What are the standard data dimensions and data set methods?

When you create a data set, you can select standard data dimensions that enable the data set methods you need in the Data Mappings tab. Each data set method enables you to reference a particular subset of the instances of an item in a study. For example, the StudyEvent(StudyEvents) data set method returns a data set subset with data from only the specified study event. To enable the StudyEvent(StudyEvents) data set method, you select the Event standard data dimension when creating the data set.

You can use this approach if you design your data mappings before the complete specifications for your rules are known. With this approach, you can add an item to a data series without considering all of the forms and study events in which it is used. In your rule expression, you can use data set methods to select specific instances of the item.

Note: This approach is less efficient than adding an item to a data series with a data mapping type that narrows the selection of instances of the item. When possible, select for specific instances of an item when adding it to a data series.
