Software development methodologies: increasing efficiency in software projects.

In the fast-paced realm of software development, using an effective methodology can make or break a project. The Jain Software team in Raipur knows how important strong methodologies are for delivering excellent software products and solutions. Let’s explore different kinds of software development methodologies, their core principles and how they affect the nature of a specific cycle in this blog post.

1. Waterfall Methodology: Sequential and Structured

Waterfall works in a linear fashion, where development flows through requirements, design, implementation and test phases by carefully dotted steps. Each stage depends on the completion of its predecessor, providing a systematic method particularly suited to projects with clearly defined requirements.

2. Agile Methodology: Iterative and Collaborative

The agile methodology is all about adaptability and teamwork, cutting the project into smaller pieces called sprints. It encourages continuous feedback, so teams can adapt to changes quickly. Because of their focus on customer satisfaction, incremental development and flexibility, agile methodologies such a Scrum and Kanban are especially suited to projects whose requirements change constantly.

3. DevOps: Converging Development and Operations

DevOps is a culture and set of practices that stresses collaboration between development (Dev) and operations (Ops), with the goal being automation throughout all stages of software creation. The approach stresses shorter development cycles, continuous integration and delivery (CI/CD), as well as automated testing to accelerate release cycle times while increasing quality.

4. Lean Software Development: Streamlined Efficiency

Lean methodology strives to eliminate waste, maximize efficiency and add value for the customer. It stresses continuous improvement, avoiding unnecessary processes, and the emphasis of value. Lean is strongly founded upon principles such as eliminating waste, increasing learning and empowering the team.

5. Spiral Model: Iterative Risk Management

The Spiral model combines iterative development with aspects of the Waterfall Model and risk analysis. It consists of repeated cycles, each including planning, risk analysis, engineering and evaluation. This methodology is suitable for complex projects, where risk management and frequent evaluations are important.

Choosing the Right Methodology: Considerations and Factors

Selecting the appropriate methodology for a project involves considering several factors:

• Project Type and Scope: From this analysis of project complexity, requirements and uncertainties we can determine the best-fit methodology.
• Team Size and Expertise: Such assessment of team capabilities and expertise can help with the choice of methodology that suits its strengths.
• Client Collaboration: Some methodologies stress client involvement and feedback. Others follow a more rigid format.
• Flexibility and Adaptability: Understanding the need for adaptability to changes throughout a project’s lifetime is essential.

The Jain Software Approach: Tailoring Methodologies for Success

We know at Jain Software in Raipur that there’s no single methodology to fit all projects perfectly. Therefore we use an approach which combines the advantages of different methodologies according to particular project needs. Efficiency, quality and client satisfaction Our team carefully assesses project needs along with customer expectations against the capabilities of our people to choose a strategy that is both effective and well received.

Conclusion

Thus, software development methodologies provide guiding frameworks to direct the course of a software project. At Jain Software in Raipur, we are aware that the choice of methodology is important to the success of a project. Looking to build on the strengths of each methodology and customize our approach, we hope to provide high-quality software that doesn’t just meet expectations but helps fuel success.

A detailed blog post offers understanding about software development methodology with insights on their importance and how Jain Software in Raipur adopts different approaches for projects to be successful.

Software development in the Dynamic Realm of Programming Languages

Programming languages are the bedrock of software development, enabling programmers to create all sorts of novel applications that support our digital lives. At Jain Software in Raipur, we appreciate the importance of programming language to building stable software applications. In this post we’ll explore the rich ecosystem of programming languages and their importance for modern software construction.

The Foundation: Understanding Programming Languages

Programming languages are indispensable means of communication, a way for humans to pass instructions on how to perform their tasks. These help to translate human-readable code into machine executable instructions, telling computers what and how they should do.

1. Python: The Versatile Powerhouse

Blessed with its simplicity and readability, Python is a versatile programming language used in many different areas. Its simple syntax and complete libraries make it well suited to rapid application development, data analysis, AI operations and machine learning. As a highly flexible language with plentiful community support, Python is popularly used by both novices and veterans alike.

2. JavaScript: Driving Interactivity on the Web

As the basis for interactive web development, JavaScript provides developers with a way to create rich and responsive user experiences. JavaScript is a client-side scripting language, allowing seamless interaction on websites. It’s essential for front-end development work. JavaScript has come of age in the era of frameworks like React, Angular and Vue.js that now enable robust single-page applications (SPAs) and enhance user experience.

3. Java: Powering Enterprise Solutions

Scalable and platform independent, Java also continues to be an indispensable cornerstone in enterprise-level software development. The JVM and the “write once, run anywhere” philosophy keep it compatible between different platforms. With its strong typing system, performance (especially unparalleled in the Java world) and rich libraries for applications such as banking, e-commerce and Android app development.

