Ada95 in business (database) software

Ada95 in business (database) software

[Mark Wallace]

Is anyone using Ada95 for database-oriented business applications?  Does
either of the principal commercial compilers (Aonix, GNAT) have a decent
(i.e., better than ODBC) interface to Oracle?  My team is evaluating
Ada95 and Eiffel for a new development effort, and we are having a hard
time identifying any sort of track record for Ada95 in this category
(business/database) of application.  All the Ada95 "buzz" seems to be
related to device drivers and embedded controller software.

We're willing to swim upstream with regard to non-mainstream languages,
because we care deeply about software quality.  However, we have neither
the expertise nor the funding to (re)create low-level code such as
database interface modules.

TIA,

Mark

Me, but not to that extend you might want to do.

Did you take a look at gnade.sf.net?

You can have a look at GNADE => http://gnade.sourceforge.net/

I don't know if anyone are using this but you kan have a look:

Mark,

You could take a look to the Ada 95 to the (Oracle Call Interface).
http://vagul.tripod.com/adaoci.html
It is also including to the GNADE.
http://gnade.sourceforge.net/

I'm intensively using it in the business application development.
I know some other russian developers using it too.
Frankly, there is no good documentation. But there is a good example showing
the main functionality,
and you can ask me directly.

A significant chunk of a secure system we developed in SPARK and Ada 95
involved SQL links to a database.  See "Correctness by Construction -
Developing a Commercial Secure System" in IEEE Software Jan/Feb 2002
pp18-25.  (Also in PDF on www.sparkada.com under publications).  ISTR we
wrote the binding ourselves but that it wasn't hard.

I am using GNADE (its ODBC binding) with GNAT. GNADE is fine [but ODBC
and its implementations is a real disaster] 

AFAIK, GNADE supports Oracle through native interface .

Oracle 7 used to have an Ada precompiler PRO*Ada. 

Now there is this SQL*Module beast. 

Looks good, but I haven't tested it yet.

I have used Oracle via ADO using GNATCOM working with huge (10s of millions
of rows) databases on call center apps very successfully. I've also created
a number of small apps using GWindows and its database components for
rapidly creating database front ends.

Last year i tried to get some information concerning
SQL*Module, but our ORACLE-Distributor here in Munich
said: "This is Army Stuff and not available for _normal_
       customers!"
I have not enough time and nerves to refuse or confirm
this above Statement - you know that ORACLE is a big
company and you will phone all the day to get a bit of
information.
In our ORACLE-Distribution i found only the Documentation
for modada ( the precompiler ), but not the executable.

I read this article (from your Web site), and, while I found it very
interesting, didn't see any mention of database or SQL.
