The global nature and inter-dependency
of information and resources, has lead to the necessity
in building a unified platform that would facilitate inter-operability
among heterogeneous data sources and client devices. The
aveAccess framework, apart from being an advanced Data
Integration System (DIS), facilitates heterogeneous devices
to interact with the integrated data sub-system.
The aveAccess framework forms a concrete solution encapsulating
content details, storage and retrieval of information
irrespective of location, time and resources. This framework
features an intelligent interaction mechanism between
the client devices/applications and heterogeneous resources.
Moreover, the framework, which is created as a development
platform, enable developers to customized push and pull
application without the knowledge of underlying protocols
and technologies.
The aveAccess framework makes use of a modularized, layered
structure that encapsulates the complex integration and
interfacing mechanisms. The client interface layer, which
is a powerful XML based device-mediator layer, facilitates
the interoperability of client resources with the framework.
The powerful XML based profile manager can be used to
customize user profiles and query processor provides a
common query language to interact with various resources
irrespective of their type or content. The query language
also allows for creation of views and triggers on heterogeneous
data resources as well as on user-profiles, views and
heterogeneous devices. This provides one common interface
to the users thereby allowing the user to view heterogeneous
data resources as a single entity. The data access engine,
which is a powerful XML based data integration mechanism,
integrates heterogeneous data having diversified metadata
and present it as if they are coming from a single server
resource. Data source access manager is a powerful XML
based data source-mediator mechanism that facilitates
the interoperability of server resources with the framework.
