Link between SAP Ztables and MS-ACCESS database via XI

Hi All,

I have two application one is in Ms-Access and other is in SAP . I have to link the SAP ztables to the MS-Access databse, is this be done with via XI. If yes, do i need to write the interface programs while fetching the data from the XI to SAP, or XI will take care of the updation and linking between the SAP and access application , since the cross flow of data between two application will be there .
