process with an example.
 Digital transformation in the education industry helps improve the learning experience
for both students and teachers, as well as other people involved in the process.
 Such changes focus on improving engagement and accessibility through interactive and
customizable learning.
 As a result, online education gets cheaper, more comprehensive, and more inclusive.
Managing admissions
 Uploading your enrollment application to universities or schools online is more
convenient.
 You pick all the institutions of interest and send the respective documents at once.
 This is a time-savvy option that wouldn't just accept your documents but also process
them faster.
Minimizing risks
 Whether a child is sick or the classes were canceled due to harsh weather conditions,
online learning can handle it all.
 Now, to maintain excellent attendance rates and not miss an important lesson, you can
simply click on the "Join" button of the meeting tool or just read through the material
uploaded on the cloud.
Improving learning outcomes
 With interactive lessons and implementing high-tech solutions, you can motivate students
and, as a result, improve their learning skills.
 The more attention they pay to what's going on, the more relevant information they'll be
able to absorb at once.
Evaluating performance
 Students will get faster access to tests and their grades through online systems.
 E-learning systems allow submitting papers, doing instant plagiarism checks, and
tracking attendance.
 All these factors form students' performance levels that you can easily measure via a
digital platform.

1. b. Diagnostic imaging procedures are cutting-edge technology, but at the same time they
are an unpleasant experience for patients – and even more for paediatric patients. Explain
how design thinking helped Doug Dietz, an industrial designer, create a scanner experience
that children loved.
 Diagnostic imaging has revolutionized healthcare, yet GE Healthcare saw a problem in

how pediatric patients reacted to procedures.
 Many children were observed crying during long procedures in cold, dark rooms with
flickering fluorescent lights.
 Considering this, GE Healthcare’s team observed children in various environments,
spoke to experts, and interviewed hospital staff to gain more insight into their
experiences.
 After extensive user research, hospital pilots, and reiteration, GE Healthcare launched the
“Adventure Series.” This redesign initiative focused on making magnetic resonance
imaging (MRI) machines more child-friendly.
 For example, the “Pirate Adventure” transforms MRI machines from dark, black holes to
pirate ships with scenery of beaches, sandcastles, and the ocean.
 By empathizing with children’s pain points, GE Healthcare was able to craft a creative
solution that was not only fun but increased patient satisfaction scores by 90 percent.
 This also yielded unexpected successes, including improved scan quality of pediatric
patients, and ultimately saved customers time and resources.

b. Compare the database communication through JDBC and ORM.
Database communication through JDBC

1. Import the Packages
2. Register the drivers using DriverManager
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver())

3. Establish a connection using the Connection class object

Connection con = DriverManager.getConnection(url,user,password)
4. Create a statement
Statement st = con.createStatement();
5. Execute the query
// user Queries
String sql = "select * from emp";
6. Close the connections
con.close();
Database communication through ORM
Step1: Create a new maven project
Step2: Add required Dependencies:
Spring Web, Spring Data JPA, MySQL Driver
Step3: Create 3 Packages and 3 class with the following names entity, controller and
repository
Step4:
Create User.java class use appropriate annotations
public class User {
private int id;
private String name;
}
Create Usercontroller.java use appropriate annotations
public class Usercontroller {
private UserRepository userRepository;
public List<User> getAllUser()
{
return this.userRepository.findAll();
}}
UserRepository.java interface use appropriate annotations
public interface UserRepository extends JpaRepository<User,Long>{
}

Step5: Write your database connection string with in application.properties file

spring.datasource.url=jdbc:mysql://localhost:3306/emp
spring.datasource.username=root
spring.datasource.password=root
spring.jpa.hibernate.ddl-auto = update
7.a. Illustrate the use of different annotation used in spring boot application.
Annotations
Annotations are used to provide supplemental information about a program.
 Annotations start with ‘@’.
 Annotations help to associate metadata (information) to the program elements i.e. instance
variables, constructors, methods, classes, etc.
 Annotations basically are used to provide additional information, so could be an alternative
to XML and Java marker interfaces.
Spring Annotations List
@Service: Annotate all your service classes with @Service. All your business logic should
be in Service classes.
@Service
public class CompanyServiceImpl implements CompanyService {
...
}
@Repository: Annotate all your DAO classes with @Repository. All your database access
logic should be in DAO classes.
@Repository
public class CompanyDAOImpl implements CompanyDAO {
...
}

