SAS Clinical Data Integration
enables you to manage controlled terminology.
Controlled
terminology is a set of possible values for something.
For example, controlled terminology for the valid values of yes and
no could be expressed as (1-Yes, 2-No).
A
terminology
table is a SAS data set that contains controlled terminology
data. SAS Clinical Standards Toolkit provides CDISC terminology tables.
A
terminology
package is a group of terminology tables. The data standards
administrator creates terminology packages. The data standards administrator
manages the granularity of the terminology and the groups to which
the terminologies are available. For example, the following is the
granularity of the terminology and the group to which it is available:
-
-
the transformations that use the
controlled terminology
When a new study or
submission is created, the trial manager selects the terminology package
to use for the study or submission. This information is used by the
CDISC-SDTM compliance transformation and the SDTM to CRT-DDS transformation.
If multiple terminology
data sets are specified for a study or submission, changing the order
of the terminology data sets affects the order in which the terminology
tables are applied during a transformation. If a controlled term is
defined several times, the first value found is the value used.
