1.7. Glossary
- business process:
-
A structured, measured set of activities designed to produce a specific output for
a particular customer or market. It implies a strong emphasis on how work is done
within an organization, in contrast to a product focus’s emphasis on what. A process
is thus a specific ordering of work activities across time and space, with a beginning
and an end, and clearly defined inputs and outputs: a structure for action. Taking
a process approach implies adopting the customer’s point of view. Processes are the
structure by which an organization does what is necessary to produce value for its
customers.
(Davenport 1993)
- caching technique:
-
Caching is a technique widely used in computing to increase performance by keeping
frequently accessed or expensive data in memory. In the context of a Web application,
caching is used to retain pages or data across HTTP requests and reuse them without
the expense of recreating them.
There are different types of caching is used in a web application, ASP.Net e.g. supports
the following:
- Output caching, which caches the dynamic response generated by a request.
- Fragment caching, which caches portions of a response generated by a request.
- Data caching, which caches data programmatically.
- channel:
-
One of many information sources of one application area.
- data integrator:
-
Organization which combigns variable data and databases of different functional units
for a specific application area.
- market analysis:
-
Documented investigation of a Market that is used to inform a firm's planning activities
particularly around decision of: inventory, purchase, work force expansion/contraction,
facility expansion, purchases of capital equipment, promotional activities, and many
other aspects of a company.
(Krees et al. 1994)
- modules:
-
Modules are those components that high level services consist of. Modules exist like
mapping, positioning, attribute search etc..
- portal:
-
A Portal is used to integrate modules of high level services and to make them accessible
to the users of a service.
- prototyping:
-
Process of quickly putting together a working model (a prototype) in order to test
various aspects of a design, illustrate ideas or features and gather early user feedback.
Prototyping is often treated as an integral part of the system design process, where
it is believed to reduce project risk and cost. Often one or more prototypes are made
in a process of iterative and incremental development where each prototype is influenced
by the performance of previous designs, in this way problems or deficiencies in design
can be corrected. When the prototype is sufficiently refined and meets the functionality,
robustness, manufacturability and other design goals, the product is ready for production.
- shadowing:
-
Observation of a user with the application in the envisaged context of use. In shadowing,
a researcher follows a user during their time with the system, observing and recording
any problems and questions the user has. The researcher never offers any information
but only answers the questions of the shadowed visitors.
- substitution services:
-
Substitution services are sources of
information the location-based service aims to replace. Examples are web sites,
field guides for flora and fauna (e.g. bird books), CD-ROMs, and paper maps. On
the one hand the LBS needs to go beyond what these can supply, on the other they
need to integrate information found in these sources to provide a new channel
for presenting them.
- value-chain:
-
Business management concept. Describes a chain of activities a product passes through.
The value-chain gives the product more added
value than the sum of added values of all activities.
