Data structure is the representation of the logical relationship existing between individual elements of data. In other words the data structure is a way of organizing all data items that considers not only the elements stored but also their relationship to each other.

Data structure specifies

 Organization of data

 Accessing methods

 Degree of associativity

 Processing alternatives for information

The data structures are the building blocks of a program and hence the selection of a particular data structure stresses on

 The data structures must be rich enough in structure to reflect the relationship existing between the data, and

 The structure should be simple so that we can process data effectively whenever required.

In mathematically Algorithm + Data Structure = Program

Finally we can also define the data structure as the “Logical and mathematical model of a particular organization of data”
