Exam 1 Study Flashcards
Porter’s Five Forces
supplier power, buyer power, competitive rivalry, threat of substitution, threat of new entry
digitization vs. digitalization vs. digital transformation
Digitization: a business shifts from manual and paper-based ways of processing data and information to computerized approaches.
Digitalization: an organization shifts from isolated islands of digital technologies to networked and integrated technology systems
Digital transformation: an organization uses technology to critically change the way it competes as well as its internal capabilities and internal digital assets. Digital transformation leverages digital technology to radically improve, restructure, or entirely create new value to their customers.
What is DARSIL for and what are each of the steps?
to understand why they need digital transformation, what they need to improve, and how they will integrate tech
Functional requirements
what must it have to complete this task. Includes hardware & software requirements
Business requirements:
why
Design requirements:
how will a functional requirement be made to work
how are the types of requirements related
Business –> functional –> design
Functional vs non-functional requirements
functional: what it does, nonfunctional: easy/difficult/available/compatibility
strategic activities
Activities that are carried out for the future, e.g. decisions about events to happen 3 to 5 years in the future by senior- and upper-level managers
tactical activities
Activities that are carried out periodically, e.g. monthly, quarterly by employees and lower- and mid-level managers.
transactional activities
Activities that are carried out daily or weekly by employees and front-line staff
performance measures for output hardware
size, speed, quality (accuracy [resolution], brightness, sharpness)
Types of primary storage
RAM (volatile)
table fridge metaphor
table is RAM, fridge is long-term storage
Size of RAM determines:
type of OS that can run on the computer (software have minimum RAM reqs)
type of software that can run on a computer
number of software that can be concurrently opened on a laptop
Types of secondary storage
Magnetic hard drive (HDD hard disk drive), SSD solid state drive
Secondary storage
Magnetic Hard drive - devices and storage discs that hold instructions, data, software, permanently as magnetic information. Nonvolatile. Sensitive to magnetic energy
Advantages of solid state drives
no moving parts, quiet; slower write/faster read; consumes less energy, faster data access speeds, insensitivity to magnetic forces
ALU
Arithmetic & logical unit: manages the math & logic tasks
CU
control unit: manages the other tasks and softwares
Impacts of moore’s law
> faster processing of transactions
larger numbers could be processed
larger size of primary storage could be used by the CPU
multiple software applications could be run concurrently on a PC
improvement in performance/cost ratio for customers
relatively cheaper to build large computers
energy efficiency of CPUs is improved
challenges of moore’s law:
> packing pathways tightly together creates problems associated with size, heat, power (chip starts to melt when processor gets smaller)
chips can’t get smaller forever (get too small > quantum tunneling)
CPU vs GPU
gpu is graphics
Apps vs Application:
application: functional tasks- (like desktop(excel/word), functional(sales/accounting), enterprise)
apps: gaming apps, learning apps- single purpose/single function or very few functions
Features of MASs:
landing pages w CTAs, ads, social media, campaigns, lead management, web pages content designs, marketing analytics, email automation
For data to be valuable it must be
fompass
flexible organized manipulatable protected accurate searchable scalable
structured vs semistructured vs unstructured
structured: can be organized into tables
semistructured: has some structured data and some unstructured data, like an email
unstructured: like images, web pages/documents
4 operations that DBMS use to process DB:
read insert modify delete rimd
SQL databases are…
relational
distributed database
stored on multiple server computers at different locations, but that present themselves as a single
database to users
centralized database
atabase that is stored on a single machine at a
single location
cloud database
group of databases stored on servers across
different data centers and different locations
Problems With the Traditional Approach for Storing Data:
• High data redundancy
• Rigid program-data dependence
• Lack of data integrity
• High storage costs
• High data inaccuracy issues
• Lack of data integration
MAS enables orgs to support workflows for
interacting, nurturing, managing, and transforming raw leads into qualified potential customers
2 differences between SQL databases and No SQL databases
SQL is structured data, nosql is unstructured. Sql data is organized in tables
