5.1 | Tools to Convert Ingres to RDB | CUJO::MEIER | Systems Engineering Resident... | Thu Oct 08 1987 03:37 | 14 |
|
I'd like to add to the request...
I'd like information reguarding the effort/tools
to convert from INGRES to RDB...
If anyone was done convert effort in this area,
please let me know...
If you have a good idea how to do the conversion,
please send me mail.. You might get a trip to
Denver out of it....

5.2 | not likely.... but | RDGE44::ANDERSON | | Tue Sep 20 1988 13:59 | 28 |
| I'm not sure if anyone is still looking at this conference but here
goes.
It is unlikely for a company to switch from INGRES into RDB if they
have a database already developed on INGRES. It pains me to say
this but RDB is less competitive than INGRES in user interfaces
and application development tools. Rally and Teamdata does provide
some of the functionalities desired for querying or reporting with
Teamdata for end-users and Rally for Application developers. On
the other hand INGRES has ABF, RBF, QBF for end users and EQUEL,
ESQL, OSL, VIFRED, REPORT WRITER for application developers going
under a common product roof. Once they are actually on INGRES it
may be difficult to convince them to scrap the INGRES system and
convert to RDB.
As to converting the database from INGRES to RDB, I'm not aware
of any direct or indirect interface since they are competiting
products. But one possibility for a conversion of applications exist
if the client has developed their applications using EQUEL or ESQL with
a host language such as C, PASCAL, FORTRAN, COBOL or BASIC. Since
these languages are capable of embeddining RDO and EQUEL/ESQL, the
only part of the applications require conversion are query statements
and forms (and of course the database itself). There are many
similarities between the query languages so that if the person
understand both, it is not too difficult to translate them.
Hope this is of help,
Mary

5.3 | Not That Great | BROKE::BOOTH | What am I?...An Oracle? | Tue Sep 20 1988 18:02 | 27 |
| You are right and you are wrong.
Once a database decision is made, the database will stick for 3-5
years, no matter how bad that product may be. So it is unlikely
that a recent installation of any other database would convert to
Rdb.
However, the tools argument is fallacious. The Ingres tools are
loved by engineers and developers. The are notoriously inadequate
for end-users. There are Ingres sights that have abandoned the Ingres
tools in favor of SMARTSTAR. While developers represent a portion
of the market, Ingres does little to address the needs of end-users
and report-writers (generally management level employees). Rdb on
the other hand can offer a wealth of tools to all users. If the
end-users need to write reports and do financials, maybe FOCUS will
help. The development group may prefer CorVision.
Most IBM commercial accounts use 3 or more 4GLs. What story does
Ingres tell these people---"Don't worry...we have it all covered."
Hardly likely. As Digital gets more involved with the commercial
martkeplace, being able to offer such flexibility is a great plus.
The other major fact is that Ingres is a horribly inept marketing
company. Their VAX market share is now half of what it was only
3 years ago.

5.4 | 3rd party EUC tool | COOKIE::JANORDBY | | Tue Sep 20 1988 23:57 | 9 |
|
At a recent INGRES seminar, RTI announced that they are buying a
product from a Denver based company to bring an ICON/graphics based
end user tool to INGRES. I think that they must recognize a weakness
in their product line for them to buy a 3rd party's product for
end user functionality

5.6 | RDB+ vs INGRES | RDGE44::ANDERSON | | Thu Sep 22 1988 14:57 | 39 |
| RE: .3
O.K. I haven't any experience with INGRES for end-users except with
QBF and RBF (and a bit of ABF). Admitted, it may be inadequate
for some of the things end-users want. As to the decision makers
for buying a system, unfortunately end-users are not as considered
in such a decision. There are still enough managerial level users
who do not wish to 'dirty' their hand with work except for established
applications which they rely on developers for input on what to use.
I do like the range of RBD tools available for a la carte selection,
but something I have encountered in the past is that with a mixture,
not enough attention is paid to consistency and compatibility of
different products when one of the products goes into a new release.
FOCUS is a nice product but at present they only have a read interface
into RDB. In addition, more complex manipulations may be beyond the
knowledge of most end-users and tools such as TABLETALK are not
bug-free and they allow the construction of queries that are blatently
wrong.
A possibility for RDB et al is to coordinated the upgrades for
consistency and market common selection groups as a fixed menu with
a discount. This may demonstrate to some clients that RDB is not
just a database and nothing else. At present, some portion of the
market regard different DEC products are separate entities and not
as different shaped pieces that can be fitted togather for different
purposes.
I do agree with that fact the INGRES (especially U.K.) seems to
let the product sell itself rather than actively going after accounts
to their disadvantage. (although I don't know where you got the
figure that their VAX market share is half of what it was 3 years
ago). And isn't it the best way to learn about doing something by
learning from the mistakes of your competitors.

