DBDiff 5.0 Description:

DBDiff is a powerful ODBC database utility which performs a comparison between two databases.
Any database that supports ODBC access can be used. The databases DO NOT have to be of the same type, they don't even need to be on the same machine, as long as they are both accessible from the machine running DBDiff.
DBDiff uses a carefully planned and designed algorithm for performing the quickest, most accurate comparison between the databases; this algorithm allows for multiple levels of comparison to be performed on the databases.
Ver. 5.0 now allows you to compare data by using free form sql select statements, you can also create database snapshots to perform off-line comparisons or track historical changes, and many more new features.

Table Structure Comparison - This level will perform a comparison between all tables of the databases. It will find the tables that are common and perform comparisons between their respective columns to find and report the differences (i.e. which columns are common, which are not and what are their differences). DBDiff can go as deep as the length of a column or can be set to ignore the length as well as ignore some columns that it is already known to the user to be different.

Index Comparison - This level will perform a comparison between all the indexes found on all the tables that are common to the database. Index Comparison will retrieve all the indexes that apply to a particular table and compare them with the corresponding ones on the second database (i.e. DBDiff will report all differences regarding indexes, their types (unique or not unique) as well as each of the columns that the index applies to).

Table Data Comparison - This level will perform a comparison of all tables that are found common (including their columns) between the databases. It uses a heuristic algorithm to place the rows that have differences in a manner that "makes sense" for the user to review. You can set various options to refine the type of comparison you want to perform. You can tell DBDiff to ignore case and/or leading or trailing spaces for each row that is compared.

View Structure Comparison - This level will perform a comparison between all views of the databases. It will find the views that are common and perform comparisons between their respective columns to find and report the differences, i.e. which columns are common, which are not and what are their differences, DBDiff can go as deep as the length of a column, or can be set to ignore the length, as well as ignore some columns that it is already known to the user that they are different.

View Data Comparison - This level will perform a comparison of the data contained in all views that are found common (including their columns) between the databases. It uses a heuristic algorithm to place the rows that have differences in a manner that "makes sense" for the user to review. You can set various different options to refine the type of comparison you want to perform; you can tell DBDiff to ignore case, ignore leading or trailing spaces for each row that is compared.

Procedure Definition Comparison - This level will perform a comparison between all procedures of the databases. It will find the procedures that are common and perform comparisons between their respective parameters to find and report the differences, i.e. which parameters are common, which are not and what are their differences, DBDiff can go as deep as the length of a column, or can be set to ignore the length, as well as ignore some columns that it is already known to the user that they are different.
Important: DBDiff does not compare the source code of the procedures, but only their names and parameters.

In order to make it easy to understand the output of the comparison, DBDiff creates a report that includes all the differences (structural, indexes or data) in a user friendly manner. Also reported is other useful information about the databases and the comparison.
DBDiff can also generate an Executive Summary with summary information about a compare.
