Answer to Question 1

Based on mathematical graph theory, graph databases are composed of nodes, properties and edges. Nodes are equivalent to entities in E-R data modeling and tables (or relations) in database design. They represent the things that we want to keep track of or about which we want to store data. Properties are equivalent to attributes in E-R data modeling and columns (or fields) in database design. They represent the data items that we want to store for each node. Edges are similar to, but not identical to, the relationships in E-R data models and database designs. They are similar because they connect nodes as relationships connect entities, but they are different because they also store data. Edges can be one-way or two-way.

Answer to Question 2

FALSE
