UML 2.4 has 14 types of diagrams: 7 structure diagrams and 7 behavior diagrams. See the overall hierarchy and description of each type in the provided link.
UML diagram for inventary management library system
Which UML diagram is drawn first depends on the software design process, system analysed or designed, etc. If you start by collecting requirements, your first diagrams will be use case diagrams. If you start by existing system analysis, it could be class diagrams of domain model. If you create some services, you might start with component diagrams. If your system is in specific domain, you might start with profile diagrams...
Class diagram is UML diagram describing static structure of a system on the (lowest) level of classifiers (classes, interfaces, etc.). It shows system's classifiers, their attributes, and the relationships between classifiers.The following nodes and edges are typically drawn in a UML Class diagram:ClassInterfaceInterface RealizationRequired InterfaceAssociationGeneralizationDependency
Component and deployment diagrams are different UML diagrams. They both show components - but at different levels.Component diagram shows components and dependencies between them, interfaces they provide (implement) or require, classes that realize component. It has no deployment nodes - as deployment diagram does.Deployment diagram shows deployment architecture of system - how components and artifacts are deployed to nodes - execution environments and devices.Though we can show dependencies between components both on component diagrams as well as on deployment diagrams, but we are not showing implementation of components on deployment diagrams as we do on component diagrams.Note, that in UML 1.x deployment diagrams components were directly deployed to nodes. In UML 2.x artifacts are deployed to nodes, and artifacts could manifest components. So, on deployment diagrams components are now deployed to nodes indirectly through artifacts, and generally speaking in UML 2 deployment diagram could show only nodes and artifacts, and no components.
Use case UML diagrams depict functionality (use cases) offered by a system (subject) from a point of view of external user (actor), what designed or existing system can or is supposed to do for external users of the system.See examples of use case diagrams in the related link.
See examples of different types of UML diagrams, select which diagrams you need, find a tool to draw UML diagrams.
UML is visual language - various rectangles, ovals, lines, arrows, etc. each having special meaning and used to draw different diagrams.Microsof Visio is software product that you can purchase to draw UML diagrams on your computer. There are many other UML tools that you can get even for free to draw UML diagrams. Or you can draw UML diagrams with a pencil on a piece of paper.

UML 2.4 has 14 different types of diagrams, so you will need to draw not one diagram but several of those. See provided link for online shopping UML examples which provides examples of several common types of UML diagrams.

UML 2.4 has 14 types of diagrams: 7 structure diagrams and 7 behavior diagrams.Behavior diagrams show the dynamic behavior of the objects in a system, which can be described as a series of changes to the system over time.So any of the behavior diagrams could be called run time diagram (except probably use case diagrams).
A few examples of open source tools for UML diagrams are ArgoUML, ATL, and Eclipse UML2 Tools. All three work on any platform, being implemented in Java.
You can find several examples of UML diagrams - use cases, components, activities, communication, deployment - for e-shopping in the provided link.
