GAIN FROM FRAME
Topic: Reuse
Sean Gallagher's recent article profiles frame technology software
development as being more efficient than object-oriented programming
development, especially for code reuse. Most object-oriented software uses
inheritance for code reuse. This method leads to creation of numerous
subclasses when modifying the original codes. Frame technology is more
flexible, with reuse being set at the time of program construction.
Components are specified, such as identification and current status, when
programming and adjusted to suit the developers needs as alterations are
made to the code. One great advantage to frame technology over
object-oriented technology is that development costs and marketing times
are 84% and 70% less than the industry standards, respectively.

NEW AND IMPROVED ADA JOBS PAGE ON-LINE
Topic: Ada
The Ada Information Clearinghouse (AdaIC) has unveiled its new and
improved Ada Jobs WWW page. The page is located on the AdaIC WWW site at
<http://sw-eng.falls-church.va.us/AdaIC/jobs/index.shtml>. The new page
saves time and effort by allowing readers to post their own Ada jobs
listings, instead of first having to submit the information to the AdaIC.
By posting a listing and then clicking the "reload" button, readers can
view their messages immediately.
In addition to current Ada employment opportunities, postings can include
links to recruiters' pages, images, and articles related to the Ada job
market.
For further information, contact the AdaIC at 1-800/AdaIC-11 (232-4211).

DON'T WASTE CODE, REUSE IT
Topic: Reuse
With shrinking development cycles, increased competitive and customer
demands and skyrocketing costs, software development organizations are
striving to implement software reuse as part of their development
strategy.
The idea is simple: "recycle" the most valuable existing software components
into new strategic applications. While the importance of reuse is
straightforward, the implementation does require planning and commitment
from both management and software developers.
Reuse enables companies to grow continuously and efficiently by bringing in
new business without the expenditures and risks usually associated with
creating a product entirely from scratch.
Additionally, rapid proliferation of software makes development expertise
ever more precious. Hence, "reinventing the wheel" becomes extremely
expensive since it consumes the most experienced and valuable software
developers, barring them from creating advanced applications necessary for
business growth.
So how can companies effectively and consistently leverage their existing
software for future growth?
Development organizations must first have a clear picture of their existing
code. With many companies' software running into millions or multiple
millions of lines, this is a challenge in and of itself.
Secondly, a software component targeted for reuse does not, most likely, fit
its new usage objective. Moreover, in order to "transplant" this component
it is necessary to carve out enough of the component's
surroundings to make the transplant operational. To address this issue,
organizations must run a thorough analysis to assure completeness. Without
this, the reused software will not perform with the intended
functionality.

DACS WWW PAGE GETS NEW LOOK
Topic: Reuse
Visit the Data & Analysis Center for Software (DACS) WWW site,
<http://www.dacs>, for information on software technology. In addition
to doing some remodeling, the site has been reorganized for easier
navigation and has introduced "DACS Software Topics"--information
rich collections that focus on a variety of technology areas including
the topic of software reuse.

ENHANCED DISCOVERING ADA CD-ROM NOW AVAILABLE
Topic: Ada
The Discovering Ada (DA) CD-ROM, Version 2.0, is now available. DA is
an interactive multimedia Ada 95 tutorial produced by Intermetrics, Inc.
It is intended to help Ada 83 and non-Ada programmers familiarize
themselves with Ada 95. For DA 2.0, Intermetrics has corrected bugs
reported in Version 1.0, added a tutorial on Web Applets in Ada 95 and
syntax reference diagrams, and included the Ada 95 Rationale.
The Ada Joint Program Office (AJPO) is distributing free copies of
Version 2.0 to the Service Academies, Colleges and Universities, and Program
Managers via the Ada Information Clearinghouse (AdaIC). Interested
parties should contact the AdaIC by phone at 1-800/AdaIC-11, or via e-mail
at <adainfo@sw-eng.falls-church.va.us>.
Version 2.0 will be available commercially in December through
Intermetrics. For more information on commercial distribution, contact
Paige Conrad, Intermetrics, Inc., 617/661-1840, <pconrad@inmet.com>.

RIAT LOOKING FOR MEMBERS
Topic: Reuse
The Reuse Issues Action Team (RIAT) is an Action Oriented Group sponsored
by the SIGAda Reuse Working Group of the Association for Computing
Machinery. The RIAT supports and promotes the integration of software
reuse into the software systems engineering processes for Government and
industry. The RIAT concentrates on the mangement and business aspects of
reuse.
Membership in the RIAT is open to all persons who support the purpose of
RIAT and will actively participate. Membership is voluntary and meetings
are held monthly. Visit the RIAT web pages at
<http://columbia.ivv.nasa.gov:6600/riat/>.
