Database Comparer ActiveX for ASP, VBScript, JavaScript helps you compare one database with another or a database with a DDL/SQL script or even two DDL/SQL scripts. It takes a Target database or Target SQL/DDL script and compares it to a Master database or Master SQL/DDL script. It locates all structure differences and prepares a SQL script which can be applied to the Target to make its structure equal to the Master. It extracts all objects, descriptions and links from both Master and Target and then compares actual objects.
