Transformation Class/Entity to DDL

[cg.schaefer]

We used EA 7.1 Example Model.
There is a nice Domain Model (order, account..)

i tried to transform the order to DDL with project -> transform
the string is transformed correctly, the date is not.
for example the date is transformed to date also for sql server, but the sql server does not support date.

where is a list of available datatypes which are recognised in the DDL.
why is there no mapping dialog from custom language to DDL language ?
