You can connect to an Access file in OpenOffice.org. Choose File > New > Database, choose to connect to an existing database, choose Access as the format, and click Next.
In the next window, specify the location of the Access database and follow the wizard through the rest of the windows. Save the database. The name you use will show up in lists of databases, so you can get to the data in the Access database.
Alternately, if you want the data in Access to be in a true OpenOffice.org Base database, then follow the instructions in this article.
