Dean, depending on what tool you are using on the front-end the bulk load feature of pl/sql might be an option. Basically you have to load the data into a pl/sql table (array) and then Oracle uses array inserts to load the data into the table. See the PL/SQL manual.

The insert/select statement might be an option depending on where your data source is.

More detail of where the data comes from and where it has to go would probably allow someone to suggest viable approaches to the problem.
