ODBC
 ODBC = Open Database Connectivity
 Microsoft supplies a generic middleman
driver with Windows
 Vendors supply drivers for their specific
database or data source
 This enables Access to link to data in almost
any kind of database including Oracle, MS
SQL Server, DB2, MySQL, etc.

Linking to ODBC tables
 3 scenarios



The ODBC connection (DSN or Data Source
Name) exists already (perhaps provided by IT
group)
Create the DSN in advance via Windows
Create the DSN connection while going
through the link table procedure

Create New Windows DSN
(Scenario 2)
 As stated before DSN typically created well in
advance by IT
 But…for illustration purposes we will create it
ourselves
 This scenario thus has two major steps


1 – create the DSN under Windows
2 – Launch the link tables dialogue in Access
and proceed. We have already done this, so
this will not be repeated here