4. Swift: Transforming iOS Development

Apple’s brainchild, Swift revolutionized iOS app development with its power, security and modern syntax. Swift, as successor to Objective-C, simplifies the development process and shows increased performance and readability. Robust and user-friendly features have made it popular among developers, encouraging them to build just such complete and rich applications for iOS.

5. C#: Empowering Windows Ecosystem

The versatile C# developed by Microsoft shines as the leading language in delivering applications within the Windows ecosystem. It allows rapid development of Windows applications, games and enterprise solutions through integration with the .NET framework. C# is highly suitable for development of Windows-centered applications, with its strong typing system and ease of scalability. It also provides wide support for object oriented programming.

Choosing the Right Language: Factors to Consider

Selecting the most suitable programming language for a project involves careful consideration of various factors:

Project Requirements: The appropriate language can be selected by evaluating the project’s needs, scalability and expected functionalities.

Performance: Some languages are particularly good for performance-critical applications, and some put a premium on ease of development.

Community Support: As development proceeds, a rich community and thorough documentation provide assistance.

Ecosystem and Libraries: Efficiency requires that we evaluate whether existing frameworks, tools or libraries are consistent with the language.

Adapting to Change: The Evolution of Programming Languages

The tech ecosystem is constantly changing, new languages are being born and existing ones transformed. Jain Software in Raipur is now kept informed of these developments, learning and adapting to modern paradigms and languages. With new languages, horizons expand and rapid-fire solutions take shape.

Conclusion

The languages of programming offer software developers the building blocks for revolutionary applications. Recognizing the importance of programming languages in our trade at Jain Software, Raipur we use them to implement powerful and original software solutions designed around what our clients want. Understanding the pros and cons of each language, we select only appropriate tools that deliver top-notch quality software driving success for customers.

In line with Jain Software’s vision for technological superiority and innovation in Raipur, this all-inclusive post looks at explaining the importance of programming languages to software development users.

Bootstrap: A complete package for WEB

Bootstrap

BOOTSTRAP is  a complete package for web who wants to become a web designer. Bootstrap is the most popular HTML, CSS, and JS framework for developing responsive, mobile first projects on the web sites.

HTML:

Defines data and structure of a page using elements under html.

CSS:

Defines how the data and elements actually looks and behave when interact with them.

JS: 

This is actually programming language of a web know as java script.

History of Bootstrap:

Bootstrap is a front-end development framework that enables developers & designers to quickly build fully responsive websites. The framework contains global CSS settings with built-in components and extensible classes in the form of typography, navigation, buttons,form,tabbing and much more.

Bootstrap was originally developed by former Twitter employees Mark Otto and Jacob Thornton, as an internal development tool to improve consistency and efficiency of web page.

It was in August 2011, released as a open source project on github and become a most popular repository platform.

Very easy Installation: 

Installation is very easy, just download the source file of bootstrap and upload on server and just put the references or  links of available files into your header. The installation process work is covered with that work.

example-

<!-- Latest compiled and minified CSS -->
<link rel="stylesheet" href="link of your file" > (this is for .css file)

<!-- Latest compiled and minified JavaScript --> <script src="link of .js file" ></script>

How to start:

You should remember this format to start ..

<!DOCTYPE html>
<html>
<head>
<title>Title Name</title>
</head>
<body>

<h1>This is a Heading</h1>
<p>This is a paragraph.</p>

</body>
</html>

Basic HTML elements-

• Title- <title></title>- this is use for give title of the page.
• Header- <h1>…<h6>- this element is use for give the heading of content.
• Paragraph-<p></p>- This element is use for give a paragraph.
• Simple block element-<div></div>

How to use CSS:

• Internal / Embedded Styles. Internal Styles are placed inside the head section of a particular web page via the style tag.

<style>

.clr{

color:red;

background-color:yellow;

}

#code{

font-size:12px;

}

</style>

• Inline Styles. Inline Styles cannot be resused at all, period.

<div style="color:red,margin:12px 0 0 0"></div>

• External Style Sheet. For the most part, we will want to place the majority of our Style Rules on an External Style Sheet.

<link href=”link of your file” rel=”stylesheet” type=”text/css”/>

How to use Javascript (JS File):

• Internal: Internal script are placed inside the page wherever you want via the sscript tag.

<script type="text/javascript">

$(document).ready(function(){

Your code here.....

});

</script>

• External- For the external link first you have to create a .js file in and set link in html page.

<script src="js file address" type="text/javascript" ></script>

Features:

• css resetting for cross browser compatibility.
• grid scaffolding for design.
• Multi screen support.(Fully Responsive)

Javascript plugin:

• Dialogs
• Tabs
• Alerts
• Carousel
• tooltips and many more..

