The Unified Modeling Language (UML) has become the de-facto standard for building
Object-Oriented software. UML 2.1 builds on the already highly successful UML 2.0
standard, which has become an industry standard for modeling, design and construction
of software systems as well as more generalized business and scientific processes.
UML 2.1 defines thirteen basic diagram types, divided into two general sets: structural
modeling diagrams and behavioral modeling diagrams. Part one will deal with
structural modeling diagrams.
The objective is to explain how a software design may be represented as a set of interacting objects that manage their own state and operations and to introduce various models that describe an object-oriented design.

Understanding Globus Data Transfers with NetSageGlobus
NetSage is an open privacy-aware network measurement, analysis, and visualization service designed to help end-users visualize and reason about large data transfers. NetSage traditionally has used a combination of passive measurements, including SNMP and flow data, as well as active measurements, mainly perfSONAR, to provide longitudinal network performance data visualization. It has been deployed by dozens of networks world wide, and is supported domestically by the Engagement and Performance Operations Center (EPOC), NSF #2328479. We have recently expanded the NetSage data sources to include logs for Globus data transfers, following the same privacy-preserving approach as for Flow data. Using the logs for the Texas Advanced Computing Center (TACC) as an example, this talk will walk through several different example use cases that NetSage can answer, including: Who is using Globus to share data with my institution, and what kind of performance are they able to achieve? How many transfers has Globus supported for us? Which sites are we sharing the most data with, and how is that changing over time? How is my site using Globus to move data internally, and what kind of performance do we see for those transfers? What percentage of data transfers at my institution used Globus, and how did the overall data transfer performance compare to the Globus users?
In software engineering, the right architecture is essential for robust, scalable platforms. Wix has undergone a pivotal shift from event sourcing to a CRUD-based model for its microservices. This talk will chart the course of this pivotal journey.
Event sourcing, which records state changes as immutable events, provided robust auditing and "time travel" debugging for Wix Stores' microservices. Despite its benefits, the complexity it introduced in state management slowed development. Wix responded by adopting a simpler, unified CRUD model. This talk will explore the challenges of event sourcing and the advantages of Wix's new "CRUD on steroids" approach, which streamlines API integration and domain event management while preserving data integrity and system resilience.
Participants will gain valuable insights into Wix's strategies for ensuring atomicity in database updates and event production, as well as caching, materialization, and performance optimization techniques within a distributed system.
Join us to discover how Wix has mastered the art of balancing simplicity and extensibility, and learn how the re-adoption of the modest CRUD has turbocharged their development velocity, resilience, and scalability in a high-growth environment.
How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.

First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.

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.

