Add severall field from different table to post, fields per post are in same row of table

I like to add 4 or 5 extra fillout boxes to the adminpage of my post.. example: under the actual page box, i like to add the following fields: - Name - position - publications - freetext Here is the problem, i want to save this data uppon saving the post/page but it should be saved to a seperate table and in the same row. So the extra table has fields: ID Name position publications freetext I can not use the custom fields function because those are saved in a way that every field is dropped in the same table using page/post ID's ....i need to have them stored together in 1 row per post/page, This has to do with another java script on a different page that i like to use with this extra data.

Anyone can push me in the right direction? Thanks Mark
