1NameName of the entity.
2SynonymsSynonyms for the entity.
3Synonym to displaySynonym to display for the entity.
4Preferred AbbreviationName that will be used for any corresponding table during forward-engineering if the Use Preferred Abbreviations option is enabled in the Engineering dialog box.
5Long NameLong name to be used in entity-name.attribute-name displays.
6FWD Engineer StrategyThis field is important when you are working with supertype and subtype entities. It defines the strategy of engineering entities to relational model tables:
7Single Table:The subtype entity metadata are included in the supertype table. There are no subtype tables.
8Table per Child:The supertype entity metadata is included in the subtype tables. There is no supertype table.
9Table for each Entity:A separate table is generated for each supertype and subtype entity.
10Based on Structured TypeIf the entity is based on a structured type, select it from the list. The entity will contain the attributes as defined in the structured type.
11Super TypeIf the entity is a subtype, select its supertype from the list. The entity inherits all attributes from the specified supertype.
12Source:Description of the source type. Examples: DDL, COBOL Copybook, IDMS Schema
13TypeClassification type, from the list defined in the General Options. Examples: Fact, Dimension, Logging, Summary, Temporary.
14ScopeFor an entity classified as Temporary, you can specify a scope, such as Session or Application.
15Allow Type SubstitutionFor a structured type with Reference disabled, or for a structured type applied to an entity, controls whether a substitutional structured type generation in the DDL is allowed.

Attribute

Lists the attributes currently defined for the entity.
The properties for each attribute include its name and data type,
and whether it is the primary unique identifier (Primary UID),
a relation unique identifier (Relation UID, comparable to foreign key),
or a required field (M, for mandatory).
To add an attribute, click the Add (+) icon; to delete an attribute,
select it and click the Remove (X) icon;
to view the properties of an attribute,
double-click in the cell to the left of the name.

Unique Identifiers

Ora_05.png
 

Lists the unique identifiers (UIDs) currently defined for the entity.
The properties for each key include its name and whether it is included in the primary unique identifier (PUID).
To make the attribute a unique identifier,
click the Add (+) icon; to make the attribute not a unique identifier,
select it and click the Remove (X) icon;
to view the properties of a unique identifier, double-click its name.

Relations

Lists any relations associated with the entity,
To view the properties of a relation, double-click its name.

Volume Properties

1Volumes:Minimum:Minimum data volume for the entity.
2Volumes: Expected:Expected or typical data volume for the entity.
3Volumes: Maximum:Maximum data volume for the entity.
4Growth Rate: Percent:Expected growth rate percentage for the entity, for each period as specified in the next field.
5Growth Rate: Year/Month/Day:The period (year, month, or day) to which the expected growth rate applies.
6Normal Form:The required normal form (database normalization) for the entity: None, First, Second, Third, or Fourth.
7Adequately Normalized?:YES indicates that the model is sufficiently normalized. NO indicates that the model is not sufficiently normalized, and that additional normalization may be required on the relational model

Engineer To