Informed by our team’s work in applying high-performance computing in support of public health decision makers during the COVID-19 pandemic, we present how Globus technologies are enabling the development of an open science platform for robust epidemic analysis, with the goal of collaborative, secure, distributed, on-demand, and fast time-to-solution analyses to support public health.
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.
2. 2
System development refers to all activities that go into
producing information system solution.
System development activities consist of system
analysis, modeling, design, implementation, testing and
maintenance.
Object-Oriented (OO) systems development is a way to
develop software by building self-contained modules
that can be more easily:
Replaced
Modified
and Reused.
3. 3
A software system is a set of mechanism for performing
certain action on certain data.
Algorithm + Data structure = Program
4. 4
The code is subdivided into modules
Each module is made of procedures and data structures
Procedures operate on data, e.g. modifying them
e.g. the “C” programming language
There is no strong connection between procedures
Every procedure may possibly access any data and modify
it and data
5. 5
OO approach is more like creating a lot of helpers that
take on an active role, a spirit, that form a community
whose interactions become the application.
Models the problem to be solved as a set of interacting
objects, each carrying its own state and exhibiting its
own behavior
By separating concerns, this approach has proved to be
robust and useful to solve more complex programming
problems.
6. 6
The physical world is made of a set of objects that can
interact
Each of them presents
An identity (objects can be recognized)
A state (objects remember their history)
A behavior (objects react to external stimuli in a
predictable way)
7. 7
Faster development,
Increased quality
Raising the level of abstraction.
It adapts to
Changing requirements
Easier to maintain
More robust
Promote greater design
Code reuse
8. 8
Goals:
Define Objects and classes
Describe objects‘ methods, attributes and how objects
respond to messages,
Define Polymorphism, Inheritance, data abstraction,
encapsulation, and protocol,
Describe objects relationships,
Describe object persistence.
Understand meta-classes.
9. 9
The term object was first formally utilized in the Similar
language to simulate some aspect of reality.
An object is an entity.
It knows things (has attributes)
It does things (provides services or has methods)
Note:
Attributes or properties represented by data type and
describe object‘s state (data)
Methods define objects behavior and specify the way in
which an Object‘s data are manipulated.
10. 10
It Knows things (attributes)
I am an Employee.
I know my name, social security number and my address.
Attributes
I am a Car.
I know my color,
manufacturer, cost,
owner and model.
It does things (methods)
I know how to compute my payroll.
11. 11
In an object-oriented system, everything is an object:
numbers, arrays, records, fields, files, forms, an
invoice, etc.
An Object is anything, real or abstract, about which we
store data and those methods that manipulate the data.
Conceptually, each object is responsible for itself.
A window object is responsible for things like opening,
sizing, and closing itself.
12. 12
When developing an O-O application, two basic
questions always arise.
What objects does the application need?
What functionality should those objects have?
14. 14
Represent named properties of a UML class
UML class can have many attributes of different names
Attribute name is generally a short noun or a noun
phrase written in lowerCase-first text
Attribute declaration may include visibility, type and
initial value: +attributeName : type = initial-value
15. 15
Represent named services provided by a UML class
UML class can have many operations of different
names
Operation name is generally a short verb or a verb
phrase written in lowerCase-first text
Operation may include visibility, parameters, and
return type: +opName(param1 : type = initial_value)
: return-type
16. 16
Three levels of class, attribute and operation visibility:
• private (-), available only to the current class
• protected (#), available to the current and inherited
classes
• public (+), available to the current and other classes
17. 17
Each class represents a set of objects that share the
same attributes, operations, relationships, and
semantics
For each of the class attributes, objects can have
specific attribute values
For each of the class operations, objects may have
different implementations
18. 18
Represent a relation between a parent (a more abstract
class) and a child (a more specific class)
Generally referred to as a “is-a-kind-of” relationship
Child objects may be used instead of parent objects
since they share attributes and operations; the opposite
is not true
19. 19
An object-oriented system organizes classes into
subclass-super hierarchy.
At the top of the hierarchy are the most general classes
and at the bottom are the most specific
A subclass inherits all of the properties and methods
(procedures) defined in its super class.
20. 20
Inheritance is a relationship between classes where one
class is the parent class of another (derived) class.
Inheritance allows classes to share and reuse behaviors
and attributes.
The real advantage of inheritance is that we can build
upon what we already have and,
Reuse what we already have.
23. 23
OO systems permit a class to inherit from more than
one superclass.
24. 24
Information hiding is a principle of hiding internal data
and procedures of an object.
By providing an interface to each object in such a way
as to reveal as little as possible about its inner
workings.
Encapsulation protects the data from corruption.
25. 25
Objects perform operations in response to messages.
For example, you may communicate with your
computer by sending it a message from hand-help
controller.
26. 26
Consider a payroll program that processes employee
records at a small manufacturing firm. This company
has three types of employees:
Managers: Receive a regular salary.
Office Workers: Receive an hourly wage and are eligible
for overtime after 40 hours.
Production Workers: Are paid according to a piece rate.
27. 27
Structured Approach
FOR EVERY EMPLOYEE DO
BEGIN
IF employee = manager THEN
CALL computeManagerSalary
IF employee = office worker THEN
CALL computeOfficeWorkerSalary
IF employee = production worker THEN
CALL computeProductionWorkerSalary
END
34. 34
The concept of association represents relationships
between objects and classes. For example a pilot can
fly planes
Association can be binary, between two classes, or n-
ary, among more than two classes
Can include association name, direction, role names,
multiplicity, and aggregation type
35. 35
Represent a specific, whole/part structural relationship
between class objects
Composition [is entirely made of]: (closed diamond)
represents exclusive relationship between two class
objects (e.g., a faculty cannot exist without nor be a part
of more than one university)
Aggregation [is part of]: (open diamond) represents
nonexclusive relationship between two class objects (e.g.,
a student is a part of one or more faculties)
36. 36
Objects have a lifetime. An object can persist beyond
application session boundaries, during which the object
is stored in a file or a database, in some file or database
form.
37. 37
Everything is an object.
How about a class?
Is a class an object?
Yes, a class is an object! So, if it is an object, it must
belong to a class.
Indeed, class belongs to a class called a Meta-Class or
a class' class.
Meta-class used by the compiler. For example, the
meta-classes handle messages to classes, such as
constructors and "new.“
