Design and integrate the database
Prototype for design details
Design and integrate the sys tems control
Nowadays, many new systems are being installed in network and
client-server environments. During design, there are elements
combined to yield an integrated user interface. Most new information
systems
must also communicate
with order existing systems called the
systems interface. Database and information files are an integral part of
information systems for business. The database for the specific system
must also be integrated with information database of other systems
already
in
use.
To
verify
the
correctness
of
the
proposed
design,
we
can build working prototypes of parts of the system. Finally, every
system must have sufficient controls to protect the integrity of the
database and the application program.
2.2.2.4 Systems Implementation
The
implementation phase is the fourth phase of the SDLC, during this
phase; the final system is built, tested, and installed. The objective of
this phase is not only to produce a reliable, fully functional information
system but also to ensure that
users are
all
trained and
that the
