Data Structure: What Is It Used for?

Data Structure What Is It Used for?

• With everything going digital nowadays, the
  amount of data being generated has also gone up.
• This has increased demand for data management
  jobs, which would require a data structures and
  algorithms training in Bangalore. 
• Data structures course online can be useful for
  app developers as well in many ways.

• A data structure is a specific format for storing
  and organizing data. Generally, types of data
  structures include the file, the array, the
  record, the tree, the record, and many more.
• A data structure is specifically designed to
  organize the data in order to suit some specific
  purpose so as to allow the user to access and
  manage the data in an appropriate manner.

• Array
• An array is a collection of elements in a precise
  order, and typically all are of same type.
• The elements can be accessed with the use of an
  integer index in order to specify the element
  that is required (depending on language being
  used, each element individually may either be of
  any type, or may be forced to be of some
  particular type).
• Typically, implementations are allocated for
  contiguous memory words for elements of the
  array, but this is not a necessity in all cases.
  Arrays could be resizable or of fixed-length.

5

• Linked list
• Linked list, or simply called list, is a
  collection of elements in a linear manner the
  linear order of which is not provided by its
  physical location in the memory.
• In linked list, each data element points to next
  element. It is a type of data structure, and
  consists of nodes that represent a sequence.
• Each node in a linked list consists of data and a
  reference (or link) to next node that comes in
  the sequence.
• This type of data structure allows an efficient
  removal and insertion of elements for various
  positions in the list sequence.
• There are certain other operations, however, that
  are slower to execute using linked list such as
  accessing randomly a certain element.

6

• Record
• A record, also known as struct or structure, is
  an aggregate and basic data structure. It is a
  collection of various fields, of different types
  of data, generally in sequence and fixed number. 
• These fields that make up a record, can also be
  known as members, specifically in programming
  that is object-oriented.
• Fields could also be known as elements however,
  it may raise confusion with elements referring to
  collection.
• The term record and tuple may or may not be used
  interchangeably, depending on the conventions,
  and the type of programming language being used.

7

• Union
• A union data type is a value which may take any
  of the several formats or representations within
  the same location in the memory or a union is a
  data structure type that is composed of a
  variable that may contain such a value as a union
  data type.
• Union types are special data types that that are
  supported by certain programming languages.
• Join online data structures and algorithms
  course to get detailed knowledge about data
  management.
