Multidimensional Model in Data Modeler

Question

Hello
I have two questions about multidimensional models:
Firstly:
I know tutorial about this topic (Data Modeler Web), but it is not about creating model.
I have very simply example:
1.Logical model with one fact entity and three dimension entity (fact, dim1, dim2,dim3). Entities have atrybut Type: fact and dimension. Dim1, dim2 and dim3 has id_dim1... they are FK with fact.
2.I generate relational model - is OK.
3.Now I would like create multidimensional model with one cube. It should have three dimensions with id_dim1, id_dim2 and id_dim3 and measures as sum(account), where account is a part of entity fact (number).
I would like to now what should I do step by step. Please.....
Secondly:
If I create this multidimensional model I would like generate script *.sql to create physical database objects . Is it possible?
Thank You

Hi,
you can try this tutorial http://www.oracle.com/technology/obe/datamodeler/datamodel3genmulti/datamodel3genmulti.htm
It shows how to create dimensional model from reverse engineering of SQL dimensions like this one:
CREATE DIMENSION customers_dim
     LEVEL customer     IS (customers.cust_id)
     LEVEL city      IS (customers.cust_city)
     LEVEL state      IS (customers.cust_state_province)
     LEVEL country      IS (countries.country_id)
     LEVEL subregion IS (countries.country_subregion)
     LEVEL region IS (countries.country_region)
     HIERARCHY geog_rollup (
          customer     CHILD OF
          city           CHILD OF
          state           CHILD OF
          country      CHILD OF
          subregion      CHILD OF           
          region
     JOIN KEY (customers.country_id) REFERENCES country
     ATTRIBUTE customer DETERMINES
     (cust_first_name, cust_last_name, cust_gender,
     cust_marital_status, cust_year_of_birth,
     cust_income_level, cust_credit_limit,
cust_street_address, cust_postal_code,
cust_main_phone_number, cust_email)
ATTRIBUTE city DETERMINES (cust_city)
ATTRIBUTE state DETERMINES (cust_state_province)
     ATTRIBUTE country DETERMINES (countries.country_name)
ATTRIBUTE subregion DETERMINES (countries.country_subregion)
ATTRIBUTE region DETERMINES (countries.country_region)
