Electronic Data Processing
Transforms data into timely, accurate, and useful
information by reducing throughput, streamlining output,
and minimizing the handling of data.
Throughput: the time elapsing between data input and
information output, a measure of data processing
Streamlining: only generating output (reports) requested
by those who actually use the information

Bit: smallest unit of electronic data (either 0 or 1)
Byte: sequence of bits representing a single character
and a measurement of memory
1,024 bytes

Multidimensional Databases
Data warehouse: supports organization-wide decision
making enabling elaborate queries on large amounts of
data requiring extensive searching
Data mart: a multidimensional database organized for
one department or function
Data mining: exploring a database to uncover patterns
and relationships
Online analytical processing (OLAP): decision support
software enabling a user to quickly analyze information
summarized into multidimensional views and hierarchies
