A database that is based around relational model of data and, if to take into consideration the ‘visual’ explanation of such database, is represented in tables, columns and rows that relate to them. Relational database requires a pre-defined pattern (schema), according to which you can put the data pieces in such database type. You create the specific table and name it according to the data type such base is going to store. In the row section in the table, there is usually a single item term. Column in the table represents the item’s attributes (i.e. characteristics, supplementary data for the item).
