Most of us have in our IT careers worked on REST Api's and SOAP requests without deep diving into what they exactly represent. This presentation was created from a testers perspective to understand the concept of API & WSDL and how they come to represent REST and SOAP requests
APIs are one of the main elements of cloud services. All major cloud service providers expose REST APIs to allow you to programmatically access their services and capabilities. SOAP and REST are the two most common ways of exposing APIs, whether to external, partner, cloud, or internal developers.
The concept of API management is to publish these web APIs for consumption, and includes capabilities such as monitoring, security, and documentation.
This presentation introduces basic concepts of APIs, API management, cloud REST services, and a brief walkthrough of WSO2 API Manager and the Oracle API Gateway to see how you can centrally publish, expose, and secure APIs, essentially virtualizing your backend services.
Automation API testing becoming a crucial part of most of the project. This whitepaper provides an insight into how API automation with REST Assured is certainly the way forward in API testing.

Join the Confluent Product Marketing team as we provide an overview of Confluent Platform 5.5, which makes Apache Kafka and event streaming more broadly accessible to developers with enhancements to data compatibility, multi-language development, and ksqlDB.
Building an event-driven architecture with Apache Kafka allows you to transition from traditional silos and monolithic applications to modern microservices and event streaming applications. With these benefits has come an increased demand for Kafka developers from a wide range of industries. The Dice Tech Salary Report recently ranked Kafka as the highest-paid technological skill of 2019, a year removed from ranking it second.
With Confluent Platform 5.5, we are making it even simpler for developers to connect to Kafka and start building event streaming applications, regardless of their preferred programming languages or the underlying data formats used in their applications.
This session will cover the key features of this latest release, including:
-Support for Protobuf and JSON schemas in Confluent Schema Registry and throughout our entire platform
-Exactly once semantics for non-Java clients
-Admin functions in REST Proxy (preview)
-ksqlDB 0.7 and ksqlDB Flow View in Confluent Control Center
Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

Automobile Management System Project Report.pdfKamal Acharya
The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.

Editor's Notes
REST is Representational State Transfer. It is an architectural style that provides connectivity between two systems irrespective of the framework used.
It uses the HTTP Protocol.
A Web Service that uses REST is called REST or RESTful Web Services.
Applications and their features exchange data and information through defined APIs. These APIs can be the seeded ones provided by Oracle EBS or deploy custom APIs to EBS to expose EBS objects, concurrent programs etc.
We can perform Create, Read, Update and Delete operations on the resources through REST Services. For these operations, we use various HTTP Methods
provide a common data access layer that can be accessed from any platform
can be called from your Web Browser
These are different ways in which a custom mobile app can be developed and deployed for EBS.
ISG – gateway for deploying REST Services.
Oracle seeded APIs and custom APIs can be developed and deployed
Oracle E-Business Suite Integrated SOA Gateway (ISG) provides a SOA based infrastructure to provide, consume and monitor web services from E-Business Suite
It is a complete repository of all the integrations for EBS.
Use the Integration Repository user interface to perform design-time activities such as generate and deploy Oracle E-Business Suite Web services
This slide talks about the standard configurations required for deploying REST Services in ISG.
steps required to search and deploy REST Services in ISG.
Mobile apps can be developed based on any mobile development framework. REST APIs once deployed in ISG can be used across mobile apps. But we need to apply REST API patches for custom mobile development in EBS.
Security grants are very important to limit the access based on the users. For every interface/ REST API deployed, security grant must be provided.
Click on the check box of the required REST API and click on Deploy button. The status will now be changed to Deployed.
