USING ER/STUDIO > DEVELOPING THE LOGICAL MODEL
Dimensional tab
DDL tab
This tab is available for Dimensional Models only. Lets you set the dimensional type of the table and the data
type.
• Override Automatic Designation—If selected, the table’s type will not be changed when the Automatic Table
Type Identification process is run on a related table.
• Run Automatic Table Type Identification—If selected, when you change the Dimensional Model Table Type
and then click OK to close the Table Editor, ER/Studio automatically changes the type of other tables to reflect
the change, using the same logic as it does when creating a new dimensional model from a logical model. For
example, if you change a table’s type from Dimension to Fact, its parent’s type can change from Snowflake to
Dimension.
Displays the DDL to create the table. The DDL shown here includes code to reproduce the table including all its
properties, as defined on the tabs of the Table Editor. You can edit the code if you like. You can customize the
DDL that appears to include only include the options you want. For more information, see Customizing Table
DDL.
Indexes tab
Add, edit, or delete indexes. Provides access to the Index Editor. For more information, see Creating and Editing
Indexes.
Foreign Keys tab
View any relationships that exist between the selected table and other tables in the model. Information included
about the relationships include the relationship type and the Foreign Keys. For more information, see Creating
and Editing Keys.
Definition tab
Note tab
Enter or edit a definition for the table. If the target database supports it, ER/Studio adds this definition as a table
comment when generating SQL code.
The notes added here are included as part of the HTML report when you generate a report for the model. You
can format the notes using standard HTML tags.
Where Used tab
Shows which logical and physical models and submodels implement the table.
User-Defined Mappings tab
Shows any user-defined mappings (UDM) for this table. UDMs tie data together that can be conceptually related
but not necessarily with concrete transactional relationships. UDMs are not used when comparing data models
or when generating SQL. Use the Note tab to describe the relationship between entities that is created using
user-defined mappings. For more information, see Associate Similar Objects Using User-Defined Mappings.
Storage tab
Lets you select various storage options depending upon the selected database platform. For more information,
see Defining Table Storage.
