Data structure is the logical arrangement of data element with the set of operation that is needed to access the element with a set of rules and constraint which shows the relationship that exist between individual pieces of data which may occur.
Data structure is a particular way of storing and organizing data in a computer so that it can be used efficiently. Data structure is the logical arrangement of data element with the set of operation that is needed to access the element. The logical model or mathematical model of the particular organization of data is called a data structure. It is defined as a set of rules and constraint which shows the relationship that exist between individual pieces of data which may occur.
