Study Notes
SQL, NoSQL, and NewSQL
- SQL, NoSQL, and NewSQL are different types of databases
- NoSQL databases can be classified into four types: Columnar Database, Key-Value Stores, Document Stores, and Graph Database
MongoDB
- MongoDB is a NoSQL, open source, document-oriented database designed for scalability and developer agility
- It stores data in JSON-like documents with dynamic schemas (schema-free, schemaless)
- MongoDB bridges the gap between key-value stores (fast and scalable) and relational databases (rich functionality)
MongoDB Goals
- Horizontal scaling out
- Query Routers (mongos)
- Shard keys: range based sharding, cardinality, and avoiding hotspotting
Data Model
- BSON format (binary JSON) for storing data
- Lightweight, traversable, and efficient
- Easy to map to modern object-oriented languages without a complicated ORM layer
MongoDB Model
- A document is a single unit of data (like a tuple in RDBMS)
- A collection is a group of similar documents
- Each document in a collection must have a unique Id
- Field names cannot start with the $ character or contain the . character
MongoDB Architecture
- MongoDB is a distributed document database
NoSQL Data Services
- Document Datastores
- MongoDB Architecture
- Distributed Models in MongoDB
- Document Schemas and CRUD Operations
- Cloud Services for MongoDB
- Lab Practice – Working with MongoDB
This quiz covers NoSQL data services, including MongoDB, and types of NoSQL databases such as columnar databases and key-value stores. It's a part of the Medical Distributed Application Development course.
