Glossary	Definition
Audit Log	System feature that maintains a historical record of key actions related to a Study Subject that have run on the CheckPad database (this is part of 21 CFR Part 11 compliance).
CRF (Case Report Form)	A form that collects and contains Visit information for a Study Subject. CRFs are defined using CRF Builder
Dataset Definition	Criteria (metadata) specified to create a dataset.
Dataset	A collection of data and metadata from records such as CRFs, Visits, etc. that matches a dataset definition and is exported to a file whose format can be selected, for use in other applications.
Delete	A delete action completely removes the information from the CheckPad system. Deleted information cannot be restored, although the audit log tracks the deletion action. Nearly all information in CheckPad is removed rather than deleted because removed information can be restored.

Enrollment	Adding a Subject to a Study. The CheckPad Enrollment Date is when the Subject is added to an CheckPad Study.

Roles	Categories for users in CheckPad that determine the tasks available to them in the system.
Rules	Customized methods used to trigger actions on records such as the automatic generation of a Discrepancy Note, email, etc. Rules are stored in XML files. They can be built directly in an XML file and uploaded to CheckPad, or built in CheckPad using the Rule Designer feature.
Secondary ID	An optional identifier given to a Subject. It is often a legacy identifier like a patient record number that is used to link the Subject to another system or workflow, for example.
