HSC 300 EXAM 3 QUESTIONS AND ANSWERS
Know what terms best describe bid data - Answers :a. Large volumes are voluminous,
diverse, and timely data
b. Complex data
Understand Secondary Data Sources - Answers :Data taken from a primary record and
used for a purpose different than the original use
i. Ex: Registries, indexes, traumas, cancers
Know the primary purpose of structured data entry - Answers :Structured data entry
reduces documentation variability
Know why an organization would use external secondary data - Answers
:Benchmarking, performance comparisons to other organizations
Understand strategic decisions and examples - Answers :i. Futuristic, long-term
organizational goals made by executives
Ex: for a healthcare system might include expanding the current market to a wider
geographic area. An example of strategic decision-making is marketing services to a
new demographic segment
Understand Ad hoc reports - Answers :Generated on an as-needed basis by analysts
and used one time to answer a single, specific question
Know how to define data mining - Answers :Applies artificial intelligence, machine
learning, and statistics to large data sets to discover patterns in the data
Understand data warehouses and staging data stores - Answers :Data warehouse:
Special type of database that has a single data model optimized for data analytics and
extracts and stores selected data from one or more operational databases for the
purpose of analytics decision support
b. Data in a data warehouse is historical
c. Referred as OLAP
d. Staging data store extracts and cleanses data before it is loaded in the data
warehouse
i. In designing a data warehouse, data marts, metadata repositories, and sources
systems are used
Know the purpose of data cleansing - Answers :a. The process of checking internal
consistency and duplication and identifying outliers and missing data in data sources
b. Involves correcting and enhancing the values of individual data elements and
enforcing data standards
c. Detects and removes data that are out-of-date, incorrect, incomplete, or redundant
, Understand functions of data marts - Answers :Data marts provide predetermined
analyses for use by specific business units
Know what value conflict is and an example - Answers :Value conflicts where different
data sources use different metrics as data values such as pounds versus kilograms
i. EX: data problem when integrating data from two systems that use different metrics
for measuring a patient's weight.
Know what UMLS is - Answers :a. Began in 1986 to aid health professionals and
researchers in retrieving and integrating information from a variety of sources and for
users to link disparate information systems.
b. Today, there are in excess of 100 different vocabularies and classifications complied
in the UMLS
Know how to best define data sets - Answers :a. A data set is defined as a list of
recommended data elements with uniform definitions that are relevant for a particular
use. Data sets are used to encourage uniform data collection and reporting
i. A list of recommended data elements with uniform definitions that are relevant for a
particular use
ii. Used to encourage uniform data collection and reporting
iii. Include both a description of the data elements in the data set and definitions for
those elements
Understand functional interoperability and semantic interoperability - Answers :Levels of
interoperability
i. Basic
The ability of one computer system to send and receive a message from another
computer system
Understand functional interoperability and semantic interoperability - Answers :ii.
Functional
a common message syntax between two computer systems that allow them to interpret
the message format, but not the meaning of the data being exchanged
Understand functional interoperability and semantic interoperability - Answers :Semantic
1. the data within the message can be interpreted between computer systems
Know what forward and reverse mapping is and when it would be used - Answers :a.
Forward map:
i. An older version of a code set is mapped to a newer version, for example ICD-9-CM
to ICD-10-CM
b. Reverse map:
i. Links two systems in the opposite direction, from the newer version of a code set to an
older version.
