240.0. "Does ORACLE have CASE?" by CLO::MOLLEY () Thu Nov 03 1988 17:39

    G'day,
    
    I have to make a call next week on an existing customer who decided
    to go with ORACLE over Rdb.  The main reason they cited was that
    Rdb lacked integrated CASE tools (incidentally, CASE was never
    mentioned during the evaluation period).  In any event, I'm not
    aware of a CASE capability within ORACLE.  I know they have something
    called SQL*DESIGN, but this is not really CASE.  
    
    Does ORACLE have a set of tools like VAXset that interfaces to the
    ORACLE database?
    
    Regards,
    Nik

240.1Oracle has CASE toolsNUTMEG::SILVERBERGThu Nov 03 1988 18:504
    ORACLE has released a series of CASE tools & products, most of which
    were developed in their U.K. organization.  I think their products
    are called CASE*Designer, CASE*Dictionary, and CASE*Method.
240.2What is it?BROKE::BOOTHWhat am I?...An Oracle?Fri Nov 04 1988 17:2515
    Yes, and I believe CASE*Dictionary is SQL*Design Dictionary with
    a new name. CASE*Method is simply the Oracle methodology for project
    work (radical, eh). CASE*Designer is difficult. I have seen a
    presentation and I still don't know what it is.
    
    Nonetheless, they are integrated with the Oracle database. The question
    is...what is the advantage in having this in a relational database?
    One would assume that the application development functions are
    vastly more significant than the implementation that supplies those
    functions.
    
    However, this is vivid proof that if the customer has Oracle, he
    is rather unlikely to buy VAXset.

240.3Oracle's CASE is very different from VAXset and CDDBROKE::DREYFUSMon Nov 07 1988 18:5627
Oracle's CASE tools are similar to many of the existing CASE tools
on the market - only less complete.

Basically, CASE*Dictionary is a repository for entities and attributes and
relationships between them.  This tools does not have the capability of
CDD.  CDD can be referenced in programs for data definition and then CDD
can be used to track changes and integrated different applications and
storage structures (RDB, RMS, DBMS).

CASE*Designer is an electronic drafting tool for modeling applications.  There
are much better ones on the market.  This tool is good for communicating 
design ideas pictorially if all users know how to interpret the drawings.

Other tools on the market allow you to export these drawings into documentation
systems for easy report generation.

These CASE tools will generally create the SQL data definition script so that
you can create the actual database.  They do not help you design the physical
database or tune the system.

There are similar products available for Rdb.

Digital seems to take a different approach to CASE by building tools that
automate and aid implementation.  VAXset provides code control and analysis
tools to aid in product engineering.  Oracle's tools do not aid implementation.
