The class diagram shows the key classes and relationships in a school information modeling system. The main classes are School, Department, Subject, Student, and Instructor. A school has departments and a department offers subjects. A student can enroll in up to 5 subjects and an instructor can teach up to 3 subjects. An instructor is assigned to one or more departments. The class diagram also shows the relationships between these classes such as a student attending a school and taking subjects, and an instructor teaching subjects.

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.

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.

Innovating Inference - Remote Triggering of Large Language Models on HPC Clus...Globus
Large Language Models (LLMs) are currently the center of attention in the tech world, particularly for their potential to advance research. In this presentation, we'll explore a straightforward and effective method for quickly initiating inference runs on supercomputers using the vLLM tool with Globus Compute, specifically on the Polaris system at ALCF. We'll begin by briefly discussing the popularity and applications of LLMs in various fields. Following this, we will introduce the vLLM tool, and explain how it integrates with Globus Compute to efficiently manage LLM operations on Polaris. Attendees will learn the practical aspects of setting up and remotely triggering LLMs from local machines, focusing on ease of use and efficiency. This talk is ideal for researchers and practitioners looking to leverage the power of LLMs in their work, offering a clear guide to harnessing supercomputing resources for quick and effective LLM inference.

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.
Code reviews are vital for ensuring good code quality. They serve as one of our last lines of defense against bugs and subpar code reaching production.
Yet, they often turn into annoying tasks riddled with frustration, hostility, unclear feedback and lack of standards. How can we improve this crucial process?
In this session we will cover:
- The Art of Effective Code Reviews
- Streamlining the Review Process
- Elevating Reviews with Automated Tools
By the end of this presentation, you'll have the knowledge on how to organize and improve your code review proces
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.

The class diagram is a static model that shows the
classes and the relationships among classes in the
system.
Class diagrams illustrates classes, interfaces, and their
associations. They are used for static object modeling.
A Class diagram gives an overview of a system by
showing its classes and the relationships among them.
Class diagrams display what interacts but not what
happens when they do interact
3. 3
The main building block of a class diagram is the class,
which stores and manages information in the system.
A blueprint that an object made from.
The class contains two major parts:
• Attributes “data members”.
• Operations “method members”.
4. 4
No arrows; info can
flow in both directions
Aggregation – Order class
contains OrderDetail classes.
Could be composition?
9. 9
Class diagrams are great for:
discovering related data and attributes
getting a quick picture of the important entities in a system
seeing whether you have too few/many classes
seeing whether the relationships between objects are too
complex, too many in number, simple enough, etc.
spotting dependencies between one class/object and another
Not so great for:
discovering algorithmic (not data-driven) behavior
finding the flow of steps for objects to solve a given problem
understanding the app's overall control flow (event-driven? web-
based? sequential? etc.)
