I'm searching for a tool to dump a database including DDL and content as plain SQL-Sсript, so that it can be archived in a plain text format. I know e.g. the Oracle dump tools or MySQL dump, but is there a tool which can connect to different data sources and get the job done? GUI would be great.
Check out http://squirrel-sql.sourceforge.net/. Gui, cross-platform and supports any database with jdbc driver.
Look at set of SSMA Microsft's free tools (Oracle, Sybase, MySQL..) http://www.microsoft.com/sqlserver/2005/en/us/Migration-oracle.aspx
