- We are starting a project in which we must make a set of databases
- available to users over a wide area network...
- We are looking for help/advice in designs/implementations of
- similar database systems...We are especially interested in case studies.
-
- We are curious about designs/implementations of different architectures
- such as:
- 1. Centralized database servers that users log into to run their
- applications...
- 2. Truly distributed databases...i.e. data distributed amoung several
- database severs with no redundant data....has the appearance of
- a single database....
- 3. Distributed databases with redundant data stored at some sites...
- ...strategies for keeping databases consistent and strategies
- for updating each db...
- 4. Other????
-
- To give a few more specific characteristics of the system we are
- working with:
-
- * We will be using a third party RDBMS such as Ingres or Oracle
- * A wide area network is already installed
- * All machines over the network "talk" TCP/IP
- * There is a near real-time data collection/distribution component
- (i.e. data collected about once an hour needs to be made
- available to users over the network)
- * Most of the data queries need to be through interactive
- data communications...i.e. not batch transfer of files or
- media transfer...
-
- Responses sent directly to me would be greatly appreciated...
- (unless you feel this would be of interest to other readers in
- this news group)
