Chapter 4: Importing Data

•
ReplaceDatabase
, which replaces the database information in the current MasterDirectory file
with the information from the source file.
•
Synchronize
, which compares the information in the mapped fields from the source file with the
database information in the current MasterDirectory file. This option adds the new records and
updates any existing records that have changed (like the AppendUpdate option) and also deletes
data from the current MasterDirectory file if the data are not in the source file.
•
Compare
, which compares the information in the mapped fields from the source file with the
database information in the current MasterDirectory file. When you choose this option, no new
destination file is created. However, MasterDirectory does generate a report in the comma
delimited fields format, which shows the new and updated records between the source file and the
current MasterDirectory file. This report file has the title of the map with a “.cmp” extension and is
located in the directory where the map file resides. You should select this option if you want to
know the changes between the information in the mapped fields from the source file with the
database information in the current MasterDirectory file.
14. If you selected one of the following Import Mode options, you must specify the Key field in the Key
Field box:
•
AppendNew
•
Update
•
AppendUpdate
•
Delete
•
Synchronize
•
Compare
The Key field is a field that you have already set as an index in MasterDirectory. (Refer to "Creating
Indexes" in Chapter 3.) MasterDirectory uses this field to match records from the imported source
file(s) to records in the current directory. The Key Field box contains all index fields that were mapped.
NOTE:
Index fields that were not mapped will not appear in the Key Field box.
15. Choose the
Advanced
button.
The Advanced Settings For Import dialog box appears.
