yes - columns run vertically (top to bottom) and rows run horizontally (left to right)
I don't know if you do please write it
tables
You could have 16 rows of 1 table each; or from another direction that would be 1 row of 16 tables. Or 2 rows of 8 tables each; or from another direction that would be 8 rows of two tables each. Or 4 rows of 4 tables each; which would be the same from each direction.

In databases, the main types of joins are inner join, outer join, left join, right join, and full outer join. An inner join returns only the rows with matching values in both tables, while outer joins include rows with unmatched values. A left join returns all rows from the left table and matched rows from the right, whereas a right join does the opposite. Full outer join combines the results of both left and right joins, including all rows from both tables.
No. In a database table the records are in rows and the fields are in columns.
The SELECT clause is used to retrieve rows and columns from tables. Ex: Select * from employee
In SQL, you join tables using the JOIN clause, which allows you to combine rows from two or more tables based on a related column. The most common types of joins are INNER JOIN, which returns rows with matching values in both tables; LEFT JOIN, which returns all rows from the left table and matched rows from the right table; and RIGHT JOIN, which does the opposite. You specify the joining condition using the ON keyword, typically comparing primary and foreign keys. For example: SELECT * FROM table1 INNER JOIN table2 ON table1.id = table2.foreign_id;.
It stores data in tables. Tables have rows and column. These tables are created using SQL. And data from these tables are also retrieved using SQL
spreadsheet
Both the horizontal and vertical rows in tables or matrices organize data in a systematic manner, with each row representing a different entry or category. They provide a way to compare and analyze different variables or elements across the dataset.
