  • How are tables in SQL similar to Classes and objects in OOP?
    SQL is a relational database where data is stored in tables, arranged in rows and columns format. Each table in SQL represents real-world entities or objects. For instance, if we're storing student data, we create a table named 'student' with columns such as 'name' and 'email ID'.
    We can liken these tables to classes in object-oriented programming. Classes represent real-world entities, and their properties, like 'name' and 'email' for a student, are added as variables in these classes. Objects are instances of these classes, containing actual values for these variables. For example, we can have an object for student 'Ross' with 'name' as 'Ross' and 'email' as 'ross@gmail.com'.
    So, tables in SQL are akin to classes in OOP. Attributes of classes represent their properties, similar to columns in SQL tables representing properties of tables. Objects are examples of classes containing actual values of class variables. Similarly, rows in SQL tables contain actual values of columns. For instance, one row might have 'name' as 'Ross' and 'email' as 'ross@gmail.com'.
    When developing applications, we create a table for each class, and each object's values are stored as rows in SQL tables.
