           Summary: Kivio needs a stencil set for Entity Relationship
                    Diagrams
           Product: kivio
           Version: 1.0
          Platform: SuSE RPMs
        OS/Version: Linux
            Status: NEW
          Severity: wishlist
          Priority: NOR
         Component: general
        AssignedTo: psn@linux.se
        ReportedBy: kalle@kde.org


Version:           1.0 (using KDE KDE 3.1.1)
Installed from:    SuSE RPMs
Compiler:          gcc 3.3 
OS:          Linux

Editing UML with kivio is cool (and somewhat more intuitive than in Umbrello, which on the other hand is more powerful), but what I am lacking is a stencil set for Entity Relationship diagrams for database design. In the most basic form, the following would suffice:

- one stencil for entities (a rectangle); it should be possible to add attributes that are displayed in the stencil (some types of ERDs also use "bubbles" to display the attributes; I find that somewhat non-intuitive)
- a labelled connector that has predefined (1, m, n) labels at the ends and a custom label alongside it

If you want to display the design of normalized databases, you would also need pseudo-entities that only exist in order to implement n:m relationships; a diamond is usually used for these.
