10 different between SQL and No SQL

10 different between SQL and No SQL

SQL databases use a relational data model, where data is organized into tables with predefined relationships between them, while NoSQL databases use a variety of data models, such as document-based, key-value, and graph.

Data Model

Data Model

SQL databases require a predefined schema to be created before data can be stored, while NoSQL databases are schema-less, allowing for flexible and dynamic data structures.

Title 2

SQL databases are vertically scalable, meaning they can only be scaled up by adding more processing power or memory to a single machine, while NoSQL databases are horizontally scalable, meaning they can be distributed across multiple servers to handle increasing amounts of data.

Query Language

Query Language

SQL databases use SQL (Structured Query Language) to retrieve and manipulate data, while NoSQL databases use various query languages specific to their data models, such as MongoDB's query language for document-based databases

Transactions

Transactions

SQL databases support ACID (Atomicity, Consistency, Isolation, Durability) transactions, ensuring data consistency and reliability, while NoSQL databases often sacrifice ACID properties for scalability and performance.

Joins:

Joins:

SQL databases support joins between tables to combine related data, while NoSQL databases typically denormalize data to avoid the need for complex joins.

  Data Integrity

  Data Integrity

SQL databases have built-in mechanisms to enforce data integrity through constraints, such as unique and foreign key constraints, while NoSQL databases typically do not have such constraints.

Schema Changes

Schema Changes

SQL databases require schema changes to be made before data can be added or removed, while NoSQL databases allow for dynamic changes to data structures without needing to modify the schema.

SQL databases have a limited storage capacity due to their relational data model and strict schema requirements, while NoSQL databases can store massive amounts of data with ease due to their flexible data models and schema-less nature.
