The table is a collection of organized data in the form rows and columns. A table is the convenient representation of relations in DBMS. It is a simple form of storage.
Note: A table has to be specified with specific number of columns and it can have any number of rows

Here ‘STUDENT’ represents the Name of the Table. Name, Age, Course represents the column names. The combinations of multiple columns of data form a row. A row contains data relates to one in different columns.

The syntax of CREATE TABLE is as follows
(Column_name1 data type (size),
column_name2 data type(size),
column_name3 data type(size),
The table name specifies the name of the table
The Column_name parameter specifies the column name.
The data type Parameter here specifies what type of the data the column can hold (e.g. varchar, integer, date, etc..,)
