Can I store data in a 3D Matrix in Maple ?

I got this access file that I have mounted on the Microsoft SQLServer 2008 Express.
After a lot of problems (username, passwords, jarfiles, urls, jdbc drivers etc etc )
I have managed to get it to work (only blue text yippeieee) but when I run
Database:-QueryBuilder(connection) I get :

Error, (in Database:-QueryBuilder) could not get data for 'name', this option may not be supported with the current database system.

Can Maple embed ActiveX objects ?

such as discussed here www.quaccess.com/index.html

The first question: Is it possible in a procedure to combine datatypes ie

zz:=proc( X:: Matrix(datatype = [integer[2], float[8], float[8] ] ))

The second question :  If we assume that q is a floating number is convert( q, rational)  the
best way to convert a float to a integer ?

I have this Maple code that calculates the Sharpe ration= Expected return portfolio / Standard deviation return portfolio
for a pair of stocks by using permuations [ stock[i], stock[i] ]. Each stock shows up the permuation list twice first in
[ here, not here ]  and  [ not here, here ] so I just itterate over such permuation list and take a long position in the
first stock ( +1*return) and a short position in the second stock (-1*return). So I get the Sharpe ration for all
