Java Training in Delhi

JAVA- Platform Independent Programming Language

What do you mean by Java?

Java is widely used programming language that helps in developing the programs that runs on Windows, Linux or Mac. Java is easy to use and is simply an object-oriented programming model. It is used for creating applications as well as small application module. Java is popular due to many reasons like programs that are created in Java have portability in a network. Source code systemizes in byte code which runs anywhere in a network. Java Virtual Machine translates the byte code into a code that runs on computer hardware and other programming languages such as C++ or COBOL assembles the code into a binary file. Another reason why Java is popular is because it is object-oriented. In Java data is secure as it does not use any pointers like C++ and the data that is converted to byte code by Java is not intelligible to humans and preventing the changes from an unknown source Java runs the programs inside a sandbox. For execution purpose Java applet has designed other characteristics to make it run fast.

Unlike other programming language Java is easy to learn and especially for those who are from C background. Java and Java Script share similarities in syntax but both are different constructs. Java mainly helps in writing the programs easily for developers and uses various components that are found in Java EE. Developer has an access for building, deploying, debugging and monitoring the applications on Google cloud. Java is mostly preferred by android users due to its security reasons and object oriented.

Java has some criticism too for example Java syntax is too verbose. It is more memory consuming and significantly slower than the other programming languages. And it is slightly costly due to the memory and processing requirements. And in Java the programmer does not have any right for collecting the garbage. Besides that it is easy to learn and it has a feature of stack allocation systems. It helps in storing and restoring the data easily. And it has the capability of performing several tasks simultaneously within a program. So, it is obvious from above information that Java is widely used because of its benefits and this high usage demands training.

So, if you are looking for Java training in NOIDA then visit Sky Infotech it offers the best and in-depth training of Java. The faculty of the institute is well educated and has good experience in their respective fields. Besides having a good faculty Sky Infotech is well-equipped also.

IOT Training in Noida

WHAT IS IOT?

IOT stands for Internet of things. Anything that can connect to the internet is what IOT is and by the means of anything is any object that is implanted with any software or electronics. And these things are not just mobile phones, computer or PCs it can be a microwave, refrigerator or washing machines and etc. IOT is basically an inter-connected world or a platform where every device has its own smart capabilities and can easily connect with each other and has the ability to exchange the data with each other. In more simple words, IOT is a technology that makes everyone’s life easier as using IOT helps in learning the experiences from each other different devices connect with each other and also helps in collaborating. So, the aim of IOT is to reduce the involvement of human beings in a machine cycle. The machines are always connected to each other and are pre-instructed and can also modify their functions according to our needs. Now always remember that web and internet are two different things. Web is basically a way of sharing or accessing the information that is available on internet whereas internet is a huge network that connects the different devices. Internet has a huge role in sharing the information from one device to another.

APPLICATIONS OF IOT

1) IOT in everyday life

Selenium can be use for understanding the concepts and afterwards can use other tools. Selenium is flexible and extensible hence, easy to use. Moreover, it supports multiple languages as well as multiple browsers.

COMPONENTS OF SELENIUM

There are four major components of selenium. First component is,

1) Selenium IDE

Selenium IDE is one of the component of Selenium which is an add-on for Firefox and is a record & playback plugin. Selenium IDE can be used for quick prototype testing.

2) Selenium RC (Remote Control)

Selenium RC is also called Selenium 1 and it is use for executing the testing scripts and it can be in any language as Selenium supports multi-languages and the execution of scripts is done using JavaScript. But for a time period, Selenium 1 is not actively supported.

3) WebDriver

WebDriver is the third component of Selenium and it is actively used for frameworks. WebDriver is an API (Application Program Interface) which is used to directly interact with the browser. It is the successor to Selenium RC. Both, WebDriver & Selenium RC are emerged to form Selenium 2.

4) Selenium Grid

Selenium grid is the last component of Selenium. Selenium grid is a tool that helps in running the test cases on multiple platforms simultaneously and helps in minimizing the execution time too.

IMPORTANCE OF SELENIUM

For web application testing, moving from manual to automation selenium is one of the best open source library tool.

PHP Training in Noida

WHAT IS HYPERTEXT PROCESSOR?

