REST is an architectural style for building distributed and loosely coupled web services using existing standards like HTTP and JSON. Some best practices for developing RESTful APIs include using nouns for resources, handling asynchronous tasks, combining resources to reduce requests, choosing appropriate representation formats, designing URIs for queries, and implementing security. Error responses should include detailed error information.
The document discusses different levels of REST APIs. Level 3 REST expresses everything as links in the response body. An example is given where a GET request for doctor appointment slots returns an XML response containing the slots with a link to book each slot. Level 3 REST makes APIs browsable by including links to related resources, avoiding the need for separate documentation on how to perform actions.
The document discusses various fallacies and facts related to REST (Representational State Transfer) architectural style. It addresses misconceptions around REST being the same as HTTP, needing standards or tooling, and only applying to human-centric systems. The document emphasizes that REST is defined by the constraints of being stateless, having a uniform interface, separate layered system, and using hypermedia.
This document discusses testing REST web services at three levels: message level, resource level, and application level.
At the message level, tests check for correct HTTP syntax, semantics, and payload syntax and semantics. At the resource level, tests check if resources match link semantics, are available over time, have stable semantics over time, and maintain variants. At the application level, tests check if the service offers expected capabilities and if the user's goal is reachable.
The document provides guidance for both server and client developers, noting what each can rely on and what each must implement to ensure the service under test conforms to the constraints of REST.
The document discusses Representational State Transfer (REST) as an architectural style for building distributed hypermedia systems. It describes key REST principles such as giving every resource an identifier, linking resources together through hyperlinks, using standard HTTP methods like GET, PUT, POST and DELETE, and communicating statelessly. The document also compares REST to other styles like WS-* and contrasts how REST uses URIs and HTTP while WS-* uses SOAP. It provides examples of companies and projects using REST.

Understanding and Using Rest APIs (SocialDevCamp Chicago 2009)Pete Morano
RESTful APIs have become integral to technology and dominate web development. While REST is based on simple principles like using HTTP methods and representing resources, there is still a lack of standardization around documentation and discovery. WADL aims to provide a standard like WSDL for REST that would reduce errors and enable code generation.
API stands for Application Programming Interface. APIs allow communication between applications or services by providing a set of functions and procedures. API testing involves testing APIs and their integration with services to ensure correct functionality, reliability, performance, and security. Postman is a popular tool for API development that allows users to design, build, test, and document APIs through a graphical user interface.
This document provides instructions on setting up the development environment needed to create RESTful web services using the Jersey framework. It describes how to install the Java Development Kit (JDK), Eclipse integrated development environment (IDE), Jersey framework libraries, and Apache Tomcat web server. Detailed steps are provided for configuring the JDK and setting environment variables, downloading and setting up Eclipse, downloading and extracting the appropriate Jersey framework .zip file, and downloading, extracting, and starting Apache Tomcat. Once this environment is configured, the reader will be ready to start building their first RESTful web service application.
This document outlines an agenda to introduce REST and building APIs with ASP.NET Web API. It begins with a quick demo, then discusses what REST is as an architectural style based on HTTP using resources and verbs. It covers HTTP concepts like requests, responses and status codes. Finally, it demonstrates building a REST API with ASP.NET Web API and discusses advantages of REST like using the well-defined HTTP protocol and enabling caching.
This document provides an overview of RESTful APIs and how to build them using Laravel. It defines REST as an architectural style for designing networked applications that use HTTP to perform CRUD operations on resources. The key aspects of RESTful APIs covered include using HTTP verbs like GET, POST, PUT and DELETE; including HTTP headers and status codes; being stateless; and commonly returning JSON or XML responses. The document also discusses authentication methods like OAuth and JSON web tokens that can be used to secure REST APIs. Finally, it outlines the steps that will be covered to build a RESTful API using Laravel, including creating routes, migrations, seeders, models, controllers and request validation.
Roy Fielding introduced the concept of RESTful APIs in 2000. REST has since become a dominant framework for sending requests from clients to servers to interact with and receive data in a format clients can use. A RESTful API uses well-established HTTP methods like GET, POST, PUT, and DELETE to allow standardized communication and efficient use of network resources. REST defines how clients and servers exchange information about resources through standardized requests and responses.
Using REST to aid WS-* proposes building a RESTful SOA registry using Atom and AtomPub protocols to publish, retrieve, and manage SOA metadata and artifacts like WSDLs, schemas, and policies. The registry treats everything as resources accessible through URIs, supports standard CRUD operations, and shows dependencies between services, schemas, and other artifacts. Content handlers can intercept operations to perform validation and manage lifecycles. The approach aims to unify human and machine interfaces for the registry.
REST is an architectural style for designing distributed systems that focuses on resources, representations of those resources, and the links between them. The key aspects of REST include using a stateless client-server architecture, caching, a uniform interface, layered system, and code-on-demand. Well-designed REST APIs use standard HTTP methods like GET, POST, PUT, DELETE on addressable resources and represent them with different media types. Resources are linked together through navigational links to allow the client to traverse the API in a stateless manner.
This document compares REST and SOAP web services and outlines the advantages of REST. It discusses how REST is lighter weight than SOAP, using less bandwidth as it does not require wrapping requests and responses in XML. It also describes how REST is simpler to implement than SOAP, relying on HTTP verbs rather than custom service contracts. REST services allow for easier caching and work better with firewalls. The document promotes REST for its scalability, simplicity and ability to save bandwidth and development time.
This document provides an overview of REST basics and how to implement REST with Spring. It discusses:
1. The differences between SOAP and REST web services standards and how REST uses HTTP methods to perform CRUD operations on nouns instead of defining complex operations.
2. Key aspects of REST including the REST triangle of nouns, verbs, and content types. It also covers common REST frameworks and HTTP methods, headers, and status codes.
3. How Spring supports REST with annotations like @RequestMapping and @ResponseBody to build RESTful web services, and uses the DispatcherServlet to route HTTP requests to controller methods.
4. An example of a basic RESTful web service implemented with

