Imported Tables | Linked Tables |
---|---|
Data is local — the entire contents of an imported table are read into a copy on local storage. | Data is remote — only rows requested from the linked table are read into local storage.
Note: You can link to a local table, rather than creating a second copy by importing it.
|
Importing can take several seconds, or even minutes, depending on the size of the database. | Creating a link is almost instantaneous, depending on the network connection. |
Space is required for local copies of imported tables. | The link requires very little local storage. |
Data is static — if there are changes to the database, they are not reflected in local data. If the database is subject to frequent changes, linking can be preferable. | Data is dynamic — you have access to any changes. |
If the network connection is broken, users still have access to data. | If the network connection is broken, users have no access to data until connection is restored. |
Users cannot write to the indexed file source. | Users can write to the indexed file source if the data source name (DSN) is read/write and the user has INSERT and/or UPDATE permissions on the object |
As a guideline, re-linking or re-importing is required when the table structure — such as the number of columns, or their names, sizes, and types — changes.
The Micro Focus XDBC Login dialog box appears if you or an administrator established database security methods during Micro Focus XDBC setup. If no security methods were established, a User ID and Password are not required, and the Login dialog box will not appear.
