PSEQUEL OPTIONS FOR WINDOWS HOW TOLet's consider how to store the same information about a user and their hobbies in a document database like MongoDB.Psql -host=. -port=5432 -username=awsuser -password -dbname=mypgdb Connecting with the AWS JDBC Driver for PostgreSQL The data model we design for a NoSQL database will depend on the type of NoSQL database we choose. In order to retrieve all of the information about a user and their hobbies, information from the Users table and Hobbies table will need to be joined together. In a relational database, we'd likely create two tables: one for Users and one for Hobbies. We need to store a user's first name, last name, cell phone number, city, and hobbies. Let's consider an example of storing information about a user and their hobbies. Then, we'll highlight some of the other key differences between relational databases and NoSQL databases. In this section, we'll work through an example of modeling the same data in a relational database and a NoSQL database. ![]() While a variety of differences exist between relational database management systems (RDBMS) and NoSQL databases, one of the key differences is the way the data is modeled in the database. Difference between RDBMS and NoSQL databases To learn more, visit Understanding the Different Types of NoSQL Databases. Nodes typically store information about people, places, and things, while edges store information about the relationships between the nodes. Graph databases store data in nodes and edges.Wide-column stores store data in tables, rows, and dynamic columns.Key-value databases are a simpler type of database where each item contains keys and values.The values can typically be a variety of types including things like strings, numbers, booleans, arrays, or objects. ![]() Each document contains pairs of fields and values.
