Pro Entity Relationship Digramming for nearly any JDBC-compliant database

Pro Has a GUI option available
SchemaSpy is a CLI tool. For people who prefer GUI-based tools there's one available from a different maintainer which stands on top of the CLI version.
Cons
Con Data export
Data export does an individual insert per row of data, which is a little inefficient.
Con Does not work with schema dumpfiles
SchemaSpy has no methods for dealing with when you only have a schema generated via something like (mysqldump --no-data [options] >schema-only_dump.sql
) , and do not currently have access to a live database to connect with.
Con GUI option is a separate download by a different maintainer
Since the GUI version is from a different maintainer, it may be abandoned and eventually break if SchemaSpy development continues beyond that. Or it may implement new features much later than the CLI version.
Con Project may be dead or dying
The codebase on sourceforge hasn't seen an update since 2010.
