Modeler:12/OtftEditor

Object Type / Fact Type Editor

The dialog allows editing various default properties of Object/Fact Types.

• Name (Object/Fact/Label Type name)
• Schema (Names must be unique in combination with this Schema Name)
• Plural (Plural Name)
• Abbreviation (Abbreviated Name)
• Concept (Concept Type can be anything. Default provided are: Person, Location, Event, Thing)
• Aliases (Comma seperated list of Aliases for this OTFT)
• Comments and other annotations (Comments, and annotations as declared in Custom Attribute Definitions)
• Supertype, Abstract, Subtype (Specify if the Object Type a Supertype, Subtype or even Abstract.)
• Derivable (Mark this Object/Fact Type to be derivable.)
• Transitional (The population may be gathered from various sources, potentially conflicting. The artifacts will add a source_id column to the primary key.)
• Color and Background (Visual colors for personal use.)
• Task (The lifecycle specifier for this OTFT: Conceive, Plan, Develop, Qualify, Launch, Deliver, Retire)
• Temporal (Specify which temporal aspects are relevant: Valid Time, Transaction Time or Both.)
• Reducable (Modeler option to specify if this OTFT could, should, must be reduced during model transformation.)
• Generate Artificial Key (In the artifact this Type is required to be identifier using an artificial key. The natural key will become an alternate key.)
• Static Population (The population is considered to be static, as in a reference table.)
• Estimated Tuples (Estimated amount of tuples in the final artifact.)

Label Type Editor

Label Types contain different settings and this same dialog is presented differently for them:

The dialog for Label Types is slightly different, it lacks a few from the Object/Fact Type mode, and adds the following:

• Datatype Name (The datatype name can be specified using the ellipses button. This enables supporting datatypes from different artifacts.)
• Length
• Precision
• Localize (If set, the artifact will provide an additional database table to allow production data to be translated using a locale identifier. This is typically used for multi-lingual websites where product_name might need to be notated in various languages.)

Additionally Label Types may contain Value Constraints which limit the valid population.
