wwHww : An Application Framework of Distributed System for Enduser-Initiative Development
ABSTRACT of the paper : APSEC'98, IEEE Computer Society, pp.102-109 (Dec. 1998).
The number of endusers using the Internet
increases on the inside and outside of offices.
Enduser-initiative development of applications has become important
for automation of their own tasks.
As the solution by software reuse technology,
this paper describes an Java-base application framework of
the distributed systems such as the MOON
(multi-organizational office network) systems for window work in
banks, city offices, mail-order companies, etc. based
on the philosophy :
``All routine work both at office and at home
should be carried out by computers.''
The application framework includes a common protocol for application forms
and is composed of
subframeworks corresponding to the three kinds of parts of client
terminals, server-at-windows and the MOON servers.
With respect to the problem of how to customize the application framework
in the way of enduser-initiative development,
two types of customization are given,
namely, plug-in components and property definitions.
Then domain experts can computerize their routine work by themselves.
Our feasibility study confirms that
the frozen spots and the hot spots in the framework
account for 90 % and 10 % of the total Java source programs respectively.
Furthermore, use of the application framework
including a common communication protocol between clients and servers,
brings high interoperability among distributed application systems.
Key words :
distributed system, Internet and intranets,
application framework, object-oriented technology, enduser computing
