Multiple tables feeding one table

Question

Hi All,
What is the best method to feed data one central table with data from multiple other tables?
Here is the scenerio/requirement:
>BI Query 1 --> VC Table 1 --|
>.........................................|
>BI Query 2 --> VC Table 2 --|
>.........................................>----> Master Table to display on VC dashboard
>BI Query 3 --> VC Table 3 --|
>.........................................|
>BI Query 4 --> VC Table 4 --|
Viewing data in the individual tables is straight forward enough, but what are the recommended methods of showing data from Tables 1, 2, 3 and 4 (which contain the same fields/structure) in a final 'master' table?
Possible approaches:
1] Referencing cells in Tables1-4 from within the master table;
2] Feeding/sending values to the master table from Tables1-4;
The reason for not simply grouping 4 initial tables together (i.e. one below another) in the first place is due to each table displaying column headers, which not only takes up unnecessary space, but also surplus to requirements, considering the structure of Tables1-4 are the same (e.g. Table 1 = sales figures for company ABC, Table 2 = sales figs for Company XYZ).
Alternative suggestions are welcomed, as are methods on achieving the two possible approaches above.
Many Thanks,
Chet.

Hi Mustafa, Basheer,
Thanks for replies, very helpful indeed - I'll give it a go...         (EDIT: just tried, so far , so good)
In the meantime...the reason I mentioned the potential option of "Referencing cells in Tables1-4 from within the master table;" is because I will also need to perform calculations based on the values found in Tables1-4. For a simple example, take a value from a specific cell in Table 2 (say, Cell1), multiply/subtract/divide by a value in a specific cell in Table 3 (say, Cell2), and display it in the 'master' display table.
My intial thoughts suggest creating a new field in the 'master' display table (of type expression box) and creating a formula, which references the two cells (Cell1 and Cell2, both of which will have to appear hidden) to perform the calculation. (I am assuming I can use the General>Data Source Field>Field Name to action this).
If you can kindly confirm this is the best approach (keeping in mind that many cells displayed in the 'master' table will calculated based on Tables1-4 - any performance issues??) , that would be greatly appreciated.
Thanks,
Chet.
