What is syntax
The set of rules (grammar)
What is semantics
Interpretation of syntax by computer
Abstraction
Hiding codes only showing important details
Representation
Specific format to show info(picture,text)
What are IS
Set of recourses to filter, store, process, create and distribute data
What is a set of recources in IS
Hardware, Software, staff, data
What are the 4 dimensions of IS
Technology, people, processes, goals
4 dimension IS: what is technology
Hardware, Software And Networks aswell as infrastructure and tools
4 dimensions is: people
Persons, communities and organisations interacting, designing and developing the system
4Dimensions of IS: what are processes
Actions and activities performed as-well as rules guiding the procedure
4 dimensions of IS: what are goals
Facts and figures aswell as the goals achieved
What is function based view ?
Marketing, human resources, finances
What is the process view
Sourcing process, recruitment process, reimbursement process
What does the IS do in a function based organisation
IS fulfills need of function and manages all relevant data
What does IS in a process based organisation do?
Ensures consistency and efficiency
Manages process relevant data
Difference between AI and regular algorithms
If a new problem occurs AI can find a solution
What are AI usage fields ?
Situation assessment, decision making
What is the implicit model
Decision making process is not defined
Leads to machine learning
What is the explicit model
Decision making process is defined by a set of rules kn which decisions are based
What are the 3 Vs of Maschine learning
Velocity, variety, volume
What is velocity
Speed at which data is processed and generated to be useful
What is variety
Different types of data are collected
What is synchronous use ?
Ability to process data in real time
What is asynchronous use
When data is collected and stored for later use (machine learning)
What is the iterative method
Repeating the same process for fine tuning
What are Accelerated information processes used for
Accelerating exciting processes by working in all data/bigger data sets giving a better understanding of single problems, better hr allocation
What is a rolling forecast ?
Forecast updated based on newest info
Used in on demand planning
What is the nimbler assessment
Checking current performance with actual performance
How can companies get data
Collected, bought, created through simulations
What is causal
Finding correlations and their causes