5.7 | RTI + SUN = SUN SIMPLIFY | DEBIT::DREYFUS | | Thu Sep 22 1988 17:30 | 64 |
| From .5:

>Has anyone heard any more about this ?
RTI and Sun are working on a product called SUN SIMPLIFY. I believe
it will be exclusive to Sun products for 6 months. After that, RTI can
market the product elsewhere (DECwindows, perhaps).
The product will attempt to fill perceived deficiencies in their end-user
product line.
From the Ingres User Association meeting reported on 5/23/88 (complete
minutes in outline form are elsewhere in this conference):
The product uses a bit-map interface as opposed the the character cell
stuff their products tend to use now. It is designed to support
the decision support market: it is an end user tool, not for programmers.
The three main parts of it are: The schema design tool, data browsing tool,
and query design tool.
The schema design tool follows the entity-relationship paradigm and will
allow read-write access to the design. It should be available by year end.
The data browsing tool allows users to look at tables and the relationships
between them. The relationships in the schema design are used to navigate
between tables. For example, a user could 'click' on a supplier name
to find all the parts supplied by the supplier. This part should
be available by year end.
The query design tool is a visual query writing program. Probably similar
to that which is available with the Multiplex product (Network Innovations).
Multiplex is called PClink in the Ingres product line.
The output of the query design tool is good for sending to the report writer,
spreadsheets, and graphics programs. The spreadsheet and graphics portions
are not currently available (I think the other stuff is in Beta).
This product should provide the next generation of QBF and RBF (query by forms
and report by forms). It is based upon standard window environments for
unix (VMS was uncertain 5/23/88).
The audience for the presentation was 50% workstation users. This is
considered the year of the workstation.
Restrictions:
There were no plans to support character-cell terminals with this
product.
There are no font control capabilities in the report writer (no
postscript).
There is no plan to mix character-cell and window based applications
for deployment with any Ingres development tool.
Note that Sun will be able to market this product with other database systems.
Probably this has the same 6 month restriction that RTI has in marketing
the product on other hardware platforms.

5.8 | It's Real | BROKE::BOOTH | What am I?...An Oracle? | Thu Sep 22 1988 17:41 | 6 |
| The market share numbers came from the CIC "VAX/VMS Relational Database
Market Share" surveys of '85, '86, '87', and '88. Ingres had 46%
of the market in 1985. They now have 23% of that market. I believe
that means a 50% or one-half loss of market share.

5.9 | figures please... | RDGE44::ANDERSON | | Fri Sep 23 1988 14:33 | 12 |
| I wonder if you can supply the figures from the survey? I would
be interested in seeing how RDB performed against other DBs such
as INGRES, ORACLE, etc. over time.
And can you indicated how:
1) end users
2) application developers
3) management (ie system managers)
view the different databases?

Percent of Market
Oracle 21 22 27 35
Rdb 21 28 34 28
Ingres 46 36 28 23
Most of the cpmments I have heard indicate that Ingres is the
sweetheart of the engineer/developer crowd.
End-users favor Oracle because their user tools are so good.
System managers hate both Oracle and Ingres, because they require
so much intervention.
But that's just me. System managers are rarely asked about database
issues. It's too bad, because they normally have a much more accurate
view of the product than do the developers or end-users who tend
to view the database through their friendly interfaces.

5.13 | EQUEL to Rdb SQL needed! | OFFPLS::HODGES | | Thu Aug 09 1990 18:29 | 18 |
| We have an opportunity to convert a LARGE number of INGRES sites
to Rdb as they upgrade their hardware from 780 class machines to 6000
class machines, IF we can help them understand the effort required to
go from Fortran with EQUEL to our (Rdb's) SQL.
I've talked to a few people but haven't come up with anything real
solid so far. One suggestion was to use an INGRES tool to convert from
EQUEL to INGRES version of SQL then our gateway to INGRES/SQL (ULTRIX)
and then 'hopefully' converting to RDB SQL would be
straightforward/easy, but this is a lot of steps and several unknowns.
Any body have any other ideas or any experience that would be
helpful???
Thanks in advance!

5.14 | A Suggestion | POBOX::BOOTH | MUMPS causes swelling of TP numbers | Thu Aug 09 1990 21:27 | 5 |
| Why don't you talk to SmartStar. They started with QUEL, and until very
recently, still supported it. They should have a good idea of the
effort involved moving from QUEL to SQL.

Also, if your user has developed his applications using the Ingres
Tools, it should be very easy to convert these applications to run with
Rdb. (remember that the Ingres Tools also run on Rdb)
