25
PC virtualization
a personal computer hosts several different operating systems
26
columns are also called | rows are also called
fields | records
27
Key (aka primary key)
a column or group of columns that identifies a unique row in a table
28
foreign keys
values of the foreign key match values of the primary key in a different table
29
relational databases
they are databases that carry data in the form of tables and that represent relationships using foreign keys.
30
metadata
this data describing data
31
DBMS
database management system they create, process and administer a database ex. Access,SQL,mySQL
32
SQL
Structured Query Language | it is an international standard language for processing a database.
33
database application
it is a collection of reports, queries,and application programs that serves as intermediary between users and database data.
34
data model
before building a database developers construct a logical representation of database data
35
E R data models
tools for constructing data models (entity-relationship data models)
36
Entity
they are what you want to track | ex. order, customer salesperson, an item
37
identifier
it is an attribute (or group of attributes) whose value is associated with only one entity instance ex. order number, customer number
38
crow's feet
shorthand for multiple lines between "departments" and "advisers" (one-to many relationship 1:N)
39
Normalization
it is the process of converting a poorly structured table into two or more well structured tables
40
lost update problem
(database application problem)two users update the same data item but only one of those changes is recorded in the data.
41
maximum cardinality
the maximum number of involved entities that can be involved in a relationship ex. 1:N N:M 1:1
42
define the cloud
it is the elastic leasing pooled computer resources over the internet.
43
what does elastic mean
that the computing resources leased can be increased or decreased dynamically, programmatically, in a short span of time and that organizations pay for just the resources that they use.
44
how does the cloud pool resources?
different organizations use the same physical hardware; they share the same hardware through virtualization
45
three types of networks
LAN WAN (computers connected between two or more separated sites) internet and internets
46
Intranet
private internet that is used exclusively within an organization
47
protocol
a set of rules and data structures for organizing communication
48
SOHO
small office or Home Office
49
IEEE 802.3 protocol
used for wired LAN connections (using ethernet)
50
IEEE 802.11 protocol
Wireless LAN connection
51
DSL
Digital Subscriber Line
52
carriers are
large telecommunication providers | ex Sprint AT&T Verizon
53
difference between Public and Private IP adresses
public identify a particular device on the public internet | Private identify a particular device on a private network
54
Tree tier architecture includes
1. the user Tier 2. The server tier 3. the database tier
55
user tier
consists of computers, phones and other mobile devices that have browsers that request and process web pages
56
database tier
consists of computers that run a DBMS that processes requests to retrieve and store data
57
server tier
consists of computers that run web servers and process application programs
58
SOA
Service-Oriented Architecture it is a design philosophy that dictates that all interactions among computing devices are defined as services in a formal, standardized way.
59
TCP/IP protocol architecture
has five layers | one or more protocols are defined for each layer
60
smtp
Simple Mail Transfer Protocol
61
ftp
File Transfer Protocol | ex Microsoft Onedrive
62
SaaS
Software as a service provide infrastructure, operating system and application programs ex. iCloud, Office 365
63
PaaS
Platform as a Service vendors provide hosted computers, an operating system, and possibly a DBMS ex. Microsoft Azure
64
IaaS
Infrastructure as a Service the cloud hosting bare server computer of data storage ex. Amazon S3 (simple storage service)
65

is a system of hardware and software that stores user data in many different geographical locations and makes data available on demand
66

68
differences between structured processes and dynamic processes
structured processes support operational and managerial processes but dynamic support strategic Ex. Structured: Customer Returns Dynamic: collaboration
69

72
workgroup IS are also called
functional information systems
73
Enterprise processes are
span an organization and support activities in multiple departments
74
characteristics of Enterprise IS
100-1000+ users eliminates workgroup data duplication difficult to change
75
Inter-enterprise
they span two or more independent organizations.
76
characteristics Inter-enterprise IS
supports one or more inter-enterprise processes 1000+ users can resolve problems of duplicated enterprise data very difficult to change
77
Process efficiency
a measure of the ratio of process outputs to inputs
78
process effectiveness
is a measure of how well a process achieves organizational strategy
79
How can a process be improved?
change the process structure change the process resources change both process structure and resources
80
How can IS improve process quality?
performing an activity Augmenting a human who is performing an activity controlling data quality and process flow
81
Information silo
it is a condition when data are isolated in separated information systems
82
What is the problem of Information Silos?
when an org. has inconsistent duplicated data then your problem is data integrity.
83

Enterprise Resource Planning a suite of applications called modules, a database and a set of inherent processes for consolidating business operations into one platform.
87
EAI
Enterprise Application Integration | software that integrates existing systems by providing layers of software to connect the applications together
88
EAI does the following
1. connects system's "Islands" via a new layer of software/system 2. allows existing applications to communicate and share data 3. leverages existing systems 4. allows for a gradual move to ERP
89
elements of an ERP system
``` hardware ERP application Programs ERP databases Business Process Procedures Training and consulting ```
90
types of program code for database
