A relational database is a database that uses tables, rows, and columns to store and organize data. It follows a structured process called normalization to minimize redundancy and ensure data integrity. It enforces predefined relationships between tables using primary and foreign keys. It uses SQL (Structured Query Language) to manipulate and query the data.
On the other hand, a NoSQL database is a non-relational database that does not follow the traditional table structure. It can store data in a variety of formats such as key-value pairs, documents, graphs, or wide-column stores. It does not enforce strict relationships between data entities. NoSQL databases are designed to handle unstructured or semi-structured data, such as JSON or XML, and can scale horizontally by distributing data across multiple servers.
In summary, the main differences between a relational database and a NoSQL database are the data structure they use, the enforcement of relationships, and the format in which data is stored. Relational databases store structured data in tables with predefined relationships and use SQL, while NoSQL databases store unstructured or semi-structured data in various formats and do not enforce strict relationships.