@Component: Annotate your other components (for example REST resource classes) with
@Component
@Component
public class ContactResource {
...
}
@Autowired: Let Spring auto-wire other beans into your classes using @Autowired
annotation.
@Service
@Autowired
private CompanyDAO companyDAO;
}
@Transactional: Configure your transactions with @Transactional spring annotation.
@Service
@Autowired
private CompanyDAO companyDAO;
@Transactional
public Company findByName(String name) {
Company company = companyDAO.findByName(name);
return company;
}
}
@Scope: To change default behavior, use @Scope spring annotation.
@Component
@Scope("request")
public class ContactResource {
}

7.b. Converting monolithic application to microservices architecture.
Step 1: Split the code.

Step 2: Split the database.
Step 3: Define a standalone Delivery Service.
Step 4: Use the standalone Delivery Service.
Step 5: Remove the delivery management functionality from the FTGO monolith.
Step 1: Split the code
The first step is to split the code and convert delivery management into a separate, loosely
coupled module within the monolith.
Step 2: Split the database

The second step is split the database and define a separate database schema for the ftgo-
delivery-service module.
Step 3: Define a standalone Delivery Service
The third step of the refactoring process is to define a standalone Delivery Service and deploy
it. The service does not, however, handle production traffic. Instead, it can, for example, be
tested in production.
Step 4: Use the standalone Delivery Service
The fourth step of the refactoring process is to use the standalone Delivery Service.

Step 5: Remove the delivery management functionality from the FTGO monolith
The fifth step of the refactoring process is to remove the now obsolete delivery management
logic from the monolith.
8.a. Create a RESTcontroller class to perform CRUD operations on product and

corresponding request and response DTOs. The product class should contain three data
members product name, product category, price. Use proper SpringBoot annotations.
Note: Create Rest API for Product
8.b. Writing Junit test cases for CRUD operations.
Download JUnit from https://junit.org/junit4/
Goto download & install
Find Plain-old Jar & Download the following
 junit.jar
 hamcrest-core.jar
 Create a folder in any drive by giving relevant name, copy and paste both jar files to the
folder.
 Create a project in eclipse
 Right click on project select build path, click on configure build path
 Select java build path, Click on Libraries and click on class path in libraries, go to Add
External JAR’s, select junit.jar and hamcrest-core.jar files, click on apply and then apply
and close.
 Goto src/test/java folder find default package and Testclass
 Write the below code

// Import required packages & Dependencies

@SpringBootTest
class SpringbootFirstAppApplicationTests {
@Autowired
UserRepository userRepo;
@Test
public void testCreate()
{
User u=new User();
u.setId(3L);
u.setFirstname("Kavya");
u.setLasttname("shree");
userRepo.save(u);
}
@Test
public void testReadAll()
{
List<User> list=userRepo.findAll();
assertThat(list).size().isGreaterThan(0);
}
@Test
public void testUpdate()
{
User u=userRepo.findById(902L).get();
u.setFirstname("Murthy");
userRepo.save(u);
assertNotEquals("Niranjan",userRepo.findById(902L).get().getFirstname());
}
@Test
public void testDelete()
{
userRepo.deleteById(852L);
assertThat(userRepo.existsById(852L)).isFalse();

}
}
9 a. Discuss the Components of Docker container.
Docker container
Docker containers are the live, running instances of Docker images. While Docker images are
read-only files, containers are life, ephemeral, executable content. Users can interact with them,
and administrators can adjust their settings and conditions using Docker commands.
Docker client
Docker client is an application for Mac or Windows that includes Docker Engine, Docker CLI
client, Docker Compose, Kubernetes, and others. It also includes access to Docker Hub.
Docker daemon
Docker daemon is a service that creates and manages Docker images, using the commands from
the client. Essentially Docker daemon serves as the control center of your Docker
implementation. The server on which Docker daemon runs is called the Docker host.
Docker image
Docker images contain executable application source code as well as all the tools, libraries, and
dependencies that the application code needs to run as a container. When you run the Docker
image, it becomes one instance (or multiple instances) of the container.
Docker registry
A Docker registry is a scalable open-source storage and distribution system for Docker images.
The registry enables you to track image versions in repositories, using tagging for identification.
This is accomplished using git, a version control tool.

