This document provides an introduction to NoSQL and MongoDB. It discusses database management systems and relational database management systems (RDBMS) that use structured query language (SQL). NoSQL databases are introduced as non-SQL alternatives that provide flexibility in data models and scaling. MongoDB is presented as a popular open-source, non-relational database that uses documents with dynamic schemas rather than tables. Key features of MongoDB like horizontal scaling, replication, and sharding are described. The document concludes with examples of CRUD operations and aggregation in MongoDB.

3. Database Management System
• A system software for creating and managing databases.
• Three main part of a DBMS:
• Data
• Database Engine
• Database Schema

4. Popular types of DBMSes
• Relational DBMSes
• Oracle
• DB2
• Microsoft SQLServer
• MySQL
• PostgreSQL
• NoSQL DBMSes
• MongoDB (Document)
• Redis (Key / Value)
• Cassandra (Column)
• Neo4j (Graph)

6. RDBMS
• A kind of DBMS that lets you
create Relational Databases
base on Relational Models.

7. RDBMS
• Uses SQL
(Structured Query
Language)

9. NoSQL
• Non SQL or Non Relational
• Other Data Model VS.
Relational Data Model
WikiPedia Definition
A NoSQL database provides a
mechanism
for storage and retrieval of data
that is modeled in means other
than the tabular relations used
in relational databases.

10. NoSQL Types

11. Why NoSQL?
• Horizontal Scaling
• Run Anywhere
• Flexible Data Model
• Faster Development
• Low Upfront Cost
• Low Cost of Ownership

13. RDBMS VS. NoSQL
Relational DBMS NoSQL DBMS
Schema Base Schema Free
Use SQL Don’t have standard query language
Vertical Scaling Horizontal Scaling
Joins No Joins
ACID
(Atomic, Consistent, Isolated, Durable)
BASE
(Basic Availability, Soft-state, Eventual consistency)
Tabular Data Model Non Tabular Data Model
(Key/Value, Document, Graph, Column)

16. MongoDB
• Comes from “humongous” /hjuːˈmʌŋɡəs/
• A scalable, high-performance, open source, schema-free,
document-oriented database
• Data is stored in JSON-like documents
• Designed with both scalability and developer agility
• Dynamic schemas

18. SQL VS. MongoDB
SQL Terms/Concepts MongoDB Terms/Concepts
Database Database
Table Collection
Row Document
Column Field
Index Index
Table joins (e.g. select queries) Embedded documents and linking
Primary keys _id field is always the primary key

19. MongoDB Features
• Document-oriented Storage
• Based on JSON
• Data serialized to BSON (type of JSON)
• Flexible Schema
• Scalable Architecture
• Replication
• High Availability
• Auto-Sharding
• Extensive use of memory mapped file
• Durable
• Strong Consistency

20. MongoDB Features
• Exclusive Features
• Full featured indexes
• Ad-hoc Query Language
• Interactive shell
• Aggregation queries
• Map / Reduce
