It is a standardized, general-purpose modeling language that is mainly applied for creating object-oriented, meaningful documentation models for any software system present in the real world. The Unified Modelling Language consists of a set of graphic notation techniques to create visual models. It gives us the means to develop strong models that represent software\/hardware systems&#8217; working. It can be used with all processes during the software development lifecycle and different technologies.<\/p>\n\n\n\n<p>UML normally has two types of diagrams which we are going to discuss below but before that let us discuss UML\u2019s features.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"features-of-uml\"><\/span>Features of UML<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Unified Modeling Language is a generalized modeling language.<\/li>\n\n\n\n<li>It is not the same as other software programming languages such as C, C++, Python.<\/li>\n\n\n\n<li>UML is a pictorial language that can be applied to create powerful modeling elements.<\/li>\n\n\n\n<li>It is similar to object-oriented designs and analysis.<\/li>\n\n\n\n<li>It has extensive applications even outside the software industry.

It describes the interaction in the system.<\/p>\n\n\n\n<p>Following are the different types of behavioral diagrams in UML:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Activity diagram<\/li>\n\n\n\n<li>Use case diagram<\/li>\n\n\n\n<li>State machine diagram<\/li>\n\n\n\n<li>Interaction Diagrams<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"state-machine-diagram\"><\/span>State Machine Diagram:&nbsp;<span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<p>Also known as the State-charts diagram.

It helps us to understand what objects are and How interaction takes place to perform a process. In UML, A conceptual model is required. You need to know the entities and relations between them before modeling the system. Following object-oriented theories are needed to start with UML:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Object<\/strong>: It is a real-world entity. There are many objects possible in a single system. It is a basic building block of Unified Modelling Language.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Class<\/strong>: It is nothing but a vessel where objects and relations are kept.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Abstraction<\/strong>: It is a way of representing an object without exposing the implementation details. It is utilized to reflect the presence of an object.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Inheritance<\/strong>: It is a mechanism of increasing an actual class to produce a different class.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Polymorphism<\/strong>: It represents an object having various forms that are utilized for various purposes.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Encapsulation<\/strong>: It is a way of connecting data and objects data together as one unit.