9. b. Draw the CI/CD build process flow diagram for an online footwear store
application and explain each component

{
const [list, setList] = useState([]);
const [value, setValue] = useState("");
const addToList = () => {
let tempArr = list;
tempArr.push(value);
setList(tempArr);
setValue("");
};
const deleteItem = (index) => {

let temp = list.filter((item, i) => i !== index);
setList(temp);
};
return (
<div className="App">
<h>Add Product to List</h><br></br>
<input type="text" value={value} => setValue(e.target.value)}/>
<button Click to Add </button><br>
<h>Product Catalog</h><br>
<ol>
{
list.map((item, i) => <li => deleteItem(i)}>{item} </li>)
}
</ol>
<h>Click on Product to Delete</h><br></br>
</div>

);
}
export default App;
b) CRUD Operations on document using MangoDB
Creating a Table.
To create collections/tables, createCollection(name, options) method is used.
Syntax: db.createCollection(name, options)
Example: db.createCollection("student")
{ ok: 1 }
show tables
student
insert() Method
To insert data into MongoDB collection, insert() or save() method is used.
Syntax: db.collectonName.insert(document)
Example: db.student.insert({"id":1,"name":"chandru","mark":300})
db.student.insertMany([{"id":1,"name":"chandru","mark":300},
{"id":2,"name":"suman","mark":290}])
View data from Table.

To view/display the documents, find() method is used
Syntax: db. collectonName.find({})
Example: db.student.find({})
Update.
To Update documents, update() method is used
Syntax: db. collectonName.update({})
Example: db.student.update({"name":"chandru"},{$set:{"name":"sekar",id:5}})
Delete only one data.

To Delete documents, deleteOne()/deleteMany() method is used

Syntax: db. collectonName.deleteOne({})
Example: db.student.deleteOne({"name":"sekar"})
Example: db.student.deleteMany({"name":"sekar"})
Model Question paper 2
1. Process involved in enterprise application
Five main steps involved in the process of organizing an enterprise.
1. Determining Activities
 The first step in organizing is to identify and enumerate (to specify one after another) the
activities required to achieve the objectives of the enterprise.
 The activities will depend upon the nature and size of the enterprise.
 For instance, a manufacturing concern will have production, marketing and other.
2. Grouping of Activities
 The various activities are then classified into appropriate departments and divisions on
the basis of functions, products, territories, customers etc.

 Similar and related activities may be grouped together under one department or division.
 Grouping of activities helps to secure specialization. Each department may be further sub
divided into sections and groups.
3. Assigning Duties
 The individual groups of activities are then allotted to different individuals on the basis of
their ability and aptitude.
 The responsibility of every individual should be defined clearly to avoid duplication of
work and overlapping of effort.
 Each person is given a specific job best suited to him and he is made responsible for its
execution.
4. Delegating Authority:
 Every individual is given the authority necessary to perform the assigned task effectively.
 An individual cannot perform his job without the necessary authority or power.
5. Coordinating Activities:
 The activities and efforts of different individuals are then synchronized. Such co-
ordination is necessary to ensure effective performance of specialized functions.
2. How to create project plan
The software plan prevents hurdles that tend to crop up during the project’s
execution. It also ensures optimal utilization of every allotted resource and time.
1. Define your scope:

 A project's scope describes the goals needed to complete the project
successfully.
 Defining your scope, consider project aspects like outcomes, tasks, budget, time
frame and deliverables.
 You can define these by writing them in sentences or creating a bulleted
list within your software project plan document.

