Construct conceptual models for the following types of graphs- using E.pdf
0 likes16 views
The document outlines the construction of conceptual models using entity-relationship (ER) diagrams for three types of graphs: directed graphs, hypergraphs, and multigraphs. It describes directed graphs as consisting of nodes with directed edges, hypergraphs as having nodes connected by hyperedges with multiple sources and a single target, and multigraphs featuring multiple undirected edges between the same pair of nodes. Each conceptual model requires a sample graph to illustrate its population.

Construct conceptual models for the following types of graphs- using E.pdf
- 1. Construct conceptual models for the following types of graphs, using ER (Entity-Relationship) Diagrams: 1. directed graphs Directed graphs consist of nodes and directed edges be- tween nodes. 2. hypergraphs Hypergraphs consist of nodes and hyperedges between these nodes. A hyperedge has multiple (at least one) sources and a single target. 3. multigraphs Multigraphs consist of nodes and undirected edges between these nodes. As opposed to undirected graphs, there may be multiple edges between the same pair of nodes. For each of your conceptual models create a sample graph and show this graph as a population of your model.
