(a) The logical or mathematical model of data organization is termed as the data structure. (b) Logical or mathematical description of the structure of data (c) Implementing this structure on a computer to perform a specific task. (d) Analyzing this structure in terms of time and memory required to implement it on a machine.
In Data Structures, Data may be organized in many different ways.
therefore, the logical or mathematical model of a particular organization of data structure, The choice of a particular data model
depends on Two considerations.
First, it must be rich enough to mirror the actual relationships of the data in the real world.
another side, the structure should be simple enough that one can effectively process the data when necessary.
Therefore, The data structure can be defined as the collection of elements and all the possible
operations which are required for those set of the element.
Furthermore, another word we can say that Data Structure always will tell us which are the elements required also as well as the legal operations on those sets of elements.
Needs of Data
as a result, In Data Structures, Data is a collection of raw facts which when refined gives information.
So, it is very difficult to draw a hold line that can differentiate the two terms “Data and Information”. we can get this concept through the following Diagram.
Therefore, we can convert data into information and again information into data means it is a cyclic process.
Data that is acting as information may act as data for another person or at another level while taking the decision.
