Study Notes
Databases and Modelling
- Databases involve tables and queries
- Modelling and simulation involve abstraction of reality
- OOP involves classes and sub-classes
- Web science involves distributed applications
Computational Thinking and Program Design
- Abstraction involves successive decomposition (e.g., school -> faculties -> departments)
- Real-world entities can be distinguished from their abstractions (e.g., map vs. territory)
Standard Algorithms
- Characteristics of standard algorithms on linear arrays include:
- Sequential search
- Binary search
- Bubble sort
- Selection sort
- Standard operations of collections include:
- Addition
- Retrieval of data
Algorithms and Problem-Solving
- Algorithms can be used to solve specific problems
- Differences between algorithms include:
- Advantages and disadvantages of using binary search vs. sequential search
- Examples of algorithms include:
- Reversing the contents of an array (e.g., NAMES)
- Searching an array (e.g., CITYNAMES) for specific elements (e.g., cities starting with "D")
