Understanding Foreign Tables
Foreign tables are text files, or any other files or tables, that are not recognized by Oracle's JD Edwards EnterpriseOne software. However, they must reside in a database that is supported by JD Edwards EnterpriseOne, such as:
Oracle
Access
IBM i
SQL Server
Before you can work with foreign tables in Oracle's JD Edwards EnterpriseOne Table Conversion Design Aid, you must define the database to JD Edwards EnterpriseOne. This definition is created when you set up an ODBC data source or an Oracle Call Interface (OCI) data source that points to the database where the foreign tables reside.
You must also add a data source in JD Edwards EnterpriseOne that points to the ODBC or OCI data source that you defined. For each ODBC data source, database instance, or library that contains foreign tables, you must set up an environment. The environment points to the JD Edwards EnterpriseOne data source, which in turn points to the database or library. In addition, you must set up an ODBC mapping from the data source to the environment.
