create table "table-name" -> exclude the quotes when creating the tableafter this a message will come : table created(row_name data type(limit of characters),... )for example(name varchar2(20)).This will make a column(attribute) in your table with the name "name" and data type varchar with character limit of 20.you can further add more attributes in the same manner.to insert values in the table you need this:insert into "table name" values(123,qwew,wsd,2342)the data in the brackets above depends on the attributes of your table.and now you have created a simple table.you can update, delete, alter, drop the table.

Each row on the periodic table is called a period, while each column is called a group.
