Database Browser Portable -- not usable without (Oracle/SQLServer/whatever) client
Just downloaded Database Browser Portable, intending to replace DbVisualizer. Tried to connect to an Oracle database, was told that the Oracle Client was not properly installed. Went to the publisher's site (https://www.etl-tools.com) and eventually found that the tool requires that a client must be installed, for the database system you want to use. Database Browser uses the client's drivers to connect to the database.
