ad hoc query - ANS-A "spur-of-the-moment" question
analytical database - ANS-A database focused primarily on storing historical data and
business metrics used for tactical or strategic decision making
availability - ANS-In the context of data security, it refers to the accessibility of data
whenever required by authorized users and for authorized purposes
centralized database - ANS-A database located at a single site
cloud database - ANS-A database that is created and maintained using cloud services,
such as Microsoft Azure or Amazon AWS
data - ANS-Raw facts, or facts that have not yet been processed to reveal their meaning
to the end user
data anomaly - ANS-An abnormality of the data in which inconsistent changes have
been made to a database (For example, an employee moves, but the address changes
is not corrected in all files in the database)
data dependence - ANS-A data condition in which data representation and manipulation
are dependent on the physical data storage characteristics
data dictionary - ANS-A DBMS component that stores metadata. Contains the data
definition, as well as their characteristics and relationships
data inconsistency - ANS-A condition in which different versions of the same data yield
different results
data independence - ANS-A condition in which data access is unaffected by changes in
the physical data storage characteristics
,data integrity - ANS-In a relational database, a condition in which the data in the
database complies with all entity and referential integrity constraints
data management - ANS-A process that focuses on data collection, storage, and
retrieval.
data processing (DP) specialist - ANS-The person responsible for developing and
managing a computerized file processing system
data redundancy - ANS-Exists when the same data is stored unnecessarily at different
places
database - ANS-A shared, integrated computer structure that houses a collection of
related data including end-user data (raw facts) and metadata (data about the data)
database design - ANS-The process that yields the description of the database
structure and determines the database components. The second phase of the database
life cycle
database management system (DBMS) - ANS-The collection of programs that manages
the database structure and controls access to the data stored in the database
database system - ANS-An organization of components that defines and regulates the
collection, storage, management, and use of data in a database environment
desktop database - ANS-A single-user database that runs on a personal computer
discipline-specific database - ANS-A database that contains data focused on specific
subject areas
enterprise database - ANS-The overall company data representation, which provides
support for present and expected future needs
field - ANS-An alphabetic or numeric character or group of characters that defines a
characteristic of a person, place, or thing. (for example, a person's SSN, address,
phone number, and bank balance all constitute fields)
file - ANS-A named collection of related records
, general-purpose database - ANS-A database that contains a wide variety of data used
in multiple disciplines
hub - ANS-A warehouse of data packets housed in a central location on a local area
network. It contains multiple ports that copy the data in the data packets to make it
accessible to selected or all segments of the network
information - ANS-The result of processing raw data to reveal its meaning. It consists of
transformed data and facilitates decision making
islands of information - ANS-In the old file system environment, pools of independent,
often duplicated, and inconsistent data created and managed by different departments
knowledge - ANS-The body of information and facts about a specific subject. It implies
familiarity, awareness, and understanding of information as it applies to an environment
logical data format - ANS-The way a person views data within the context of a problem
domain
metadata - ANS-Data about data
multiuser database - ANS-A database that supports multiple concurrent users
NoSQL - ANS-A new generation of database management systems that is not based on
the traditional relational database model. It stores structured and unstructured data in
efficient ways.
online analytical processing (OLAP) - ANS-Decision support system (DSS) tools that
use multidimensional data analysis techniques. It creates an advanced data analysis
environment that supports decision making, business modeling, and operations
research
operational database - ANS-A database designed primarily to support a company's
day-to-day operations. (Also known as a transactional database, OLTP database, or
production database)
performance tuning - ANS-Activities that make a database perform more efficiently in
terms of storage and access speed
physical data format - ANS-The way a computer "sees" (stores) data
