Hi Prasad,
Is the data independent on every table or does it have some sort of correlation?
Say, sales and proposal would have keys that are related, so you could have them linked by a common key (let's say [Node Name] and [Date]) and make all the associations follow the same rule.
Or they could be excludent, say HR info and Sales Orders, and for that case you could create a linktable with the concatenated fields from each table do denote each information individually.
Additionally, since you have them linked by the key, you would be able to take those fields of the individual tables, so that only a central table contains all the possible variations.
