AgileJ StructureViews is an Eclipse plugin that generates highly configurable reverse engineered class diagrams for Java programmers. It specializes in supporting agile project development through the automated production of high presentation quality class diagrams with project-specific content generated and regenerated with minimal user effort.
UMLGraph facilitates the declarative specification and drawing of UML class and sequence diagrams. One can specify a class design using the Java syntax complemented by Javadoc tags. Running the UmlGraph doclet on the specification generates a Graphviz diagram specification that can be automatically processed to create Postscript, GIF, SVG, JPEG, fig, or Framemaker drawings. Similarly, sequence diagrams are specified using declarative pic macros and compiled with the GNU plotutils pic2plot program into a PNG, PNM, (pseudo) GIF, SVG, AI, Postscript, CGM, FIG, PCL, HPGL, Regis, or TEK drawing.
ERDesignerNG is a Java-based entity relationship design and database modeling tool. It has a powerful WYSIWYG interface for physical database design, supports 2D and 3D database modeling, browsing, and design, handles tables, relations, indexes, and comments, supports a central repository for all models (Model Repository), supports subject areas, supports domains, supports MySQL, Oracle, Microsoft SQLServer, PostgreSQL, and H2, creates the SQL DDL statements for schema creation, has an integrated schema version control system, can generate schema migration scripts for every change, stores the database definition as XML files for further processing, can export the database schema as GIF, BMP, JPEG, or SVG files, has an integrated reverse engineering module for existing schemas, has a build in schema compare feature, can generate schema documentation as PDF, HTML, RTF, and other formats, and supports schema conversion between different dialects.
DatabaseToUML reverse engineers a database schema from an existing relational JDBC database. Tables and fields are reversed to classes and attributes, constraints are reversed to association, and tables composed only of foreign keys are converted to many-to-many associations. The main idea is to reuse the reversed model in a generator, taking UML2.x (EMF XMI 2.0/2.1) models as input.
