100 Verified Questions, Data Lineage Mastery,
and Dashboard Configuration Study Guide
(2026/2027).pdf


Topic Overview Coverage:
This set covers the Cogito Framework, including Chronicles/Clarity/Caboodle data
lineage, Radar Dashboard (IDM/IDB/IDK/IDN) build hierarchy, Reporting Workbench
(HRX/HGR/PAF) real-time reporting, and SlicerDicer (Fact/Dimension/VCG) analytical
exploration. It also addresses Security Classes, Data Governance,
and Troubleshooting common dashboard errors.




Batch 1: Data Lineage & Databases (Questions 1–35)
1. Which database is Epic’s real-time, transactional database used for daily clinical
documentation?
A) Clarity
B) Chronicles
C) Caboodle

 Chronicles is the "live" database where all Hyperspace actions occur. Clarity and
Caboodle are analytical databases [12].*
2. Data is moved from Chronicles to Clarity through a process known as:
A) Slicing
B) ETL (Extract, Transform, Load)
C) Mapping
D) Shadowing

,The ETL process typically runs nightly to move operational data into the relational Clarity
database for complex reporting [12].
3. If an analyst needs to write a report that combines Epic data with data from an
external non-Epic heart rate monitor, which database is the best choice?
A) Chronicles
B) Clarity
C) Caboodle
D) SlicerDicer
 Caboodle is designed as a data warehouse specifically to integrate Epic data with
third-party data sources [12].*
4. A manager wants to see a real-time list of patients currently in the waiting room.
Which tool should be used?
S) Reporting Workbench
B) SlicerDicer
C) Clarity Report
D) Radar Dashboard
 Reporting Workbench is the only tool that can pull real-time data directly from
Chronicles [11, 12].*
5. SlicerDicer retrieves its data from which source?
A) Chronicles
B) Clarity
C) Caboodle
D) Analysis Grid
 SlicerDicer is an analytical tool that sits on top of the Caboodle data warehouse
[12].*
6. True or False: Data in Clarity is updated instantly as soon as a doctor signs a note.
A) True
B) False
Clarity is a "relational" database updated via nightly ETL; it is always at least one day
behind [12].
7. In the Cogito data lineage, what is a "Record"?
A) A column in a table
B) A specific piece of data like a birthdate

, C) A specific entity, like a patient or a provider
D) A collection of related tables
In Epic's Chronicles, a Record represents a specific "thing" (Patient Smith), whereas
an Item (Birthdate) represents a data point [12].
8. Which reporting tool is best for "Mass Action" (e.g., sending a bulk MyChart
message to all patients on a list)?
A) Reporting Workbench
B) Radar Dashboard
C) SlicerDicer
D) Crystal Reports
 Reporting Workbench allows for "Action" buttons that can be applied to the
resulting list of records [12].*
9. What is the master file for Radar Dashboards?
A) IDB
B) IDM
C) IDN
D) IDK
The IDM master file contains the records for all dashboards [2].
10. What is the master file for Dashboard Components?
A) IDB
B) IDM
C) IDN
D) IDK
Components (individual graphs or tables on a dashboard) are stored in the IDB master file
[2].
11. Which master file is used to store "Reporting Workbench" reports?
A) IDM
B) HRX
C) IDB
D) PAF
Reports created in the Reporting Workbench are stored as HRX records.
12. In Reporting Workbench, what is the purpose of a "Template" (HGR)?
A) To store the final results of a report
B) To define the "base" of a report, including available criteria and columns
