Detailed explanation-1: -A relational database is a collection of information that organizes data in predefined relationships where data is stored in one or more tables (or “relations") of columns and rows, making it easy to see and understand how different data structures relate to each other.
Detailed explanation-2: -Relational databases provide a store of related data tables. These tables have a fixed schema, use SQL (Structured Query Language) to manage data, and support ACID guarantees. No-SQL databases refer to high-performance, non-relational data stores.
Detailed explanation-3: -The relational model means that the logical data structures-the data tables, views, and indexes-are separate from the physical storage structures. This separation means that database administrators can manage physical data storage without affecting access to that data as a logical structure.
