This document discusses different data structures and their characteristics. It defines data structures as ways of organizing data that consider the relationships between data elements. Data structures are divided into primitive and non-primitive categories. Primitive structures like integers are directly supported by programming languages, while non-primitive structures like linked lists, stacks, queues, trees and graphs are built from primitive types. Common operations on data structures include creation, selection, updating, searching, sorting, merging and deletion.

Providing Globus Services to Users of JASMIN for Environmental Data AnalysisGlobus
JASMIN is the UK’s high-performance data analysis platform for environmental science, operated by STFC on behalf of the UK Natural Environment Research Council (NERC). In addition to its role in hosting the CEDA Archive (NERC’s long-term repository for climate, atmospheric science & Earth observation data in the UK), JASMIN provides a collaborative platform to a community of around 2,000 scientists in the UK and beyond, providing nearly 400 environmental science projects with working space, compute resources and tools to facilitate their work. High-performance data transfer into and out of JASMIN has always been a key feature, with many scientists bringing model outputs from supercomputers elsewhere in the UK, to analyse against observational or other model data in the CEDA Archive. A growing number of JASMIN users are now realising the benefits of using the Globus service to provide reliable and efficient data movement and other tasks in this and other contexts. Further use cases involve long-distance (intercontinental) transfers to and from JASMIN, and collecting results from a mobile atmospheric radar system, pushing data to JASMIN via a lightweight Globus deployment. We provide details of how Globus fits into our current infrastructure, our experience of the recent migration to GCSv5.4, and of our interest in developing use of the wider ecosystem of Globus services for the benefit of our user community.

Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.

