2. Summary • NoSQL document stores • Characteristics of document stores • MongoDB Background • Features • MongoDB demo • Questions Figure 1. Biometric authentication
3. What are NoSQL Document Stores? • NoSQL database technology designed for storing, managing and retrieving document- oriented data Mark (2019) • Examples Mongo DB, DynamoDB by AWS, Cosmos DB by Microsoft Figure 2. Document store databases
4. Characteristics • JSON-like and uses Key-value pairs • Organize records into documents and collections • CRUD Operations (Create, Read, Update and Delete) • Data Retrieval is done through APIs
5. Characteristics: JSON-like • Stores all information of an object in a single instance like a JSON object • Uses key-value pairs • Example Image has an array of customers with one customer name
