RDBMS is the basis for SQL, and for all modern database systems such as MS SQL Server, IBM DB2, Oracle, MySQL, and Microsoft Access. The data in RDBMS is stored in database objects called tables. A table is a collection of related data entries and it consists of columns and rows. Look at the "Customers" table:
SELECT * FROM Customers;
The columns in the "Customers" table consist of CustomerID, CustomerName, ContactName, Address,City, PostalCode and Country. A column is a vertical entity in a table. A record, also called a row, is each individual entry that exists in a table. For example, there are 91 records in the above Customers table. A record is a horizontal entity in a table.
