NAME¶

terd - Tool for Entity-Relationship Diagrams

SYNOPSIS¶

terd [options] [diagram]

DESCRIPTION¶

terd is an X11/Motif based graphical editor for drawing entity-relationship diagrams. Diagrams can be loaded from and stored to a file. It can print diagrams to a PostScript printer or save as PostScript to a file.

terd is part of The Toolkit for Conceptual Modeling (TCM).

ARGUMENTS¶

You can call terd with a single diagram name as argument. If this argument is an existing file then terd tries to load a diagram from it. If it does not exist, a new diagram is created with the argument as diagram name. terd files should have suffix '*.erd'.

Without a diagram argument, terd creates a new empty entity-relationship diagram with the name 'untitled.erd'.

In addition to the standard X11 toolkit options (see X11(7)) terd accepts the options listed below:

-drawing widthxheight

Create a drawing area of width pixels wide and height pixels high.

-help

Write all available options to standard output and quit.

-maxdrawing widthxheight

The drawing area can not be larger than width pixels wide and height pixels high.

-priv_cmap

Start the editor with a private colormap.

-projdir directory

Set the project directory (current working directory) to directory.

-toEPS [file.eps]

Generate EPS (to file.eps or stdout when no file name was given) and quit.

-toFig [file.fig] [-latex]

Generate Fig format (to file.fig or stdout when no file name was given and quit. When the -latex option is given, LaTeX fonts are generated, otherwise normal PostScript fonts are generated. The Fig format can be read by xfig(1) and fig2dev(1).

-toPNG file.png

Generate PNG format to file.png and quit.

-toPS [file.ps]

Generate PostScript (to file.ps or stdout when no file name was given) and quit.

-version

Write the TCM version to standard output and quit.

ENVIRONMENT¶

PATH

Should include $TCM_HOME/bin

MANPATH

Should include $TCM_HOME/man

PRINTER

LD_LIBRARY_PATH

Should include $TCM_HOME/lib when the distribution contains shared object libraries in $TCM_HOME/lib.

FILES¶

The following relative files are relative to $TCM_HOME.

bin/terd

the entity-relationship diagram editor.

bin/psf

a program to filter PostScript output.

lib/banner.ps

PostScript banner page that can be used when the printer does not print a banner page.

lib/help/*

The help directory contains a collection of text files for the on-line help.

lib/TCM

X Resources (the same as the ones that are built-in). You can customize the fonts and colors by setting resources in your X defaults database. Each string of the form ``TCM.resource:definition'' sets a resource.

Each user of TCM can override some of the options of tcm.conf by its own configuration file, installed in $HOME/.tcmrc.
