da Li šič IS is undergo-
ing a retooling
process in which it is embracing more
powerful technologies, including new ar-
chitectures—among them, IBM's Systems
Application Architecture (SAA) and
Digital Eguipment Corp.s Network Ap-
— plication Support (NAS)—and new
types of development tools, such as inte-
grated computer-aided software engi-
neering (I-CASE) programs.

CASE tools will play a significant role
in the metamorphosis of IS because of sev-
eral advantages. These tools support all
phases of development; and can generate
source code for an entire application from
a single repository of design specifications.

The components of I-CASE tools are
illustrated in the figure. Front-end de-
sign facilities typically include planning,
analysis and design workbenches. The
planning workbench handles strategic
planning, enterprise modeling and high-
level data modeling; the analysis work-

Specifications generated on the desktop with an CASE tool can be
consolidated on the LAN, then further consolidated on the corporate
mainframe; each level uses a common data model.

desktop [CASE tools that support the en-
tire life-cycle process and generate CO-
BOL or C source code for applications in

PC prod- : both IBM and Unix environments. These

tools will support rapid prototyping on
the desktop and will deliver database ac-
cess via the industry-standard Structured
Guery Language (SAL). a
It is important to look for ICASE
tools that are capable of generating
SAA applications that use a common
user, programming and communication
interface, and are compliant with IBM s
AD/Cycle repository CASE standard.
I-CASE products will rapidly evolve
into "industrial-strength" CASE facilities
that can be harnessed to create applica-
tions of varying complexity. Their ability
to produce complete application code on
the desktop in close concert with end us-
ers—coupled with new methodologies
such as rapid applications development —
will add to this growing phenomenon.
Another major change on the horizon is
the consolidation of design specifications
on a LAN. Until recently, a mainframe
was reguired to consolidate specifications

major ECASE vendors will support this
function on a LAN using a file server, IVEI, AS

Texas Instruments will introduce an.
OS/2 version of IEF that can be used to
generate entire applications on the desk-
top in either COBOL or C.

The offerings of these firms demon-
strate where the I-CASE tool market, is
headed. Managers should expect to see

still reguired back-end code-, database-
and documentation-generation maln-
frame components. The mainframe
code- and database-generation portions
typically cost $200,000 to $300,000, se-
verely limiting their applicability.
Within the past year, however, I-
CASE tools have rapidly matured, par-
ticularly in the area of desktop code