2. Define and coordinate your requirements:

 Identify appropriate resources that will help you to meet the objectives.
 Define the other aspects of the project such as equipment, budget for software
development, team, skills, and timeline.
3. Understand your constraints:

 Project may encounter unexpected events that may adversely affect it. Such as
increase in costs, delayed results, technical and business etc.
 Such hurdles include support from the management, appropriate schedule,
appropriate budget, and skilled software developers.
4. Map your business processes:

 Business process mapping is a powerful technique to visually depict process
steps and show how a process should function from start to finish.
5. Estimate your budget:

 The estimates will help you get an idea of the money and time you need.
6. Draw up your staged deliverables:

 Next task is to draw software development milestones to give room for testing
and feedbacks at each phase.
 Milestones ensure the software development team focuses on specific
functionality aspects.
 When planning tasks and features to be done at the various phases, concentrate
more on achieving original targets.
7. Create a team:
 Project management requires one or several teams of professionals with the
right experience and skills.
 If your company lacks these individuals, you may hire from outside or outsource
the recruitment process to a company that will put together the teams for you.
8. Discuss quality and progress:

 Your planning is not yet over until you include the progress checks and quality
testing.
 Testing your stages ensures you’re meeting your milestone goals.
3. How to rendering multiple components in reactJS (List &Keys) with an example.
List: The list is used to display data in an ordered format and is traversed using the map()
function.
import React from 'react';

import ReactDOM from 'react-dom/client';
function NumberList(props) {
const numbers = props.numbers;
const listItems = numbers.map((number) =><li>{number}</li>);
return (
<ul>{listItems}</ul>
);
}
const numbers = [1, 2, 3, 4, 5];
const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(<NumberList numbers={numbers} />);
Keys: Keys are used to identify which items have changed, are added, or are removed.
import ReactDOM from 'react-dom';
function App(props) {
const numbers = props.numbers;
return (
<div>
<ul>
{numbers.map((number) =>
<li key={number.toString()}>{number}</li>
)}
</ul>

</div>
);}
const numbers = ['Indore', 'Mumbai', 'Pune', 'Hyderabad', 'Banglore'];
root.render(<App numbers={numbers} />);
export default App;
4. About type script with example
Control flow statement

TypeScript control statements:
1. If Statement
2. If else statement
3. if else if statement
TypeScript If Statement:
If statement is used to execute a block of statements if specified condition is true.
if(condition){
….
}
TypeScript If Else Statement:

If condition is true then if block will execute otherwise else block will execute.
if(condition){
….
}else{
….
}
TypeScript If Else If Statement:

If condition1 is true then block of statements1 will be executed, else if condition2 is true block of
statements2 is executed and so on. If no condition is true, then else block of statements will be
executed.

if(condition1){
...
}else if(condition2){
...
}else{
...
}
Example
var num:number = 2;
if(num==1){
console.log("TypeScript Statement 1");
}
else if(num==2){
console.log("TypeScript Statement 2");
}
else{
console.log("TypeScript Statement n");
}
TypeScript - for Loops
1. for loop
2. for..of loop
3. for..in loop
for Loop
The for loop is used to execute a block of code a given number of times, which is specified by
a condition.
for (first expression; second expression; third expression ) {
// statements to be executed repeatedly
}
Example:
for (let i = 0; i < 3; i++) {

console.log ("Block statement execution no." + i);

}
for...of Loop
TypeScript includes the for...of loop to iterate and access elements of an array, list, or tuple
collection.
let arr = [10, 20, 30, 40];
for (var val of arr) {
console.log(val);
}
for...in Loop
Another form of the for loop is for...in. This can be used with an array, list, or tuple.
let arr = [10, 20, 30, 40];
for (var index in arr) {
console.log(index);
console.log(arr[index]);
}
TypeScript - while Loop

The while loop is another type of loop that checks for a specified condition before beginning
to execute the block of statements. The loop runs until the condition value is met.
while (condition expression) {
}
Example:
let i: number = 2;
while (i < 4) {
console.log( "Block statement execution no." + i )
i++;
}
do..while loop

