This method of web based database integration is designed
for distributed turnkey applications using Microsoft
Access and optionally SQL Server if required. Each of
the end-users (Replica), the system administrator (Base
Replica) and the developer (Design Master) posses a
copy of the database application and are linked together
into a Replica Set. Updates to the databases in the
Replica Set are distributed in one of three scenarios.
Data changes in one Replica are synchronized with the
Hub Replica. These data changes are then
distributed throughout the members of the Replica Set
as they connect and sync with the Hub
Replica.
Design changes made in the Design Master are synchronized
with the Hub Replica. As each client
Replica is synchronized with the Hub Replica, the design
changes are distributed to all members
of the Replica Set.
Data changes in a Partial or Child Replica (Laptop)
are synchronized with their Parent Replica (Desktop).
Then the Parent Replica is synchronized with the Hub
Replica.
There are other methods of providing updates to database
information using Internet synchronization. These methods
incur additional costs and administrative manpower to
implement and manage. If you have an existing database
platform that is not MS-Access, we can still provide
the web database integration using other products. We
can provide the ability for users to add, edit, delete
and/or manipulate data using their familiar tools and
in the background, provide Internet synchronization
to keep the data up to date. Contact us for more details
on your specific hardware/software and DBMS installation.
What is Database Replication?
With Database Replication, you can create copies (replicas)
of a database, disperse those replicas
to other users, and exchange modifications to the data
and database structure among the
replicas.
Synchronizers do the work of making connections and
exchanging modifications among the members
of the replica set.
There are many different synchronization options available,
Synchronize on Demand (as needed for
Design Master), Scheduled Synchronization (for all replicas
with data changes) and Sync on Connect
(for Laptops).
There are three different synchronization methodologies,
Locally (same PC), Direct (internal
LAN) and Indirect
(Web and Laptops)
