  1. Newbie disturbed about lack of CASE tools for PostgreSQL

    Scott Alexander <scott.alexander@mindspring.com> — 1999-06-12T05:22:36Z

    Hello again -
    
    I recently asked people what their favorite CASE tool was for defining
    PostgreSQL databases and have gotten almost no answers - except one
    person who said they don't *use* PostgreSQL for databases over 60 tables
    precisely because of the lack of such support.
    
    I'm new to the Linux world and I'm unsure what kinds of stuff people are
    doing in it. 
    
    One the one hand it sounds like Linux users are highly capable because
    they seem to be more aware of the "inner workings" of their computers
    and code. One the other hand, I sometimes worry that Linux users might
    be less productive than people in other OSes because you might more
    willing to put up with a lack of support tools, maybe as part of some
    kind of do-it-yourself or roll-your-own or command-line-mode ethic.
    
    CASE tools are not a luxury for database design - just because they're
    usually visual and work at a "higher level" (linguistically) than
    implementation-level database design tools (an example of a lower,
    "implementation-level" tool would be what I dread you're all defining
    your databases in - a raw text editor where you key in your SQL DDL
    statements) - just because high-level design tools are often easier and
    more visual to use doesn't mean they're somehow "bad" - it just means
    they're part of a great tradition in mathematics and computer science -
    the development of ever higher-level (ie more compact and expressive)
    languages and the corresponding compilers that translate them down to
    the lower-level (lengthy, repetitive, error-prone, machine-writable)
    languages... like SQL.
    
    I'm not trying to flame here, but I *am* trying to light a fire under
    people... Does the word "data dictionary" mean anything to PostgreSQL
    users? Does this thing exist in some other form than what I'm used to?
    Can anybody out there please tell me their convenient real-world
    methodology for creating PostgreSQL databases? (Everyone who's just
    raw-coding SQL in a text-editor please raise your hands.) 
    
    Everything about Linux and PostgreSQL is so open I'd be very surprised
    if there weren't some kind of simple (ie, visual) tool for defining
    tables, columns and relationships on a Linux machine and then pushing a
    button and having the tool spit out a complete SQL script in the pgsql
    version of your choice defining the database you just "drew". 
    
    I mean, such a data-modeling tool could be written quite quickly in tcl
    it seems like, and distributed as open-source. And since I'm a
    Linux/PostgreSQL/tcl newbie, I'm hoping someone's written something that
    already so I can roll up my sleeves and start defining syntactically
    correct PostgreSQL databases right off the bat. Or is defining a
    Linux-based visual data-modeling and
    SQL-generating(-and-reverse-engineering) tool going to have to be my
    first task as a Linux database programmer? At the very least, is there a
    data-modeling tool that runs under Unix(/Linux?) that permits some
    degree of end-user parameterization over target SQL dialects, so that we
    could just define PostgreSQL as a target dialect for it?

    Well, recently i've found "Toolkit for Conceptual Modeling (TCM)", but
    i guess it's tool for design only (erd) and doesn't support
    sql-generation
