How does
our Applications work?
Solutions for Remote Data
Access.
We use
ADO! ADO enables your application to directly gain
access to and modify data sources (sometimes called a
two-tier system). For example, if your connection is to
the data source that contains your data, then that is a
direct connection in a two-tier system.
However,
we have accessed data sources indirectly through an
intermediary such as Microsoft Internet Information
Server (IIS). This arrangement is sometimes called a
three-tier system. IIS is a client/server system that
provides an efficient way for a local, or client,
application to invoke a remote, or server, program
across the Internet or an intranet. The server program
gains access to the data source and optionally processes
the acquired data.
Our application's Web pages are written in ASP and HTML, which connects to IIS.
Further,
we have added a Simple ActiveX Form for demonstration
purposes only. IIS in turn connects to the actual
data source, retrieves the data, processes it then
returns the processed information to our application.
We
developed a simple, efficient application programming
interface that supports three-tier systems, and returns
information as easily as if it had been retrieved on a
two-tier system. Remote Data Service (RDS) is this
interface.