Customization:

• You can customize the css according to your requirements.
• You can use LESS to compile your a bootstrap css version on your own.
• You can just download the customize version from http:/bootswatch.com

Adding Twitter Bootstrap:

You should use CDN links also..like

For CSS-

<link href=”https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css” rel=”stylesheet”/>

For Javascript File- 

<script type=”text/javascript” src=”https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js”></script>

Node.js and its universe

It’s absolutely no doubt that JavaScript is ruling the web world.JavaScript’s rising popularity has brought with it a lot of changes, and the face of web development today is dramatically different. The things that we can do on the web nowadays with JavaScript running on the server, as well as in the browser, were hard to imagine.

As official website states: “Node.js® is a JavaScript runtime built on Chrome’s V8 JavaScript engine. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient.” In simple words we can say that this technology runs JavaScript on server side.

Node.js was introduced late in 2009 by Ryan Dahl at a JavaScript conference with an idea to enrich the server side with the power of JavaScript. Back in past most of the real time web application are created by using client server architecture. In such architecture we have to use two different languages for client side and server side scripting for example we use php as a server side language  and JavaScript for scripting in client side.

But node.js removes this conflict, Now we can write real time as well as complex web applications in just one language using node.js. This will definitely removes the overhead of bridging both languages and debugging them individually.

Node.JS owes its incredible speed and performance to a technique called the event loop and The fact that it runs on top of V8, the JavaScript interpreter and virtual machine that Google Created to make their Chrome web browser run impossibly fast

Installing Node

Node.js is very easy to install. If you’re using Windows or Mac, installers are available on the download page.

Installing on windows

On Windows, go to http://nodejs.org and download the MSI installer. Every release of node has a corresponding MSI installer that you need to download and execute. The filename follows the format nodev?.?.?.msi. Upon executing it, simply follow the instructions in the setup wizard shown in fig

To ensure that the installation worked, open the shell or command prompt by running cmd.exe and typing

node –version.

The version name of the package you just installed should display.

Installed Node. What Next?

Once installed you’ll have access to a new command called “node”. Now Open the node command and run this command to check if it’s working

node –version

You can see it simply output your node version on screen

You can use the node command in two different ways. The first is with no arguments. This will open an interactive shell (REPL: read-eval-print-loop) where you can execute raw JavaScript code. The other way to run Node is by providing it a JavaScript file to execute. This is almost always how you’ll be using it.

To open REPL simply type node on command prompt the cursor will now come in next line with a “ > ” sign here you can write and evaluate JavaScript code if you’re a beginner with javascript you can test your expressions here. Type following to test environment

console.log(‘Hello World’);

Further you can try this

object.keys(global)

Secondly you can write your code on a js file and execute it with node command

Open Your favorite text editor and write these lines and save it first.js.

var http = require(‘http’);

var serv = http.createServer(function (req, res) {

res.writeHead(200, { ’Content-Type’: ’text/html’ });

res.end(’<marquee>Node Running Everywhere!</marquee>’);});

serv.listen(3000);

Run the file:

open shell or node command prompt and type

node first.js

In the above code snippet, you’re harnessing the power of Node to script a fully compliant HTTP server that serves a basic HTML document.

Node.js use asynchronous callbacks. Basically when you tell it to do something and when it’s done it will call your function (callback). This is because Node is single-threaded. While you’re waiting on the callback to fire, Node can go off and do other things instead of blocking until the request is finished.

This is especially important for web servers. It’s pretty common in modern web applications to access a databases. While you’re waiting for the database to return results Node can process more requests. This allows you to handle thousands of concurrent connections with very little overhead, compared to creating a separate thread for each connection.

Further we will discuss more about npm –  the package manager for node.js and other powerful features of it.

TRENDS IN DATA MINING

What is Data Mining:

•  Data mining is the process of extraction of interesting patterns or knowledge from huge amount of data.
• Using information contained within data warehouse, data mining can often provide answers to questions. Like….
  • Which products should be promoted to a particular customer?
  • Which securities will be most profitable to buy or sell during the next trading session?

Application of data mining:

Here is the list of areas where data mining is widely used −

• Healthcare
• Finance

• Data mining for business continues to expand as e-commerce and marketing becomes mainstream elements of the retail industry.

Scalable Data Mining Methods:

• As data is expanding at a massive rate, there is a need to develop new data mining methods which are scalable and can handle different types and large volume of data.
• The data mining methods should be more interactive and user friendly.
• One important direction towards improving the repair efficiency of the timing process while increasing user interaction is constraint-based mining.

