Exercise 2.10 - Translation between property graphs and RDF

Exercise 2.11 Identify a suitable public domain data set that contains employee, department and manager information of the sort we considered in Section 4.2. Load this data into pypopgraph and any public domain relational database, and compare their performance on the query considered in Section 4.2.

Notes on the Sample Solution

  1. The sample data was derived from the Oracle HR Schema.
  2. The HR data can be freely browsed here. The Employee, Department and EmployeementDepartment tables were constructed by posing SQL queries against the user interface provided by this portal.
  3. The performance results failed to capture the benefits of graph traversal potentially because the data size is too small. We need to do this testing on a much larger dataset especially that exceeds the available RAM.
