UML Diagrams

Hello everyone and welcome back to another week of my blog. This week I will be talking about UML diagrams. UML stands for Unified Modeling Language and it is used to model business, application structures, programming languages, analysis, design, and implementation of software-based systems. In other words, it is a way to visually represent the design and implementation of complex software. There can be many lines of codes in your software and it can be difficult to keep track of all the class relationships and hierarchies. UML diagrams can make it easier for developers to see the relationships and hierarchies. UML diagrams can work for many different programming languages. It is a standardized modeling language that any language can incorporate into the language of their choosing.

There are two different types of UML diagrams. The two different types are structural and behavioral. Structural UML diagrams show how a system is structured. They show how classes and object components work together and show the relationships between those components. Behavioral UML diagrams on the other hand, show how a system would behave from the objects interacting with each other in it. In this class I am currently taking at Worcester State University, we look at the design and structure of programs through structural UML diagrams. We went through different versions of a “DuckSimulator” and its UML diagrams to see how the program can be improved. When given a difficult concept to add to the DuckSimulator, we were able to come up with a solution through the UML diagram because we could visually see how adding interface classes would affect the DuckSimulator.

The DuckSimulator structural UML diagram we used was a class diagram intended to be written in Java. UML diagrams are very commonly used to represent software that is based on object orientated programming because they can easily show the different classes with their attributes and behaviors as well as the relationships between each class. Class diagrams are split into three vertical sections. The section at the top is the name of the class, the section in the middle are the attributes, and the section at the bottom are the methods. Types of variables and return types of methods are indicated after the name and a colon (id : int). Typically the attributes in the middle section of each class are private variables indicated by a minus sign (-) before the name. Classes can be linked together with many different arrows to show relationships between them. UML diagrams are very powerful at representing a program written with a object orientated language.

REST API

REST APIs provide a flexible, lightweight way to integrate applications, and have emerged as the most common method for connecting components in microservices architectures.

How Does REST API Work: 

Through HTTP, a REST API communicates its request to perform functions like reading, creating, deleting, and updating records within a resource. For example, a REST API receives a request to retrieve a record, a POST to create one, a PUT to update a record, and a DELETE to get rid of one. 

The Six Rules of REST API’s:

There are six REST design principles – also known as architectural constraints, When these constraints are applied to the system architecture, it gains desirable non-functional properties, such as performance, scalability, simplicity, modifiability, visibility, portability, and reliability. A system that complies with some or all of these constraints is loosely referred to as RESTful.

  1. Uniform interface: A uniformed interface within the architecture of the REST API allows the client to interact with the server in one specific language. It also provides for the independent evolution without conjoining its functions to the API.
  1.  Client-Server Separation: The client sends a request to the server, then the server sends a response back to the client. Servers cannot make requests and clients cannot respond — all interactions are initiated by the client. RESTful APIs keep the two conveniently independent. This way, client software can grow their builds without worrying about affecting any other servers, and server contents can be modified without inadvertently affecting clients.
  1. Stateless: As per the REST architecture, a RESTful Web Service should not keep a client state on the server. This restriction is called Statelessness. It is the responsibility of the client to pass its context to the server and then the server can store this context to process the client’s further request.
  1. Layered API System Architecture: As APIs create a communication interface that hides the interactions between them, users don’t get to experience exactly how the services connect. REST APIs send calls and responses through various layers to make the end-user experience smoother. 
  1. Cache-ability: Caching occurs when media is stored on a client’s device when visiting a website. cacheability of resources on either the server or client-side should be possible. This improves scalability, speed, and/or performance.
  1. Code on Demand: its primary duty is to allow for applets and code transmission through the API and use by the application. Simply, it enables the client’s flexibility.
