Goals

Knowledge/Insight
The student classifies different pre-processing methods and their applications
The student distinguishes mathematical algorithms that are needed for the implementation of IT components


Apply
The student chooses the suitable mathematical techniques, data structures and data analysis methods for the design, implementation and monitoring of IT elements, systems and solutions
The student estimates the impact of choices made in the one who comes after in working on the IT solution, the enduser, the customer, the company or society
The student formulates an advice about an IT component for an organisation

Integrate (simple)
The student chooses the appropriate storage format and technology for storing data
The student systematically uses the correct methods, technology & tools according to best practices, within the given company context
The student formulates an advice concerning a complicated IT system for a specific organisation
