Decision Support Systems Fundamentals

The video reviews four types of decision support systems: spreadsheets, relational databases, and expert systems. It emphasizes the importance of repetition in learning and highlights the shared limitation of these systems, which is their reliance on human intervention for updates and adaptation. The video discusses how these systems require specific inputs and manual updates, contrasting with human decision-making, which evolves through experience.

What is the primary method through which we learn effectively, according to the introduction?

• Through trial and error

• By memorizing facts

• By avoiding mistakes

• Through repetition

Which type of decision support system is considered the most basic?

• Relational database

• Neural network

• Expert system

• Spreadsheet

What is a key characteristic of spreadsheets as decision support systems?

• They are complex to design

• They are the most sophisticated systems

• They can be created quickly and easily

• They require teams of programmers

What is the next level of complexity after spreadsheets in decision support systems?

• Neural networks

• Relational databases

• Machine learning models

• Decision trees

What is required to build an expert system?

• A single programmer

• A team of experts and programmers

• Only a spreadsheet

• A simple algorithm

What is a common weakness of all decision support systems discussed?

• They are not reliable

• They are too simple

• They require constant human intervention

• They are too expensive

Why do decision support systems require human intervention?

• To simplify the system

• To update and adapt to new information

• To reduce costs

• To increase complexity

What happens when new information, like weather data, is discovered?

• The system becomes obsolete

• The system needs manual updates

• The system updates automatically

• The system ignores the new data

How do humans naturally improve their decision-making skills?

• By following strict rules

• By relying on technology

• By making decisions repeatedly

• By avoiding decisions

In traditional programming, who specifies the functions a system can perform?

• The hardware

• The programmer

• The end user

• The system itself
