Cards

Term
Online analytical processing (OLAP)
Definition
manipulation of information to support decision making
Term
Online transaction processing (OLTP)
Definition
gathering and processing information and updating existing information to reflect the processed information
Term
OLTP
Definition
Supports operational processing
Sales orders, accounts receivable, etc
Supported by operational databases & DBMSs
Term
OLAP
Definition
Helps build business intelligence
Supported by data warehouses and data-mining tools
Term
database
Definition
collection of information that you organize and access according to the logical structure of the information
Term
relational database
Definition
series of logically related two-dimensional tables or files for storing information
Term
business intelligence
Definition
collective information about your customers, your competitors, your business parteners, your competitve environment, and your won internal operations-that gives you the ability to make effective, important, and often strategic business decisions
Term
data dictionary
Definition
contains the logical structure for the information in a database
Term
integrity constraints
Definition
rules that help ensure the quality of information
Term
DBMS
Definition
helps you specify the logical requirements for a database and access and use the information in a database
Term
5 important software components of DBMS
Definition
DBMS engine
Data definition subsystem
Data manipulation subsystem
Application generation subsystem
Data administration subsystem
Term
DBMS engine
Definition
accepts logical requests from other DBMS subsystems, converts them into the physical equivalents, and access the database and data dictionary on a storage device
Term
physical view
Definition
how information is physically arranged, stored, and accessed on a storage device
Term
logical view
Definition
how you need to arrange and access information to meet your needs
Term
data definition subsystem
Definition
helps you create and maintain the data dictionary and structure of the files in a database
Term
data manipulation subsystem
Definition
helps you add, change, and delete information in a database and query it to find valuable information
Term
view
Definition
allows you to see the contents of a database file, make changes, and query it to find information
Term
report generator
Definition
helps you quickly define formats of reports and what information you want to see in a report
Term
QBE (query by example)
Definition
helps you graphically design the answer to a question. (1) identify the files in which the needed info is located (2) drag any necessary fields from the indentified files to the QBE grid (3) specify selection criteria
Term
SQL (structured query language)
Definition
performs the same function as QBE, except that you perform the query by creating a statement instead of pointing, clicking, and dragging (select...from...where...)
Term
application generation subsystem
Definition
contains facilities to help you develop transaction-intensive applications
Term
data administration subsystem
Definition
helps you manage the overall database environment by providing facilities for…
Term
Create, Read, Update and Delete
Definition
CRUD
Term
security management facilites
Definition
allow you to control who has access to waht info and what type of access those people have (remember CRUD)
Term
query optimization
Definition
to minimize response times for large, complex queries
Term
reorganization
Definition
for physically rearranging the structure of the information according to how you most often access it
Term
concurrency control
Definition
what happens if two people attempt to make changes to the same record
Term
change management
Definition
how will structural changes impact the overall database...allow you to assess the impact of proposed structural changes to a database
Term
data warehouse
Definition
collection of information (from many places) that supports business analysis activities and decision making
Term
multi dimensional
support decision making, not transaction processing
only supports OLAP
Definition
data warehouses are...
Term
data-mining tools
Definition
software tools you use to query information in a data warehouse
Term
query-and-reporting tools
Definition
similar to QBE tools, SQL, and report generators
Term
multidimensional analysis (MDA) tools
Definition
slice-and-dice techniques for viewing multidimensional information
Term
data mart
Definition
subset of a data warehouse in which only a focused portion of the data warehouse information is kept
Term
digital dashboard
Definition
displays key information gathered from several sources in a format tailored to the needs and wants of an individual
Term
data administration
Definition
function that plans for, oversees the development of, and monitors the information resource
Term
database administration
Definition
function responsible for the more technical and operational aspects of managing organizational information
Term
intelligence
Definition
find or recognize a problem, need, or opportunity (diagonostic phase)
Term
design
Definition
(find fixes) consider possible ways of solving the problem
Term
choice
Definition
(pick a fix) weigh the merits of each solution
Term
implementation
Definition
(apply the fix) carry out the solution
Term
satisficing
Definition
making a choice that meets your needs and is satisfactory without necessaryily being the best possible choice available
Term
structured decision
Definition
processing a certain information in a specified way so that you will always get the right answer
Term
nonstructured decision
Definition
one for which there may be several “right” answers, without a sure way to get the right answer
Term
recurring decision
Definition
happens repeatedly
Term
nonrecurring, or ad hoc, decision
Definition
one you make infrequently
Term
decision support system (DSS)
Definition
a highly flexible and interactive system that is designed to support decision making when the problem is not structured
Term
model management, data management, user interface management
Definition
three components of DSS
Term
model management component
Definition
consists of both the DSS models and the model management system
Term
data management component
Definition
stores and maintains the information that you want your DSS to use
Term
user interface management
Definition
allows you to communicate with the DSS
Term
geographic information system (GIS)
Definition
DSS designed specifically to analyze spatial information
Term
expert (knowledge-based) system
Definition
an artificial intelligence system that applies reasoning capabilities to reach a conclusion
Term
artificial intelligence (AI)
Definition
teh science of making machines imitate human thinking and behavior
Term
neural network (artifical neural network or ANN)
Definition
an artificial intelligence system that is capable of finding and differentiating patterns
Term
domain
Definition
specific application area that an expert system is built for (accounting, medicine, ect)
Term
fuzzy logic
Definition
– a mathematical method of handling imprecise or subjective information
Used to make ambiguous information such as “short” usable in computer systems
Term
genetic algorithm
Definition
an artificial intelligence system that mimics the evolutionary, survival-of-the-fittest process to generate increasingly better solutions to a problem
Term
selection
Definition
survival of the fittest or giving preference to better outcomes
Term
crossover
Definition
combining portions of good outcomes to create even better outcomes
Term
mutation
Definition
randomly trying combinations and evaluating the success of each
Term
intelligent agent
Definition
software that assists you, or acts on your behalf, in performing repetitive computer-related tasks
Term
information agent
Definition
intelligent agents that search for information of some kind and bring it back
Term
monitorning-and-surveillance agents (preditctive agents)
Definition
intelligent agents that constantly observe and report on some entity of interest, a network, or manufacturing equipment, for example
Term
buyer agent/shopping bot

Term
data-mining agent
Definition
operates in a data warehouse discovering information
Term
user, personal agent

Term
agent based modeling
Definition
a way of simulating human organizations using multiple intelligent agents, each of which follows a set of simple rules and can adapt to changing conditions
Term
multi-agent system
Definition
groups of intelligent agents have the ability to work independently and to interact with each other
Term
swarm (collective) intelligence
Definition
the collective behavior of groups of simple agents that are capable of devising solutions to problems as they arise, eventually learning to coherent global patterns (flexibility, robustness, decentraliation, self-organiation)
