| Well roughly speeking you would have to add almost every extras to
Ingress to match Rdb.
Rdb Comes with
All precompilers
SQLMOD
SQL Dynamic
Pc Acces
Tuning tools
Administration tools
Networks access
Referential integrity
Ingres would have to match this
casing the price to be MUCH MUCH higher than Rdb.
Also note that While Rdb adds on to the base-engine ie new versions
provide the new features, Ingres has started of the same line as
Oracle, ie unbundle new features in new packages causing a price AND
maintenance-price jump for new versions if the features are wanted by
the customer.
of another tangent is the fact than Rdb will outperform and outfeature
Ingres in close to every detail you might think of.
Rdb V4.0 outperformas Ingres in almost any occation but lack features
especially around date-time.
Rdb V4.1 will blow Ingres to pieces regarding performance (unless they
get a row-locking feature and a MUCH MUCH improoved UNDO REDO loggin
implemented) ad will provide date-time support and in ANSI/ISO
compatible syntax (which Ingres is not).
Hope this helps
Lars
Ps. Should you need to know anything special about Ingres always try
the Ultrix/SQL notes conference as this is essentially Ingres-Db

| Re: .1 Thanks, that information is usefull but I am still looking for
the actual INGRES product names needed to equal as close as possible
the capabilities of Rdb Run-Time and Rdb Development in a 4GL
environment.

| Paul,
I'm by no means an Ingres expert but here goes...
The Database components that Ingres has unbundled from their Base
engine are Knowledge and Object Manager as you stated.
Knowledge Manager allows you to add rules to the database. Sim=ilar
in function to Constraints and Triggres inside of Rdb. If
constraints and triggers are required then you will have to add
Ingres Knowledge Manager to get similar funxtionality. Knowledge
manager also has a resource limiter.
Object Manager allows you to define an object with user define
datatypes an functions to be performed on that datatype. For example
Object management could be used to store Images or other
non-traditional data types in their database. I believe that you
need Knowledge manager to use Object Manager, but I'm not 100% sure.
Rdb has segmented strings, but nothing announced which competes
directly with Object Manager.
I have heard that Ingres is using the technique you described when
selling to an ULTRIX customer. They are trying to give the impression
that ULTRIX/SQL is not as good as the Ingres database and that if you
want all the features of their database you need to buy it from Ingres.
I have not heard them using this strategy on VMS where it only
accentuates the proce difference.
If this does not help, I second .1 suggestion to post it in the
ULTRIX/SQL notes file where someone will be more KNOWLEDGEable
about Ingres's KNOWLEDGE and OBKECT managers.
