Before you can access external databases from the program, you must configure them using the Microsoft ® external ODBC and OLE DB programs.
Once you have configured your databases, you can access their data from the program, even if you do not have the database system that created the data installed on your system. You can access data from the following applications:
Once you have successfully configured a database to use with the program, a configuration file with the extension UDL is created. This configuration file contains the information the program needs to access the configured database. By default, UDL files are stored in the Data Links folder. You can specify a different location for UDL files from the Options dialog box.
The following topics demonstrate how to set up a data source using ODBC, and how to configure data sources so that you can use them with the program. For detailed information about ODBC and OLE DB, refer to the following online Microsoft resources:
Several database management systems supported, have direct drivers available for OLE DB. If you use these direct drivers, you do not need to set up configuration files from within both ODBC and OLE DB; you only need a single OLE DB configuration file.
Direct database drivers are available for the following database systems:
ODBC is an intermediary program that makes data from one application available to other applications.
You can use OLE DB to establish a UDL configuration file that points to an external database table.
If you are using the 64-bit release of the product and DbConnect with a connection that accesses a Microsoft Access database or a Microsoft Excel spreadsheet using one of the two following methods, you need to change your connections to use Microsoft SQL Server. Microsoft does not support a 64-bit version of these technologies.
Microsoft SQL Server comes in three different editions. If you are accessing data from an MDB or XLS file today, you might find that using Microsoft SQL Server Express Edition is adequate for your needs. Microsoft also offers Standard and Enterprise editions of SQL Server.
