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. **

What is the difference between a logical data model and a relational data model?
A logical data model is a high-level representation of the data elements, their relationships, and constraints in a business domain. It focuses on the entities, attributes, and relationships between them, without considering the physical implementation. On the other hand, a relational data model is a specific implementation of a logical data model using tables, columns, and foreign key relationships in a relational database management system (RDBMS). While a logical data model is technology-agnostic and focuses on the business perspective, a relational data model is specific to the implementation in a relational database system. **

Then, you would use the SQL INSERT statement to add the new data into the table. The INSERT statement specifies the table name and the values to be inserted into the corresponding columns. Once the INSERT statement is executed, the new record will be added to the table, creating a new row with the specified data. **
