Summary:
PSE worked with Dell to develop a bid management system for Dell's European
sales headquarters. The system is based on an n-tier architecture using Visual
Basic COM components running under Microsoft Transaction Server. The front-end
application was developed using Visual Interdev to run on Microsoft Internet
Explorer. The database was developed on Oracle 8 with extensive use of PL/SQL
stored procedures to maximise performance.
The brief
"Bid management system for Dell"
PSE were brought into this project as troubleshooters late on in the development
lifecycle. Our brief was to solve a number of bugs and performance problems in
the system prior to a fixed pilot launch date.
How we answered it
The technology for this project was decided before our involvement and was
centered on Oracle with Active Server Pages and VB components running under
Microsoft Transaction Server (MTS).
This was a difficult project due to the lack of documentation and varying
standards of coding within the part-finished solution and served as a valuable
exercise in where a project can go wrong.
Despite these problems, we worked with the Dell development team to remove the
bugs in the software and improve the performance dramatically in time for the
pilot launch date.
Considerable improvements in performace were achieved by using XML to transfer
data between the server and the client browser.
The technology we used
The following development languages and technologies were used in the
development of this solution:
