A data structure is a specialized format for organizing, processing, retrieving and storing data. There are several basic and advanced types of data structures, all designed to arrange data to suit a specific purpose. Data structures make it easy for users to access and work with the data they...
Array data Structure Representation Note: Data structure and data types are slightly different. Data structure is the collection of data types arranged in a specific order. Types of Data Structure Basically, data structures are divided into two categories: Linear data structure Non-linear data struc...
Data preparation is the process of getting well formatted data into a single table or multiple related tables so it can be analyzed in Tableau. This includes both the structure, i.e. rows and columns, as well as aspects of data cleanliness, such correct data types and correct data values....

Data structurescan be defined as the organization of data in a logical or mathematical model. It must be simple enough that one can effectively process the data when necessary [1]. The data present in the data structure are processed using several operations, which are described as follows. ...
Following are the 17 different types of graph in the data structure explained below. 1. Finite Graph A graph G= (V, E) in case the number of vertices and edges in the graph is finite in number. 2. Infinite Graph A graph G=(V, E) is said to infinite if the number of edges and...
Typically, you use structure types to design small data-centric types that provide little or no behavior. For example, .NET uses structure types to represent a number (bothintegerandreal), aBoolean value, aUnicode character, atime instance. If you're focused on the behavior of a type, consi...
