Unified Modeling Language UML Views of a Project, Diagramming Notation, Use Cases, Classes, Relationships, Behaviors, States, OCL UML is used by object-oriented designers to relate to each other, how they behave dynamically (both unambiguously specify an OO design, to discuss it with intra- and inter-object) and how they are delivered to other designers and to communicate it to all end-users. Software systems are becoming increasingly stakeholders - developers, end-users and management. complex and at the same time there is persistent pressure to decrease development costs and time scales, We can think of UML as a graphical design language and improve quality. for object oriented software.

Kubernetes How Everything Works Together, etcd, API Server, Scheduler, Controller, Kubelet, CRI, CNI, CSI, Project Once you go beyond running a few containers on a However, after we first review the big picture for single machine, you need to think about how to manage Kubernetes, when we examine each of its components multiple nodes and make them work together at scale in turn, we see they each performs a focused task and that is where Kubernetes comes in. Kubernetes is (storage config, change data, schedule a container, start the leading orchestration system for container clusters. a container). Each component on its own is relatively simple, and so we gradually build up a deeper At first glance Kubernetes is confusing, because it understanding of how Kubernetes actually works. involves multiple components running demanding / varying workloads on different nodes in a network.

There is a need to noticeable by its absence than its presence in an collect as much information as possible from the user – application. This course helps you design it into your via product demonstrations, usability testing, and after products. User interaction design is a branch of software launch, analyzing the helpdesk queries. Just like engineering – and needs to be approached in an advertising, 50% of software features are never used – organized manner. We need to get to know the user, to you will need to find out which, and more importantly discover the user interaction requirements, to build the why – perhaps the unused features are too difficult, app, and then to test that we have done it correctly. This perhaps the user does not know they exist is both similar and different to how we would code up (inaccessible), or perhaps they are simply not needed. an algorithm or implement a database schema.

CSS – Cascading Style Sheets Handling Styling, Selectors, Descriptions, Specificity, Priority, Pseudo-, CSS for ..., SCSS CSS is not a markup language (unlike HTML5) used to be applied to elements. An important consideration is to represent content. CSS is not a programming language maintain the same “look & feel” across multiple pages, (unlike JavaScript/TypeScript), used to dynamically Thus a site-wide “house style” is often defined. Also change content at run time. Rather, CSS is a styling CSS allows the same content to be optimally rendered language used to concisely represent styling on output devices with differing capabilities (size, information for web content. resolution, interactivity) and suitably for people with differing interaction needs. CSS is used to declaratively describe the initial hierarchical set of styles that are to be applied to HTML This course looks at the role of CSS in the world of elements which later may be manipulated by modern web development, provides a detailed tour of TypeScript/JavaScript code. CSS offers considerable CSS features and explores how you can best deploy it flexibility in how styles are specified and how they can for styling your own web solutions.
