Mydbdiff

Utility: mydbdiff

Synopsis: Compare two database schema's using diff or sdiff

Author: Art S. Kagel

Revision: 1.3

Comments: Requires myschema Features Version 6.25 or later (included here).
	Mydbdiff is a ksh script that takes advantage of an feature of myschema
	(-o) to acquire a schema of each database with objects ordered to ease
	comparison.  While the myschema -o option should not be use to create a
	schema file for porting (as you may not be able to execute such a schema
	because dependencies may not be created in the correct order) a saved
	schema created this way can be compared to the active database schema
	to determine changes over time using the -f option.

Release Notes:
	Releases 1.2 & 1.3 add new features.  The new -d option allows one to
	specify any diff utility.  The -S option allows one to specify that one
	or both of the comparative schemas be saved in a file in the current
	directory named <database>.mydbdiff.  The -f option allows one to
	compare a live database's schema to a comparative schema previously
	saved using the -f option or manually generated using myschema -o.  The
	combination of -S and -f allow for tracking changes to a single
	database over time.
