Could someone recommend a db management tool that supports SQLite, MySQL, PostgreSQL, and is web-based? By 'web-based' I just mean it can be run in a browser locally or remotely.
If a remote desktop is an acceptable web-based solution, you could have Navicat Premium on a remote server that way you don't need the tool locally (premium is the cross-databases edition of the tool: it has
SQL Lite and even
SQL Server) .
While not truly web based, you can start the dbWatch interface from a java webstart session. You can test this on our webpage (http://www.dbwatch.com/). It supports Oracle, SQL Server, MySQL, Sybase, PostgreSQL and Ingres. Other platforms will be supported in the future.
I work there, so you know :-) -Chris
