General

You can then use these database tools to:

• Export data from a database table to a sequential bdbpre file.
• Create a database table from a sequential file or append data to an existing database table bdbpost.
• Reconfigure a database table according to a new data dictionary with bdbreconfig.
• Check or repair the referential integrity in the database with refint.

If changes are made in the data dictionary, for example, if fields are added or field lengths are changed, you can reconfigure the old table to a new one. The data dictionary changes are incorporated in the new table, which also contains the data dictionary table data.

The system you use determines the extension for the executables. For example, bdbpre on Windows is called bdbpre.exe. On UNIX the file is called bdbpre6.2.

The remainder of the document uses the short naming convention, without 6.2 and .exe extension. Some binaries have a slightly different name on Windows, for example:

UNIX name	Windows name
bshell6.2	ntbshell.exe
explode6.2	bic_explode.exe

The term UNIX is used frequently. This term includes various UNIX versions, including Linux if applicable/supported.
