What is dB2dB?



dB2dB is a utility program written in Visual Basic that allows
for quick and easy transformations of database record
information from one database to another.  Any field in one

database can be linked to another field in a second database for
the purposes of data transfer.



How do you use dB2dB?



Select your source database using the dB1 button.  A file box
will appear that shows only files with a .dbf extension.  Select
a database file and click on OK.  A window will appear with
information on the selected database.  Repeat for your target
database using the dB2 button.  A window will again appear with
information on the selected database.  Full paths to the
selected databases appear above each dB button.  These fields
are not editable.



Click on the list box for dB1 of the field where you have source
information you wish to transfer to dB2.  Directly below the box
information about the selected field will appear.  This
information tells you the type of field and the length of the
field.  Types of fields are C for character, N for numeric, D
for date, M for memo, L for logical,.  dB2dB will only convert
like fields.  If the source field is a date field, the target
field must be a date field.  Also because of the varying memo
field types, dB2dB will not link to or from any memo field.  Any
attempt to do so will cause a box to be displayed notifying you
that linking of memo fields is not allowed.  Click on the list
box for dB2 of the field you wish to link with the selected
field of dB1.  Click on the Link button and a link will appear
in the Link list box.  Continue selecting fields in dB1 to be
linked with fields in dB2.  If you change your mind about a
link, delink by clicking on the link information in the Link
list and click on Remove Link.  This will remove your link. 



After all links have been selected, click on GO.  A window will
appear asking if you wish to erase the target database first if
it contains any previous records.  Clicking on yes erases all
previous records, clicking on no adds information to the target
database.  If you click on yes to erase the previous information
it is gone forever.  Please be sure this is what you really want
to do!  A second window will appear informing you that the
erased data will be lost forever and confirmation that this is
really what you want to do.



The cursor will change to an hourglass as the information is
transferred between the databases.  The amount of time this
takes will depend upon the CPU speed, hard disk speed, and the
size of the databases.  However, it is quite fast and on slow
CPU's with small (under 1000 records) databases should take less
than 2 minutes.  On fast CPU's with small (under 1000 records)
databases it should take less than 10 seconds.  On a 486-33 with
16mS hard drives transferring 610 records with 57 fields took 6
seconds.
