Gr 12 4.3 – DATA COLLECTION, WAREHOUSING, MINING Flashcards
Invisible data capture
A type of data capture that usually happens when
you allow data to be captured for a specific purpose,
and other data not strictly required for this purpose
is also captured, often without your awareness.
Data collection
Any method of obtaining data to be processed.
(Distinguish carefully from the process of ‘collecting
data’ for academic/research purposes.)
Data mining
The use of complex algorithms to group and arrange
‘big data’ so that interesting and previously unknown
patterns emerge – and new information is
discovered.
Data warehouse
A huge collection of data, often accumulated from a
range of sources such as separate databases within a
company.
Location based data
Data that is linked to a specific location – usually using co-ordinates captured by a GPS device.
RFID
Radio Frequency Identification – a data capture
technology designed to store more data and work
more interactively than conventional barcode
systems.
RFID reader
The component of the RFID System designed to read
information in RFID tags when ‘swiped’ past it or brought
within suitable reading distance, and then to initiate
processing of the data received.
RFID Tag
The component of the RFID system designed to be ‘read’
and therefore placed on items that need to be tracked or
interacted with.
SQL
Structured Query Language – a standard language used for
querying and manipulating data in a database.