2. Data : simply a value of some data type like integer,
character etc.
Structure: way of organizing or storing data
Data structure is a way of organizing all data items
that considers not only the elements stored but also
their relationship to each other.
3. Program=algorithm + Data Structure
You know that a algorithm is a step by step procedure
to solve a particular function.
4. That means, algorithm is a set of instruction written
to carry out certain tasks & the data structure is the
way of organizing the data with their logical
relationship retained.
To develop a program of an algorithm, we should
select an appropriate data structure for that algorithm.
Therefore algorithm and its associated data structures
from a program.
5. Data structure are normally divided into two broad
categories:
◦ Primitive Data Structure
◦ Non-Primitive Data Structure
8. There are basic structures and directly operated upon
by the machine instructions.
In general, there are different representation on
different computers.
Integer, Floating-point number, Character constants,
string constants, pointers etc, fall in this category.
9. There are more sophisticated data structures.
These are derived from the primitive data structures.
The non-primitive data structures emphasize on
structuring of a group of homogeneous (same type) or
heterogeneous (different type) data items.
10. Lists, Stack, Queue, Tree, Graph are example of non-
primitive data structures.
The design of an efficient data structure must take
operations to be performed on the data structure.
11. The most commonly used operation on data
structure are broadly categorized into following
types:
◦ Create
◦ Selection
◦ Updating
◦ Searching
◦ Sorting
◦ Merging
◦ Destroy or Delete
12. A primitive data structure is generally a basic structure
that is usually built into the language, such as an
integer, a float.
A non-primitive data structure is built out of primitive
data structures linked together in meaningful ways,
such as a or a linked-list, binary search tree, AVL Tree,
graph etc.
13. An array is defined as a set of finite number of
homogeneous elements or same data items.
It means an array can contain one type of data only,
either all integer, all float-point number or all
character.
14. Simply, declaration of array is as follows:
int arr[10]
Where int specifies the data type or type of elements
arrays stores.
“arr” is the name of array & the number specified
inside the square brackets is the number of elements
an array can store, this is also called sized or length
of array.
15. Following are some of the concepts to be remembered
about arrays:
◦ The individual element of an array can be
accessed by specifying name of the array,
following by index or subscript inside square
brackets.
◦ The first element of the array has index
zero[0]. It means the first element and last
element will be specified as:arr[0] & arr[9]
Respectively.
16. ◦ The elements of array will always be stored
in the consecutive (continues) memory
location.
◦ The number of elements that can be stored
in an array, that is the size of array or its
length is given by the following equation:
(Upperbound-lowerbound)+1
17. ◦ For the above array it would be
(9-0)+1=10,where 0 is the lower bound of
array and 9 is the upper bound of array.
◦ Array can always be read or written through
loop. If we read a one-dimensional array it
require one loop for reading and other for
writing the array.
18. ◦ For example: Reading an array
For(i=0;i<=9;i++)
scanf(“%d”,&arr[i]);
◦ For example: Writing an array
For(i=0;i<=9;i++)
printf(“%d”,arr[i]);
19. ◦ If we are reading or writing two-dimensional
array it would require two loops. And
similarly the array of a N dimension would
required N loops.
◦ Some common operation performed on array
are:
Creation of an array
Traversing an array
20. ◦ Insertion of new element
◦ Deletion of required element
◦ Modification of an element
◦ Merging of arrays
21. A lists (Linear linked list) can be defined as a
collection of variable number of data items.
Lists are the most commonly used non-primitive data
structures.
An element of list must contain at least two fields, one
for storing data or information and other for storing
address of next element.
As you know for storing address we have a special data
structure of list the address must be pointer type.
22. Technically each such element is referred to as a node,
therefore a list can be defined as a collection of nodes
as show bellow:
Head
AAA BBB CCC
Information field Pointer field
[Linear Liked List]
23. Types of linked lists:
◦ Single linked list
◦ Doubly linked list
◦ Single circular linked list
◦ Doubly circular linked list
24. A stack is also an ordered collection of elements like
arrays, but it has a special feature that deletion and
insertion of elements can be done only from one end
called the top of the stack (TOP)
Due to this property it is also called as last in first out
type of data structure (LIFO).
25. It could be through of just like a stack of plates placed on
table in a party, a guest always takes off a fresh plate
from the top and the new plates are placed on to the stack
at the top.
It is a non-primitive data structure.
When an element is inserted into a stack or removed
from the stack, its base remains fixed where the top of
stack changes.
26. Insertion of element into stack is called PUSH and
deletion of element from stack is called POP.
The bellow show figure how the operations take place
on a stack:
PUSH POP
[STACK]
27. The stack can be implemented into two ways:
◦ Using arrays (Static implementation)
◦ Using pointer (Dynamic implementation)
28. Queue are first in first out type of data structure (i.e.
FIFO)
In a queue new elements are added to the queue from
one end called REAR end and the element are always
removed from other end called the FRONT end.
The people standing in a railway reservation row are
an example of queue.
29. Each new person comes and stands at the end of
the row and person getting their reservation
confirmed get out of the row from the front end.
The bellow show figure how the operations take
place on a stack:
10 20 30 40 50
front rear
30. The queue can be implemented into two ways:
◦ Using arrays (Static implementation)
◦ Using pointer (Dynamic implementation)
31. A tree can be defined as finite set of data items (nodes).
Tree is non-linear type of data structure in which data
items are arranged or stored in a sorted sequence.
Tree represent the hierarchical relationship between
various elements.
32. In trees:
There is a special data item at the top of hierarchy
called the Root of the tree.
The remaining data items are partitioned into number
of mutually exclusive subset, each of which is itself,
a tree which is called the sub tree.
The tree always grows in length towards bottom in
data structures, unlike natural trees which grows
upwards.
33. The tree structure organizes the data into branches,
which related the information.
A
B C
D E F G
root
34. Graph is a mathematical non-linear data structure
capable of representing many kind of physical
structures.
It has found application in Geography, Chemistry and
Engineering sciences.
Definition: A graph G(V,E) is a set of vertices V and a
set of edges E.
35. An edge connects a pair of vertices and many have
weight such as length, cost and another measuring
instrument for according the graph.
Vertices on the graph are shown as point or circles and
edges are drawn as arcs or line segment.
