It is possible to retrieve (import) schema from existing database. Like Schemaspy, SchemaCrawler generates database diagrams using Graphviz. Note that SchemaCrawler is not just a diagramming tool but also a database schema discovery and comprehension tool and has powerful scripting ability, using JavaScript, Groovy, Ruby or Python, You can easily filter out tables, views, columns, stored procedure and functions based on regular expressions, using the grep functionality. Schemaball is an SQL database schema viewer. It however requires Perl and a few modules, such as GD and optionally Math::Bezier and SQL::Translator.
Schemaball creates flexible visualizations of database schemas. Schemas may be read from an SQL schema dump, flat file or a live database. Shemaball was originally designed for MySQL and works with MySQL out of the box. While InnoDB tables support foreign keys (as of Mysql 3.23.44), MyISAM tables do not (as of 4.0). Therefore, Schemaball can identify foreign keys using CONSTRAINT table options, by regular expressions applied to participating tables, or by reading constraints from a file.Database design tools make it easy to design database schema, define table structure, specify relationships and constraints.