The do..while loop is similar to the while loop, except that the condition is given at the end of
the loop. The do..while loop runs the block of code at least once before checking for the
specified condition.
do {
// code block to be executed
}
while (condition expression);
Example:
let i: number = 2;
do {
console.log("Block statement execution no." + i )
i++;
} while ( i < 4)
5. Authentication service
SecurityController.java

@RestController
public class SecurityController
{
@GetMapping("/")
public String welcome() {
return ("<h1>Hello Everyone, Welcome to SpringBoot Security</h1>");
}
@GetMapping("/user")
public String welcomeUser() {
return ("<h1>Hello User, Welcome to SpringBoot Security</h1>");
}
@GetMapping("/admin")
public String welcomeAdmin() {
return ("<h1>Hello Admin, Welcome to SpringBoot Security</h1>");
}

SecurityConfiguration.java
@SuppressWarnings("deprecation")
@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter
{
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.inMemoryAuthentication().withUser("Gagan").password("ABC").roles("USER")
.and().withUser("Deep").password("XYZ").roles("ADMIN");
}
@Bean
public PasswordEncoder getPasswordEncoder() {
return NoOpPasswordEncoder.getInstance();
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers("/admin").hasRole("ADMIN")
.antMatchers("/user").hasAnyRole("USER","ADMIN")
.antMatchers("/").permitAll()
.and().formLogin();
}
}
6. Crud operation on Book using MangoDb
Step 1: Create a Spring Boot project.

Step 2: Add the following dependency
 Spring Web

 MongoDB
 Lombok
 DevTools
Step 3: Create 3 packages and create some classes and interfaces inside these packages
 entity
 repository
 controller
Step 4: Inside the entity package create a Book.java file.
//import required packages & Dependencies
@Data
@NoArgsConstructor
@AllArgsConstructor
@Document(collection = "Book")
public class Book {
@Id
private int id;
private String bookName;
private String authorName;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getBookName() {
return bookName;
}
public void setBookName(String bookName) {
this.bookName = bookName;
}
public String getAuthorName() {
return authorName;

}
public void setAuthorName(String authorName) {
this.authorName = authorName;
}
}
Step 5: Inside the repository package
Create a simple interface and name the interface as BookRepo. This interface is going to
extend the MongoRepository
public interface BookRepo extends MongoRepository<Book, Integer>
{
}
Step 6: Inside the controller package. Inside the package create one class named
as BookController
@RestController
public class BookController {
@Autowired
private BookRepo repo;
@PostMapping("/addBook")
public String saveBook(@RequestBody Book book){
repo.save(book);
return "Added Successfully";
}
@GetMapping("/findAllBooks")
public List<Book> getBooks() {
return repo.findAll();
}
@DeleteMapping("/delete/{id}")
public String deleteBook(@PathVariable int id){
repo.deleteById(id);
return "Deleted Successfully";

}
}
Step 7: Below is the code for the application.properties file
server.port:8989
spring.data.mongodb.host=localhost
spring.data.mongodb.port=27017
spring.data.mongodb.database=jss
7. About pom.xml
 POM stands for Project Object Model. It is fundamental unit of work in Maven. It is an
XML file that resides in the base directory of the project as pom.xml.
 The POM contains information about the project, goals, plugins and various
configuration detail used by Maven to build the project(s).
 Some of the configuration that can be specified in the POM are following
 project dependencies
 plugins
 goals
 build profiles
 project version
Before creating a POM, we should first decide the project group (groupId),
its name (artifactId) and its version as these attributes help in uniquely identifying the project in
repository.
POM Example
<project xmlns = "http://maven.apache.org/POM/4.0.0"
xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation = "http://maven.apache.org/POM/4.0.0
http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.companyname.project-group</groupId>
<artifactId>project</artifactId>

