I have some queries you can run against the INFORMATION_SCHEMA
Run this to get the Total MySQL Data and Index Usage By Storage Engine
SELECT IFNULL(B.engine,'Total') "Storage Engine",

CAVEAT
In each query, you will see (SELECT 3 pw)
. The pw stands for the Power Of 1024 to display the results.
(SELECT 0 pw)
will Display the Report in Bytes
(SELECT 1 pw)
will Display the Report in KiloBytes
(SELECT 2 pw)
will Display the Report in MegaBytes
(SELECT 3 pw)
will Display the Report in GigaBytes
(SELECT 4 pw)
will Display the Report in TeraBytes
(SELECT 5 pw)
will Display the Report in PetaBytes (please contact me if you run this one)
Here is a report query with a little less formatting:
SELECT IFNULL(db,'Total') "Database",
datsum / power(1024,pw) "Data Size",
ndxsum / power(1024,pw) "Index Size",
totsum / power(1024,pw) "Total"
FROM (SELECT db,SUM(dat) datsum,SUM(ndx) ndxsum,SUM(dat+ndx) totsum
FROM (SELECT table_schema db,data_length dat,index_length ndx
FROM information_schema.tables WHERE engine IS NOT NULL
AND table_schema NOT IN ('information_schema','mysql')) AA
GROUP BY db WITH ROLLUP) A,(SELECT 1 pw) B;
Give it a Try !!!
UPDATE
I just ran the first query as is on a client's DB
mysql> SELECT IFNULL(B.engine,'Total') "Storage Engine",
-> CONCAT(LPAD(REPLACE(FORMAT(B.DSize/POWER(1024,pw),3),',',''),17,' '),' ',

-> SUBSTR(' KMGTP',pw+1,1),'B') "Table Size" FROM

It works as is.

Best Answer
What you want is called either Forward engineering (create a new set of schemas + db objects based on your model) or Synchronization (apply changes in your model to an existing setup and incorporate changes from that setup into your model). The latter feature works best if you first reverse engineered an existing setup into a model and work from there. Synchronization does a 2-way merge and allows to manually exclude changes from being taken over to the other side or even change the direction for changes, if the automatic detection is not right.
