Basic Configuration Entries Local & Client Configuration
  The following fields appear when the driver setup dialogue is initially displayed:
Data Source Name: Name (DSN) that other applications will use to access the database. Case-insensitive, maximum length is 32 characters. With regards to the ProvideX ODBC driver, the DSN can be considered the logical name of the database. The following characters are not permitted in a DSN:

[ ] {}( ) , ; ? * = ! @ \
Description: Optional free form remark describing the Data Source Name. Maximum length is 127 characters.
Database Directory: Location of the ProvideX Data Dictionary file (providex.ddf) which is the relative starting point for all embedded file references. Maximum length is 127 characters. If used with Sage MAS 90 or Sage MAS 200, then the directory must contain the DDICT directory.

If providex.ddf is found in this directory, then all file/table definitions contained in it are made available to the ODBC driver. Using the embedded data dictionary simplifies the installation and maintenance issues regarding the ODBC driver.

The providex.ddffile located in the database directory can be set up to contain only a subset of the files used by an application. This can be used to control which files/tables are presented to the end-user. In order to provide different "views" of the database, create separate directories, each containing a different providex.ddf file.

Note that the providex.dde file is not required by the ODBC driver. For more information, see ProvideX Data Dictionary.

Definition File: Path and name of the INI file used to define the data dictionary manually for files that cannot be handled by the ProvideX embedded data dictionary. Maximum length is 127 characters.

For more information, see INI Definition.
