The Entities tab enables you to configure the entities that
will be included in your model. These entities represent objects or events, which
may have properties associated with them, and these properties can be stored in your
model as well if you choose to include it. Entities are
linked to each other by relationships, which you establish on the
Relationships tab.
After you configure settings on this tab, click the Relationships tab
to continue creating your model.
- Model
- Specifies the name of the model.
- ID
- Select the ID that you want in this drop-down list to use to generate
entities for the model.
- Type in separate field
- If the entity type is in its own field, select this check box and select the
field in the Type drop-down list.
- Field Name
- This grid includes all the fields from your entity input file. Select the
fields whose data you want included in the model by clicking the
Include box for those fields.
- Select which fields you want to be indexed in your model by clicking the
Index box for those fields. Selecting which
fields to index, rather than indexing all fields in your model, results in
faster performance when writing to a model. However, if you later attempt to
query fields in your model that were not indexed, the response time will be
slower. You can query non-indexed properties using conditions, but the
performance will be slower.
- In the Index Type column, you can choose whether the data should be
indexed with or without case sensitivity. Selecting Case
Insensitivity typically results in more results from a
search. You cannot change the Index Type for an existing property unless the
entity it is associated with contains zero counts. For example, if an Entity
Person contains two properties, Name and DateOfBirth, and person contains
counts, you cannot change the Index Type for either property, even if one of
the properties contains zero counts.
