Consider the relational schema below: Students (sid: integer, sname: string, major: string) Courses (cid: integer, cname: string, hours: integer) Enrollment (sid: integer, cid: integer, grade: real) Write a relational algebra expression that satisfies this query? Find the distinct names of all students that take at least three courses and major in "Philosophy".

Padgett's data on marriage alliances among leading Florentine families in the latter Renaissance is given in the Figure below. Each node represents a family, and each edge denotes a connection through marriage. Load the data as a Neo4j Knowledge Graph. For each node, compute and interpret the following measures of centrality: Degree Centrality, Closeness Centrality, Betweenness Centrality, Eigenvector Centrality, PageRank. Apply Neo4j Bloom or Python NetworkX to visualize your insights. Your quantitative and visual insights should be presented in your CA01 Report.
Write the following queries in relational algebra, using the university schema. a. Find the titles of courses in the Comp. Sci. department that have 3 credits. b. Find the IDs of all students who were taught by an instructor named Einstein; make sure there are no duplicates in the result. c. Find the highest salary of any instructor. d. Find all instructors earning the highest salary (there may be more than one with the same salary). e. Find the enrollment of each section that was offered in Autumn 2009. f. Find the maximum enrollment, across all sections, in Autumn 2009. g. Find the sections that had the maximum enrollment in Autumn 2009.
