Pull Documents From ORACLE database to SharePoint

Hi,

I have SharePoint 2010 installed on SQL Server 2008.

I have some applications stores data on ORACLE database... I need to show this data in to SharePoint , Don't know List, Document Library,....

This data contains documents stored into the ORACLE database and I need to show it and give the users ability to download them along with other data...

Does SharePoint provide this using Secure Store Service? Or I have to buy a third party product ? I foud one called : Layer2, here is the link :
