NoSQL

✅ NoSQL

unrelational DB not only SQL

• can use query language depending on API/DB/query

• 👍🏻 scalability
• 👍🏻 availability
• 👍🏻 data is saved according to how application is used
• 👍🏻 need for data encoding ⬇️
• 👍🏻 cloud environment: no downtime
• 🛠️ used in in-time application
• 🛠️ bigdata

🆚 RDB

RDB: Relational Database

✔️ NoSQL

• Data Modeling: more difficult than relational DB
• Scalability: ⬆️
• Relational: no relation
• Transaction: 👎🏻
• 👍🏻 more flexible
• 👍🏻 fast operation
• 👍🏻 big data

✔️ RDB

• Data Modeling: table ➕ key-value ➕ constraints
• Scalability:
• Relational: data based on relation
• Transaction: 👍🏻
• 👎🏻 big data
• 👎🏻 slower than NoSQL

❓ Why is NoSQL faster than RDB?

• NoSQL does not have constraints nor schema

• not structured DB

• thus, add, update, delete data is faster
• efficient in handling big data
• high scalability
• more flexible
