the transposing. If you need to do some extra validation/conversion you could set up a staging table to load into, then apply validation logic with PL/SQL procedures functions to load into final table. Hope it helps
