OR8 is a legacy file format associated with Rational Rose, a software modeling product originally developed by Rational Software and later distributed by IBM.
An OR8 file stores report data for an Oracle8 database model. It is a report-related file rather than the primary project file for the complete Rational Rose model.
Rational Rose Developer for Java was available on multiple platforms. The OR8 format is no longer commonly used by current database modeling software and is mainly encountered in older Rational Rose projects.
Open an OR8 file with the compatible version of Rational Rose that created it, such as Rational Rose Developer for Java. Because the format is associated with an older product, a current general-purpose application may not recognize it.
If Rational Rose is unavailable, a text editor may show limited content, but it will not normally reproduce the database model report.
Open the file in a compatible version of Rational Rose and, where supported, use its report or printing features to create a more portable copy.
