load file format for hierarchical data stores?

by B McDonal » Wed, 07 Feb 2001 04:53:37

Hi. Can someone tell me if there is a standard loadfile format for
representing text data that is to be imported into a hierarchical database?
You know, one that a script would process and that would have the
parent-child relationships hard-coded in the format of the load file?

Something like:

Thanks.

1. Storing hierarchical data in a RDBMS

Can somone point me to information regarding the storage of hierarchical
data in a RDBMS? For example, the storage of a hierarchical product
description data or bill of materials data.

Without special techniques this type of data requires the use of
recursive navigation of the data. This type of navigation is slow and
hard to do with a RDBMS. A special technique, we are researching,
involves creating index tables. However these index tables have the
potential of being quite large. We are interested in finding
information about other possible approaches.
