Delta Snap is a database schema snapshot tool that takes a copy of a database schema and saves the details into an XML file. Delta Snap can take a snapshot of SQ Server, Oracle and MySQL databases.
SQL Delta and SQL DXP can use a snapshot in a schema compare to compare an offline schema with an online schema. A snapshot cannot be directly updated however a script can be generated for update.
This allows a remote database schema to be compared by using a snapshot, an update script generated and then the update script can be applied to the remote database.
Delta Snap can run using the GUI or as a command line application. However by running using the command line Delta Snap can be automated to create snapshots of various databases on a timed basis. Delta Snap also has emailing capability so a snapshot could be emailed to someone once taken.