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...IJECEIAES
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

Rainfall intensity duration frequency curve statistical analysis and modeling...bijceesjournal
Using data from 41 years in Patna’ India’ the study’s goal is to analyze the trends of how often it rains on a weekly, seasonal, and annual basis (1981−2020). First, utilizing the intensity-duration-frequency (IDF) curve and the relationship by statistically analyzing rainfall’ the historical rainfall data set for Patna’ India’ during a 41 year period (1981−2020), was evaluated for its quality. Changes in the hydrologic cycle as a result of increased greenhouse gas emissions are expected to induce variations in the intensity, length, and frequency of precipitation events. One strategy to lessen vulnerability is to quantify probable changes and adapt to them. Techniques such as log-normal, normal, and Gumbel are used (EV-I). Distributions were created with durations of 1, 2, 3, 6, and 24 h and return times of 2, 5, 10, 25, and 100 years. There were also mathematical correlations discovered between rainfall and recurrence interval.
Findings: Based on findings, the Gumbel approach produced the highest intensity values, whereas the other approaches produced values that were close to each other. The data indicates that 461.9 mm of rain fell during the monsoon season’s 301st week. However, it was found that the 29th week had the greatest average rainfall, 92.6 mm. With 952.6 mm on average, the monsoon season saw the highest rainfall. Calculations revealed that the yearly rainfall averaged 1171.1 mm. Using Weibull’s method, the study was subsequently expanded to examine rainfall distribution at different recurrence intervals of 2, 5, 10, and 25 years. Rainfall and recurrence interval mathematical correlations were also developed. Further regression analysis revealed that short wave irrigation, wind direction, wind speed, pressure, relative humidity, and temperature all had a substantial influence on rainfall.
Originality and value: The results of the rainfall IDF curves can provide useful information to policymakers in making appropriate decisions in managing and minimizing floods in the study area.

Applications of artificial Intelligence in Mechanical Engineering.pdfAtif Razi
Historically, mechanical engineering has relied heavily on human expertise and empirical methods to solve complex problems. With the introduction of computer-aided design (CAD) and finite element analysis (FEA), the field took its first steps towards digitization. These tools allowed engineers to simulate and analyze mechanical systems with greater accuracy and efficiency. However, the sheer volume of data generated by modern engineering systems and the increasing complexity of these systems have necessitated more advanced analytical tools, paving the way for AI.
AI offers the capability to process vast amounts of data, identify patterns, and make predictions with a level of speed and accuracy unattainable by traditional methods. This has profound implications for mechanical engineering, enabling more efficient design processes, predictive maintenance strategies, and optimized manufacturing operations. AI-driven tools can learn from historical data, adapt to new information, and continuously improve their performance, making them invaluable in tackling the multifaceted challenges of modern mechanical engineering.

•Keep it Simple Stupid
•Keep it small service
•Dont care about the language use the right tool for the job
•Deliver fast
•Find the Entities
•Use a platform that lets you deploy fast
•REST is a common language (should be human readable)
•Good REST API is when people don't need your
documentation to guess the endpoint