(PHP)

PHP is a back-end programming language or a server-side programming language. With the help of PHP, website can become more dynamic and is easy to use. But for learning PHP one must know how to use HTML CSS. Java Script is not mandatory for PHP, if someone has learned PHP then it will be easy to understand Java Script. To save the information in website one must have a database. Server-side programming language helps in connecting the website to a database. Word press & Facebook both are written in PHP. With the help of PHP, stuff can be insert into a database and vice-versa. PHP helps in making ‘COOKIES’ & ‘SESSIONS’ and lot of other stuffs can also be done with the help of PHP. It is not compulsory to always do stuffs related to database, many more stuffs can be done too that are not connected to database. The concepts behind Java Script and PHP are very different from HTML CSS because HTML CSS has different type of coding. PHP code will not be visible from the client’s side.

In the beginning PHP will be hard to learn. People will learn some stuff that will not make any sense but with the time it will start making sense.

Downloading a server in a computer is a quick and an easy task to do. It doesn’t harm computer in any way. And for downloading a server ‘XAMPP’ software is must there are other programs too for downloading a server but this software is available for both ‘Windows Linux’ and ‘Mac’.

Chatbot Training in Noida

WHAT IS CHATBOT?

Chatbot is a computer program where interaction is done between human beings and computers. And the interaction takes place via written messages or voice. Chatbot helps in answering the questions and provide answers in a natural language as if a person is interacting with another person. Now a question might be occurring in your mind, that How CHATBOTs know all the answers? Well, a chatbot provides an answer via ‘MACHINE LEARNING’ or with the help of ‘PRE-DEFINED SCRIPTS’.

Sometimes what happens is, even CHATBOT doesn’t know the answer of the given question. So during this kind of situation, chatbot either diverts the conversation or pass the question to the human operator. And in both the cases CHATBOT learns from that interaction for future purpose. After a certain point of time and multiple interactions chatbot gains appropriate scope. The complexity of chatbot is displayed by the sophistication of its software and the data that it can access. And if the chatbot is not at all connected to the relevant data then it has no use.

Here are some examples of CHATBOT.

-AMAZON’S ‘ALEXA’

-I PHONE’S ‘SIRI’

-MICROSOFT’S ‘CORTANA’

Whenever, we are asking something from them like, What is today’s temperature? OR Is it going to rain today?- then we’re interacting with the CHATBOT. Chatbot is a way to increase one’s business. So many travel companies are looking for ways in which they can use ‘CHATBOT’ to improve the customer’s experience in shopping, booking services and to have a good customer service. So chatbot is a great help for interaction through instant messages.

Wide usage of chatbot is primarily reason for high demand for chatbot training. SkyInfotech provides in-depth Chatbot training in Noida.

Different models for creating JAVA based web applications

A British scientist at CERN (the European organization for nuclear research) invented the World Wide Web in 1989. He created the web to support information sharing between scientists around the world. On April 30th 1993, CERN put the world wide web software in the public domain. CERN made the next release available with an open license and the rest is history. And now, we can build our own applications.

The basic web architecture

The basic web architecture is a kind of client/server network architecture. With a client/server network some computers on the network will make requests for things. These are the clients. Other computers will act to serve up a response to the client. These computers are known as servers. For example, when you type or click in your browser for your favorite website, a request is sent to a server. The server will then try to provide the item or items that are requested.

In the beginning of the web, most requests were for static pages. This means we were simply requesting the contents of stored files that didn’t change often to be sent back and displayed in our browser. A dynamic web application is one where the output provided to the client may be different at any moment, based on the current status of data. Data that can determine what is viewed by the client may be data provided by the user in a form. Data is stored as cookies in the client’s computer and is accessed by the application. Current data like date, time, the browser used or the operating system used or the client behavior on the view that trigger related updates.

In the dynamic web model, a client will make a request which is sent over the internet to the web server. The web server will determine which application to run and will request that the application do stuff. At sometime while the application is processing, it may access storage to get any relevant stuff it needs to complete the processing. Data can be returned from storage and then the application will create its output. The output will be passed back to the web server which will in turn, use the output to create a response which will be sent back to the client. The browser will receive the response and render the results.

Use of JAVA to make dynamic web applications

We can use JAVA to make dynamic web applications. With JAVA we have a few different architectures that we can choose from. The most basic is known as the JAVA model 1 architecture. The model 1 architecture is sometimes adequate for web applications with limited processing requirements. With model 1 JSPs are used to handle all processing as well as presentation for the application.

JSPs are capable of connecting and directing the use of JAVA classes which can be applied to take care of the business logic of the application. Storage can be hard drives with flat files or a database. With the JAVA model 1 architecture, a request is made by the client. The web server will then request that the JSP do some things. The JSP will start the processing and work with the model which may try to get stuff from storage. Data can be passed back to the application. The JSP will use the data to create the output and then pass the output back to the web server. The web server will create the response and then pass that back to the client over the internet, which will render the results. When we need more processing power we use the JAVA model 2 architecture.

