Organization of table in a database : The data present in a database is organized into one or more tables. Each of table would hold a collection of related data. The data present in a table is structured into rows as well as columns. A row denotes a complete set of information regarding single item. The data stored in row is been divided into columns. Each of the columns denotes individual piece of information about item. A table has a specified number of columns, but can have any number of rows. A data type is been assigned to columns in table. The column designated as primary key holds distinctive value for each row. A primary key denotes column used for identification of a certain row in a table. An error occurs when duplicate data is been stored in primary key column.
