Database Usage Scenarios

Desktop Database Scenario

The VORG System installed on the client desktop uses a database installed on the same machine. Typically this is the single user scenario, with an Access or MSDE database.

Server Database Scenario

In this scenario, the VORG System is installed on multiple client desktops, and all connect over the network to a shared database installed on one server.

Having data stored and managed in a central location offers several advantages:

1. Each object is stored in a central location where all users can work with it.

2. Separate copies of the item are not stored on each client, which eliminates problems with users having to ensure they are all working with the same information. Their system does not need to ensure that all copies of the data are updated with the current values, because there is only one copy in the central location.

3. Hardware costs can be minimized.

Because the data is not stored on each client, clients do not have to dedicate disk space to storing data. The clients also do not need the processing capacity to manage data locally, and the server does not need to dedicate processing power to displaying data.

The server can be stored in a relatively secure location and equipped with devices such as an Uninterruptible Power Supply more economically than fully protecting each client.

4. Maintenance tasks such as backing up and restoring data are simplified because they can focus on the central server.

Working Offline Scenario

This scenario is a combination of the previously presented scenarios. You already have the VORG System working with a desktop database or a server database, and you want to work offline on the same data, on a machine that does not have permanent hardware connection to the database. For example you want to work offline on your laptop at the customer's site.

The steps to achieve this with the VORG System are:

1. On the laptop machine, create a new empty database for offline use.

2. Use the Database Sync feature from the VORG System, and download the needed information from the server to your laptop. Note that for doing this, the server machine must be accessible.

3. Now you can go offline, and do your work: create new objects, modify or delete existing ones.

4. To reflect the changes you made offline to the server database, you should synchronize the server database with the laptop database, using the same Database Sync.
