Problem Domain: A leading glass processing
company based at Sydney, needed a customised improved
system, which would function as their ‘Quotation
and Invoicing System’. This system had been developed
keeping in mind to integrate this application
to a Production Planning System in the second
phase. In their previous system there were a few
shortcomings. The major shortcomings could be
divided into four categories eg.
a) Not user friendly
b) No reports available
c) Unable to add data to the masters without halting
the entire system
d) No database used.
Analysis: So after analyzing the system’s
shortcomings, we had decided to develop a new
system based upon two-tier architecture along
with the other functionalities that the client
wanted to incorporate into the system.
Benefits of Two-Tier Architecture
a) It stores the entire data in one central
location. Because data is always accessed by requesting
it from the server, everyone always knows where
to get the data they need.
b) It makes it easier for administrators
to create reports on what data is available, and
to track or monitor the use of that data.
c) It makes it easier for administrators
to save backup copies of data, and to restore
that data in case of an accident.
d) It concentrates processor-intensive tasks
on a powerful server computer, freeing up the
processors of slower client computers.
e) Increased Security for the Application
and Data
Technology: We developed the system
by using the followings
Operating System: Windows 2000/XP/98
Front - end: Delphi
Back - end: SQL Server
CASE Tool: Case Studio / Rational
