          • Add basic fields to UML/database diagram

            You are missing some very basic field types (for UML and database):

            ENUM - enumerated field
            EPOCH - Unix timefield
            BLOB - blob field

            In addition, allow us to select SHORTHAND NAMES for fields:

            CHAR instead of "Character"
            INT instead of "Integer"
            BIGINT.... etc.

            Or better yet, allow us to create our own sets of drop-down fields. As it now stands, the names you use are not compatible with certain database products, which means they need to be re-edited after importing elsewhere.

            • Identifying PK and FK in Classes

              It would be nice to identify the PK and FK with visual icons as simple of PK or FK.

                • auto incrementation

                  Hello, my idea is to share the possibility to auto increment a variable like your primary key for example for id's. I search this option but I never saw it in this website.

                  It's few line of codes to do it... all is already here for do it ^^.

                  Thank you and see you !

                    • Off Page Connectors

                      Simple 'off-page connectors' would go a long way toward cleaning up complex database schema.

                      The ability to 'hide' relationships helps in this matter, but this makes it easy to inadvertently forget about the relationship.

                        • Allow VARCHARS and NVARCHARS to be able to be MAX size

                          For database schemas there should be the ability to set the size of a VARCHAR (or NVARCHAR) column to MAX. Otherwise, when modeling we need to know the exact limitation of the datatype for whatever database we are working in.

                              • Store sample data for datamodel

                                It would be great if I could add some sample data to the schema I am generating. That way when I run the generated .DDL it will generate some sample data in the database for me to test against.

                                This is one of the only feature stopping me from adopting this as my primary tool.

                                  • New Idea: add the ability to manually route reference lines between tables

                                    I think that the connection lines between tables could be routed with more flexibility and not restricted to begin in the FK and end in the PK, neither in the left/right side of the diagram.

                                    I understand and I like the way GMM manage the FK-PK relationship between tables, indeed when a single column "becomes" a FK (after both tables has been related) the icon near the column marks clearly this fact, and if I select the relation I can see the participants and roles... IMHO this visual and textual information is enough (may be not to other people...) and…
