What is a Custom-Designed Database (CDD)?
A data series is a grouping of one or more items with the same clinical meaning, such as one or more items that measure weight. You can add items to a data series, and the items that you add can appear on multiple forms and study events. A data series provides you with a grouping of all study data collected for the item or items.
Note: The only place to create a data series is in a data set. the only place to create a data set is in a data mapping. To view this data in an organized way, you must map the data series to a Customer-Defined database (CDD) to view the data in an organized way.
When you create a data series, you are prompted to provide a title, RefName, and alias for the data series.
- Because RefNames must be unique throughout a study, you must create an alias if the RefName is used by a study object. Data series aliases must be unique within a data set.
- If an alias is present, it is used as the column name in the customer-defined database (CDD) or as the Clintrial item name in CIS mappings.
- If an alias is not present, the RefName is used as the column header.
