could be easily processed. All this necessary data could most likely be found in a relational database that the store uses to efficiently run all the necessary transactions. In this database, all the data is collected and grouped into different pockets or tables that better categorize the information. Through the relationships created between the tables,

Summary: Database Management System in easy terms we can say that set of data organized in a relative way. It allows data for various entries, storage and retrieval of large quantity of information and provides ways to manage how the information is stored. There is big number of database providers and each different database has its own strength so while choosing a particular database we need to understand what the business requirement is and match them with what DBMS can provide us to make our
