Re: Vendors of Ada ADTs

[Jerome_V_Vollborn@cup.portal.com]

Bill Wolfe sent a note saying that I should clarify my previous posting.

EVB Software Engineering has a package of ADT's that generally follow Grady 
Booch's taxonomy.  They are a family of generic packages for stacks, lists, 
queues, ... There are versions of each ADT for managed/unmanaged, single user/
multi-user, balking/non-balking, ... Write to EVB and they will supply a 
sales brochure with all of the details.

Each of the components has three major pieces:  a design description, a test 
program, and the Ada code.  The design description and test cases will answer 
Dr. McKay's questions (what services are provided, how well are the services 
provided, and under what circumstances) without having to reference the code 
itself.

The most impressive things about the GRACE package (to me at least) are (1) 
the design documentation is complete for all of the components; (2) the 
components are consistantly well commented, documented and tested; (3) the 
code is very clean and a very good example of what Ada code should look like 
(e.g., exceptions are only used for exceptional conditions not as sneaky 
goto's as in Grady Booch's book on reusable components); and (4) Ed Berard 
envisions these components as the equivalent of SSI IC's in the hardware 
world.  Note that the GRACE components have the three elements necessary to 
be truly reusable:  a design document element, test cases, and source code.

The address for EVB is:

I don't have the name of the lady who handles the orders and shipping.  I 
have changed companies recently and her name got lost.
