MIS Exam 1
CHAPTER ONE
in-class assignment and homework one — access
views, datasheet view, design view, and SQL view
for the slides (1-31)
slide 3 and 4
the laws —
bells law - highly successful business could be bankrupt quickly because technology changed, and it didnt.
moores law - the number of transistors per square inch on an integrated chip, 2x(18 month)
metcalfes law- value of a network = # of users connected
nielsens law- network connects speeds for high end users increases 50% per year
Kryders Law- storage density on magnetic disk increases exponentially
slide 9, 10, 11, 12, and 13
summary of the skills
abstract reasoning - construct a model or representation
systems thinking- model system components and show how components inputs and outputs relate to one another
collaboration- develop and planning with others, provide and receive critical feedback
ability to experiment- Create and test promising new alternatives
then a deeper dive into the skills
slide 15
definition of MIS and IS
MIS- management and use of information systems that help organizations achieve their strategies
IS- hardware, software, data, procedures, and people together to produce information
slide 17 and 18
five components of information systems
hardware, software, data, procedures, and people
IT and how its related to IS (IT, plus procedures and people, is IS)
IT drives development of IS
IT is hardware, software, data
slide 21 and 22
the five components and their relationship to eachother
hardware and people are actors
softwares and procedures are the instructions
data is the bridger between computer side and human side
we cannot buy information systems, but we can buy IT. Procedures are specific to companies and firms
slide 24
information data
information is knowledge derived from data
data is recorded facts or figures
slide 26
a graph is not information, its how you present the data
the interpretation of the graph is information perceived by people
slide 27
characteristics of data
accurate
timely
relevant
just sufficient
and worth it’s cost
CHAPTER TWO
for the slides (1-23)
slide 3
covers five-force model, the graph
industry structure (rivalry, threat of substitutes, bargaining customers) →
competitive strategy →
value chains →
business processes →
information systems (is)
slide 5, 6, 7 and 8
summary of the five forces
bargaining power of customers- strong force is a big company purchasing a lot from you, weak force is your ability to change rules and procedures at university.
threat of substitutions- weak force is when your product is completely unique, strong force example is the frequent travelers choice of auto rental
bargaining power of suppliers- strong force would be new car dealers who control the true price, weak force would be anyone with an oversupply who makes their own product more affordable
threat of new entrants- strong force is easy to replicate, weak is anything tightly controlled or specified.
rivalry- strong force has many other similar stores, weak force is expensive to develop and unlikely to be chosen over a main stream one
summary of competitive strategies
cost
differentiation
Industry-wide
lowest cost across industry
better product/service across the industry
focus
lowest cost within an industry segment
better product/service within an industry segment
memorize what the support activities are, primary activities are directly related to the end products.
procurement (managing supplier relationships)
procurement is the in-between of acquiring part then producing something with that
technology (investigating new designs)
producing something then shipping it requires technology
human resources (hire & support employees
shipping is only done with marketing and selling drones, which HR oversees
firm infrastructure (manage company resources)
after marketing, when sales are made we must service customers (where firm infrastructure comes in)
five primary activities
inbound logistics - receiving, storing, and disseminating inputs to the products
operations/manufacturing- transforming inputs into the final products
outbound logistics- collecting, storing, and physically distributing the products to buyers
sales and marketing- inducing buyers to purchase the products and providing means for them to do so
customer service- assisting customers use of the products and thus maintaining and enhancing products values
slide 14 and 15
ideas on how to generate competitive advantage
product implementations like creating a new one or enhancing a current products → process implementations like locking in suppliers, buyers, customers, raising barriers to enter the market, reducing costs, and establishing alliances
CHAPTER THREE
In-class activity 2 & 3 and HW 2 & 3
pivot table
dimensions = columns + rows
measures = numbers in the table
chart
regression (under data → data analysis)
for the slides (1-28)
slide 3
data, process the data for knowledge, then deliver data to employees
data includes social data, purchased data
it then is processes by business intelligence application
which is then business intelligence transferred to workers
slide 5
activities in the business intelligence process
starts with data sources (social data, purchased data, etc.)
once data is acquired we cleanse, organize and relate, then catalog
analysis on data is performed: data mining, reporting, bug data, ai, machine learning all perform analysis
then results are published: print, web servers, report serves, knowledge management systems or to content management systems
slide 7
data is stored in data warehouse (database and meta data)
before that you pre-process (or clean) the data (internal, external, and operational data)
slide 9 and 10
data warehouse is the whole company and data mart stores data
web sales data mart
store sales data mart
inventory data mart
all come from data warehouse
slide 11 and 12
summary of business intelligence techniques
reporting- create information abt past performances
process structured data by sorting, grouping summing, filtering, and formatting
data mining- classify and predict
use sophisticated statistical techniques to find patterns and relationships
big data- find patterns and relationships in big data
volume. velocity, and variety force use of MR techniques
RFM analysis
Recent - how recently a customer ordered
Frequently- how frequent
Money- how much money was spent
slide 17 and 18
unsupervised data (ex. cluster analysis)
does not use a priori hypothesis or model, findings obtained solely by data analysis
supervised data (ex. regression analysis)
uses a priori model, prediction such as the regression analysis
slide 19 and 20
The three V’s for BIG data
Huge Volume
Rapid Velocity
Great Variety
map-reduce method to handle big data
MR takes the search log and splits it into log segments where then the map phase processes and gives the reduce phase.
slide 21 and 22
Hadoop is used to process big data
open source program
manages thousands of computers
includes the query language names Pig
definition of Ai
ability of a machine to simulate human abilities such as vision, communication, recognition, learning, and decision making, in order to achieve a goal
slide 26 and 27
three stages of AI evolution
weak AI- only focuses on a single task
strong AI- equal to human intelligence for any task
super intelligence- more advanced than human intelligence
the turing test
a test of a machines ability to exhibit intelligent behavior equivalent to a human
CHAPTER FOUR
slide 3, 4, 5
what is CPU
The central processing unit is the brain of the info system
works in conjunction with main memory (RAM)
CPU reads data and instructions from memory and stores results
what is volatile and non volatile
volatile means when you exit the data is stores
non-volatile refreshes the data after every use
the types of hardware
personal computer (PC)
Tablet (including e-book readers)
Phablet
Smartphone
Server
Server Farm
slide 7
definition of “internet of things”
internet of things is the idea that objects are connected to the internet so they can interact with other devices, applications and services
slide 9, 10, 11, and 12
storage, smallest unit is 1 bit (storing one value, either 1 or 0)
1 byte = 8 bits (and other units) — remember megabyte — and petabyte (the unit for big data)
disk capacity storage is measured by terabytes, CPU speeds common unit is gigahertz
three terms of realities, and what it means
Augmented reality- alters reality by overlaying digital stuff over real world objects
Mixed reality- combines the real physical world with interactive virtual images
Virtual Reality- completely computer generated virtual world with interactive digital objects
slide 16, 17, 18
operating system and application programs for client vs server
client op system- program that control the client computer resources
client application program- application processed on client computer
server op system- program that controls the server computers resources
server application program- processed on server computer
licensing options = paid or free
license- right to use specific number of copies (fee)
site license- flat fee to install software product
open source- no license fee
horizontal application can be used by all companies,
vertical applications are for specific industries,
one-of a kind is for one institution
slide 21
remember the difference between native and web applications
as a user native applications are dependent on their operating system
web applications are independent.
