VECTOR DATA STRUCTURE: The vector representation of an object is an attempt to represents the object as exactly as possible. The coordinate space is assumed to . unordered_map uses hash table. Same procedure, but replace map with unordered_map on the code. This makes sense, since std::unordered_map cannot be traversed in order, so the standard library chose hash map instead of Red-black tree, since hash map has a better amortized insert time complexity. Topology rules can help data integrity with vector data models. Not only that, network analysis and proximity operations use vector data structures. What are disadvantages of using vector data? Continuous data is poorly stored and displayed as vectors. In order to display continuous data as a vector, it would require substantial generalization.
