What is exactly a relational database?
A relational database is a type of database that organizes data into tables with rows and columns. Each table represents a different entity or concept, and the columns represent the attributes or characteristics of that entity. The tables are then related to each other through common fields, allowing for the establishment of relationships between different entities. This structure allows for efficient storage, retrieval, and manipulation of data, making relational databases a popular choice for managing large amounts of structured data in various applications. **
