Management Information
System—Purpose
 Monitor progress toward goals.
 Measure performance.

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
efficiency
Streamlining: only generating output (reports) requested
by those who actually use the information

Bits and Bytes
Bit: smallest unit of electronic data (either 0 or 1)
Byte: sequence of bits representing a single character
and a measurement of memory
Kilobyte
1,024 bytes
Megabyte
1,048,576 bytes
Gigabyte
1,073,741,834 bytes
Terabyte
approximately 1 trillion bytes

Hierarchical Database Structures
 Files, records, fields arranged like roots of a tree
 Precise data searches
 Comprehensive statistical analyses
 Rigid perameters
 Time-consuming to incorporate new data definitions

Relational Database Structures
 Files, records, fields formatted as rectangular tables of
rows/columns
 Popular due to simplicity of data arrangement
 Ease of data manipulation
 Flexibility of data handling

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
