Prepare tables and data:
<标题>1.Download Assign-3-create-tables.sql, Assign-3-insert-data.sql, and Assign-3-delete-tables.sql from ANGEL->Solutions->Homework Assignment 3 Solution
2.Delete the tables you have created for Assignment 3-1 in your database usingAssign-3-delete-tables.sql
<标题>You are required to develop a web based matching system, for example matching of jobs required by employers to skills of potential employees,

<标题>In this assignment, you will show that you can work with different NoSQL systems for
data persistence and understand the strength and weakness of each system with respect to
<标题>certain workload features. You are asked to work with a music data set and a list of target
queries. You will design data schema based on the data set feature and the given query
workload for MongoDB, Neo4j and HBase respectively. You will show that your design can
<标题>support the target queries by load the data in each system following your schema and run
queries against the data.
