2
Database Technologies: Databases
? Collections of data sets or records stored in a
systematic way
? Stores data generated by business apps, sensors,
operations, and transaction-processing systems (TPS)
? The data in databases are extremely volatile
? Medium and large enterprises typically have many
databases of various types
Volatile data changes frequently.
Copyright ?2018 John Wiley & Sons, Inc.
3
Database Technologies: Data Warehouses
? Integrate data from multiple databases and data silos,
and organize them for complex analysis, knowledge
discovery, and to support decision making
? May require formatting processing and/or
standardization
? Loaded at specific times making them non-volatile and
ready for analysis
Copyright ?2018 John Wiley & Sons, Inc.
4
Database Technologies: Data Marts
? Small-scale data warehouses that support a single
function or one department

16
Data Life Cycle and Data Principles (1 of 2)
? Principle of Diminishing Data Value
The value of data diminishes as they age
o Blind spots (lack of data availability) of 30 days or longer
inhibit peak performance
o Global financial services institutions rely on near-real-time
data for peak performance
o
? Principle of 90/90 Data Use
o
o
As high as 90 percent, is seldom accessed after 90 days
(except for auditing purposes)
Roughly 90 percent of data lose most of their value after 3
months

17
Data Life Cycle and Data Principles (2 of 2)
? Principle of data in context
o
o
The capability to capture, process, format, and distribute data
in near real time or faster requires a huge investment in data
architecture
The investment can be justified on the principle that data
must be integrated, processed, analyzed, and formatted in
?actionable information?

Data Analytics and Data Discovery
Defined
? Data Analytics is a technique of qualitatively or
quantitatively analyzing a data set to reveal pattersn,
trends, and associations that often relate to human
behavior and interaction, to enhance productivity and
business gain.

or complex to be analyzed using traditional data
processing techniques.

Four V?s of Data Analytics
1. Variety: The analytic environment has expanded from pulling
data from enterprise systems to include big data and
unstructured sources.
2. Volume: Large volumes of structured and unstructured data are
analyzed.
3. Velocity: Speed of access to reports that are drawn from data
defines the difference between effective and ineffective
analytics.
4. Veracity: Validating data and extracting insight that manager and
workers can trust are key factors successful analytics. Trust in
analytics. Trust analytics has grown more difficult with the
explosion of data sources.
