- 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.
