Unified Modeling Language (UML) is a general purpose modelling language. The main aim of UML is to define a standard way to visualize the way a system has been designed. It is quite similar to blueprints used in other fields of engineering.
UML is not a programming language, it is rather a visual language. We use UML diagrams to portray the behavior and structure of a system. UML helps software engineers, businessmen and system architects with modelling, design and analysis. The Object Management Group (OMG) adopted Unified Modelling Language as a standard in 1997. Its been managed by OMG ever since. International Organization for Standardization (ISO) published UML as an approved standard in 2005. UML has been revised over the years and is reviewed periodically.

Why React Native as a Strategic Advantage for Startup Innovation.pdfayushiqss
Do you know that React Native is being increasingly adopted by startups as well as big companies in the mobile app development industry? Big names like Facebook, Instagram, and Pinterest have already integrated this robust open-source framework.
In fact, according to a report by Statista, the number of React Native developers has been steadily increasing over the years, reaching an estimated 1.9 million by the end of 2024. This means that the demand for this framework in the job market has been growing making it a valuable skill.
But what makes React Native so popular for mobile application development? It offers excellent cross-platform capabilities among other benefits. This way, with React Native, developers can write code once and run it on both iOS and Android devices thus saving time and resources leading to shorter development cycles hence faster time-to-market for your app.
Let’s take the example of a startup, which wanted to release their app on both iOS and Android at once. Through the use of React Native they managed to create an app and bring it into the market within a very short period. This helped them gain an advantage over their competitors because they had access to a large user base who were able to generate revenue quickly for them.

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.

1. Object Diagram :
It is a diagram that shows a set of objects and their relationships at a
point in time.
Graphically, an object diagram is a collection of vertices and arcs.
Common Properties :
An object diagram is a special kind of diagram and shares the same
common properties as all other diagrams that is,
1. name and
2. graphical contents that are a projection into a model.
What distinguishes an object diagram from all other kinds of diagrams ?
It is its particular content.
1
Object Diagrams : Terms & Concepts
2. Contents :
Object diagrams commonly contain
1. Objects 2. Links
Like all other diagrams, object diagrams may contain notes & constraints.
Note : Sometimes you'll want to place classes in your object diagrams as well,
especially when you want to visualize the classes behind each instance.
Note : Object diagram correlates with a class diagram.
Class diagram : It describes the general situation and the instance diagram
describes specific instances derived from the class diagram.
Object diagram : contains primarily objects and links.
Note : Deployment diagrams may also occur in generic and instance forms.
General deployment diagrams describe node types.
Instance deployment diagrams describe a concrete configuration of node
instances described by those types.

Object Diagrams : Terms & Concepts
3. Object Diagrams : Common Modeling Techniques
To model an Object structure :
1. Identify the mechanism you'd like to model. A mechanism represents some
function or behavior of the part of the system you are modeling that results
from the interaction of a society of classes, interfaces, and other things.
2. Create a collaboration to describe a mechanism.
3. For each mechanism, identify the classes, interfaces, and other elements
that participate in this collaboration; identify the relationships among these
things as well.
4. Consider one scenario that walks through this mechanism. Freeze that
scenario at a moment in time, and render each object that participates in
the mechanism.
5. Expose the state and attribute values of each such object, as necessary, to
understand the scenario.
6. Similarly, expose the links among these objects, representing instances of
associations among them. 3
4. As this figure indicates, one object represents the robot itself (r, an
instance of Robot), r is currently in the state marked moving. This object
has a link to w, an instance of World, which represents an abstraction of
the robot's world model.
4
At this moment in time, w is linked to two
instances of Area. One of them (a2) is
shown with its own links to three Wall
objects and one Door object. Each of these
walls is marked with its current width, and
each is shown linked to its neighboring
walls.
As this object diagram suggests, the robot
has recognized this enclosed area, which
has walls on three sides and a door on the
fourth.
Object Diagrams : Common Modeling Techniques
5. Reverse Engineering : To reverse engineer an object diagram,
1. Chose the target you want to reverse engineer. Typically, you'll set your context
inside an operation or relative to an instance of one particular class.
2. Using a tool or simply walking through a scenario, stop execution at a certain
moment in time.
3. Identify the set of interesting objects that collaborate in that context and render them
in an object diagram.
4. As necessary to understand their semantics, expose these object's states.
5. As necessary to understand their semantics, identify the links that exist among these
objects.
6. If your diagram ends up overly complicated, prune it by eliminating objects that are
not germane to the questions about the scenario you need answered. If your
diagram is too simplistic, expand the neighbors of certain interesting objects and
expose each object's state more deeply.
7. You will usually have to manually add or label structure that is not explicit in the
target code. The missing information supplies the design intent that is only implicit in
the final code.
5
Object Diagrams : Common Modeling Techniques
6. Object Diagrams : Hints & Tips
A well-structured object diagram
1. Is focused on communicating one aspect of a system's static design view
or static process view.
2. Represents one frame in the dynamic storyboard represented by an
interaction diagram.
3. Contains only those elements that are essential to understanding that
aspect.
4. Provides detail consistent with its level of abstraction; you should expose
only those attribute values and other adornments that are essential to
understanding.
5. Is not so minimalist as to misinform the reader about semantics that are
important.
6
7. Object Diagrams : Hints & Tips
When you draw an object diagram,
1. Give it a name that communicates its purpose.
2. Lay out its elements to minimize lines that cross.
3. Organize its elements spatially so that things that are semantically close
are laid out to be physically close.
4. Use notes and color as visual cues to draw attention to important features
of your diagram.
5. Include the values and state of each object as necessary to communicate
your intent.