JAVA is being widely used for web development and demand for JAVA training is quite high. Sky Infotech offers in-depth JAVA training in Noida and it leads the pack of institutes in reckoning for best JAVA training institute in Noida tag. As this institute is located nearby to Noida sector-59 metro station, it is easily accessible from every corner of Delhi/NCR.

Einstein Discovery- Add intelligence to any Salesforce app

Today consumers are using applications which have intelligence imbedded to it. Whenever they open their mobile phone (android or iOS) or desktop and go to their favorite website, they encounter imbedded intelligence that plays vital role in providing better experience to them, although most customers don’t really know about this embedded intelligence. Prime example of this is Netflix recommendations. Salesforce team pondered, why not bring in similar capabilities inside salesforce applications, to make them smarter. This philosophy was behind launch of Einstein discovery.

Introducing Einstein Discovery

Basically Einstein discovery is an application that allows business users to find trends by analyzing data. It enables business users to crunch multiple types of combinations possible to uncover answers using machine learning technique. So, using this application as a business user or an analyst, you will be able to uncover the story of your data. You will be able to uncover the correlation between the outcome that you have defined and all the variables that may have impact on this outcome. It is also going to show you the story that explains the outcome. It also creates a model behind the scene.

Einstein discovery demo- Make DreamHouse App smarter

DreamHouse app is a demonstration application that you can see on developer.salesforce.com. Think about redfin or zillow, communities that allow you to post your house with characteristics, so that people choose it from among other properties for sale. In DreamHouse application, one can see properties and brokers and stuff like that. Wouldn’t it be great if you could predict most important KPIs when you have to sell a house? If you want to predict how much you will get for your house (price), Einstein discovery can help. If one goes to properties and selects a house, details about the house appears. In addition Einstein discovery widget also shows up. Inside this widget, predicted selling price based on the characteristics of the house can be seen. Not only that, reason for the prediction is also visible. Einstein discovery even suggests how you can improve your outcome and what can you do to make the price better. Now question arises, how to create such models inside Salesforce. You definitely don’t need to rely on data scientists. You just need to go to Einstein discovery to create the model and the story behind it.

If you want to learn about Einstein discovery then enroll for Salesforce training course of Sky Infotech. Sky Infotech offers in-depth Salesforce training in Noida and has been in running for best Salesforce training institute in Noida tag for a while now.

Cross browser testing using Selenium

What is Cross Browser Testing?

Cross browser testing refers to testing of a application in multiple browsers like internet explorer, chrome, firefox etc., so that we can test our applications effectively. Cross browser testing is a very important concept in automation because here the actual automation comes into the picture. Say, you have twenty test cases to execute manually. For you it is not a big deal because you can execute it within one or two days. However, if the same test cases have to be executed in five different browsers, number of test cases goes up to hundred automatically and time taken will be considerably more. If you automate these twenty test cases and run them, obviously it will not take more than one or two hour. This is where actual cross browser testing comes into the picture.

Why cross browser testing is needed?

Before talking about need for cross browser testing, let me tell you what is cross browser compatibility. Cross browser compatibility is the ability of a website or a web application to function across different browsers and different operating systems. Which means your web applications or websites should work absolutely fine across all the different browsers like chrome, internet explorer, firefox or safari and even across all operating systems like windows, Mac, iOS etc.

Now let us talk about need of cross browser testing. Basically a simple website comprises of three major technologies, HTML5, CSS3 and JavaScript. But there are hundreds of technologies that are there in the backend that are Python, Ruby, Node.js etc. and all of these backend technologies can be used. But in the frontend, in the rendering only HTML5, CSS3 and JavaScript are used. However, each browser uses a completely different rendering engine to compute these three technologies. For example, Google chrome uses blink, firefox uses keko and internet explorer uses edge, html and chakra. Because of this same website will be rendered completely differently by all these different browsers. That’s exactly why you need cross browser testing. For better experience you need to do cross browser testing, so that the customer gets the same UI of application when using different browsers.

How to perform cross browser testing in automated way using Selenium WebDriver?

· If you are using selenium webdriver then you can automate test cases using internet explorer, firefox, chrome, safari, edge and many more.

· In order to execute test cases for different browsers in same machine at the same time, you can integrate TestNG framework for Selenium WebDriver.

· You can write test cases to check for cross browser compatibility.

Selenium is being widely used and demand for selenium training is huge. Sky Infotech provides in-depth Selenium training in Noida and it has been in reckoning for that coveted tag of best Selenium training institute in Noida for quite some time now.