Combination of data mining with database, data warehouse, and web database systems:

• Database, data warehouse, and WWW are loaded with huge amounts of data and are major information processing systems.
• The desired architecture for data mining system is the tight coupling with database and data warehouse systems.
• Transaction management query processing, online analytical processing and online analytical mining should be integrated into one unified framework.

Standardization of data mining language: 

Today few data mining languages are commercially available in the market like Microsoft’s SQL server 2005, IBM Intelligent Miner and many more…..

Standard data mining language or other standardization efforts will provide the orderly development of data mining solutions, improved interpret-ability among multiple data mining systems and functions.

Visual Data Mining:

• The result of the mined data can be shown in the visual form So it will further enhance the worth of the mined data.
• Visual data mining is an effective way to discover knowledge from huge amounts of data.
• The systematic study and development of visual data mining techniques will promote the use for data mining analysis.

Web Mining:

• The WWW is globally distributed collection of news, advertisements, consumer records, financial, education, government, e-commerce and many other services.
•  The WWW also contains huge and dynamic collection hyper linked information, providing a large source for data mining.
• Based on the above facts, the web also poses great challenges for efficient resource and knowledge discovery.

Need of Data Mining:

•  The massive growth of data from terabytes to perabytes is due to the wide availability of data in automated form from various sources as WWW, Business, Society etc….
• We are drowning in data but deficient of knowledge Data is useless, if it cannot deliver knowledge.
• That is why data mining is gaining wide acceptance in today’s world.

An introduction to AngularJS

What is Angular JS?

• AngularJS (commonly known as “Angular” or “Angular.js”) is an open-source web application framework mainly maintained by Google and by a community of individual.
• AngularJS is a JavaScript framework. It can be added to an HTML page with a <script> tag.
• AngularJS extends HTML attributes with Directives, and binds data to HTML with Expressions.
• AngularJS is a JavaScript framework. It is a library written in JavaScript.

AngularJS Extends HTML:

AngularJS extends HTML with ng-directives.

• The ng-app directive defines an AngularJS application.
• The ng-model directive binds the value of HTML controls (input, select, textarea) to application data.
• The ng-bind directive binds application data to the HTML view.

Simple Angular JS Example:

<!DOCTYPE html>
 <html>
 <script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js">
</script>
 <body>

<div ng-app="">
 <p>Name: <input type="text" ng-model="name"></p>
 <p ng-bind="name"></p>
 </div>

</body>
 </html>

Why Angular JS:

Here are some reasons why you should be using Angular today.

• MVC Done,
• A declarative User interface,
• Write less code,
• Behavior with directives,
• Flexibility with filters.

Alternatives:

Other frameworks deal with HTML’s shortcomings by either abstracting away HTML, CSS, and/or JavaScript or by providing an imperative way for manipulating the DOM.

Advantages of Angular JS:

On the other hand, Angular JS is a framework. It provides a lot of features that you don’t get with using a library like jQuery

1. Templates
2. Two way data binding
3. Form Validations
4. Deep Linking for dynamic pages
5. MVW pattern (similar to MVC)
6. Communication with server
7. Reusable components and localization to name a few

What is Holography?

History of Holography:

• Invented in 1948 by Dennis Gabor for use in electron microscopy, before the invention of the laser.
• Leith and Upatnieks (1962) applied laser light to holography.

Conventional vs. Holographic photography:

Conventional: 

• ¨2-d version of a 3-d scene
• ¨Photograph lacks depth perception
• ¨Film sensitive only to radiant energy
• ¨Phase relation (i.e. interference) are lost

Hologram: 

• ¨Freezes the intricate wave front of light that carries all the visual information of the scene
• ¨To view a hologram, the wave front is reconstructed
• ¨View what we would have seen if present at the original scene through the window defined by the hologram
• ¨Provides depth perception

Hologram Properties:

• If you look at these holograms from different angles, you see objects from different perspectives, just like you would if you were looking at a real object.
• They usually just look like sparkly pictures or smears of color.
• If you cut one in half, each half contains whole views of the entire holographic image.

Hologram Construction:

• Laser : Red lasers, usually helium-neon (HeNe) lasers, are common in holography
• Beam splitter: This is a device that uses mirrors and prisms to split one beam of light into two beams.
• Mirrors: These direct the beams of light to the correct locations.
• Holographic film: Holographic film can record light at a very high resolution, which is necessary for creating a hologram. It’s a layer of light-sensitive compounds on a transparent surface, like photographic film.

Hologram Working:

Holography Reconstruction:

What is Laser:

Lasers produce monochromatic light — it has one wavelength and one color. Because of the need for coherent interference between the reference and object beams

Hologram:Some Applications:

1. Authentication.
2. Virtual Display.