<version>1.0</version>
</project>
Sr.No. Node & Description
1 Project root
This is project root tag. You need to specify the basic schema settings such as apache
schema and w3.org specification.
2 Model version
Model version should be 4.0.0.
3 groupId
This is an Id of project's group. This is generally unique amongst an organization or a
project. For example, a banking group com.company.bank has all bank related projects.
4 artifactId
This is an Id of the project. This is generally name of the project. For example,
consumer-banking. Along with the groupId, the artifactId defines the artifact's location
within the repository.
5 version
This is the version of the project. Along with the groupId, It is used within an artifact's
repository to separate versions from each other. For example −
com.company.bank:consumer-banking:1.0
com.company.bank:consumer-banking:1.1.
8. . React props and state
What are props?

Props is short for properties and they are used to pass data between React components. React’s
data flow between components is uni-directional (from parent to child only).
class ParentComponent extends React.Component {
render() {
return (

<ChildComponent name="First Child" />

);
}
}
const ChildComponent = (props) => {
return <p>{props.name}</p>;
};
root.render(<ParentComponent />);

function Name(props) {
return <h2>My name { props.name }!</h2>;
}
function Display() {
return (
<>
<Name name="Niranjan" />
</>
);
}

root.render(<Display />);
What is state?
React has another special built-in object called state, which allows components to create and
manage their own data. So unlike props, components cannot pass data with state, but they can
create and manage it internally.

class Test extends React.Component {

constructor(props) {
super(props);
this.state = {
id: 1,
name: "test"
};
}
render() {
return (
<div>
<p>{this.state.id}</p>
<p>{this.state.name}</p>
</div>
);
}
}
root.render(<Test />);
9. Create student database with name rollno department percentage in mongoDB and
perform aggregate functions.
db.createCollection("student")
{ ok: 1 }
db.student.insertMany([{"roll no":1,"department":"cs","percentage":25},
{"roll no":2,"department":"mech","percentage":35},
{"roll no":3,"department":"ec","percentage":50}])
Aggregate Function:
db.student.aggregate([{$group : {_id : "roll no", sum : {$sum : "$percentage"}}}])
db.student.aggregate([{$group : {_id : "roll no", max : {$max : "$percentage"}}}])
db.student.aggregate([{$group : {_id : "roll no", min : {$min : "$percentage"}}}])

db.student.aggregate([{$group : {_id : "roll no", last : {$last : "$percentage"}}}])
db.student.aggregate([{$group : {_id : "roll no", first: {$first : "$percentage"}}}])
db.student.aggregate([{$group : {_id : "roll no", average : {$avg : "$percentage"}}}])
10. Compare nosql with rdbms.
NoSQL RDBMS
Non-relational databases, often known as RDBMS, which stands for Relational Database
distributed databases, are another name for Management Systems, is the most common name
NoSQL databases. for SQL databases.
No declarative query language SQL stands for Structured Query Language.
NoSQL databases are horizontally scalable RDBMS databases are vertically scalable
One record stores all the query data. This Relational database models contain data in
simplifies finding matched records, which different tables, because of so many tables, the
speeds up queries. database's query time is slow.
NoSQL Database has no fixed schema. Relational Database has a fixed schema.
NoSQL databases can handle big data or NoSQL databases are used to handle moderate
data in a very high volume . volume of data.
NoSQL has decentralized structure. Relational database has centralized structure.
NoSQL database can manage structured, Relational database manages only structured
unstructured and semi-structured data. data.
NoSQL combines multiple database Traditional RDBMS systems use SQL syntax and
technologies.. queries to get insights from data.
11. Kubernet with deployment model.

Canary deployment

Canary deployment is a technique to reduce the risk of updating software or introducing

new changes in the production environment by slowly rolling out the change to a small subset of
users before making the software functional for everyone.
Pros (Advantages)
 Allows enterprises to test in production with real users and use cases.
 Enables comparison of different service versions side by side.
 Cheaper than blue-green deployments because it does not require two production environments.
 DevOps team can rapidly and safely trigger a rollback to a previous version of an application.
Cons (Disadvantages)
 Scripting a canary release can be complex as manual verification or testing can sometimes
become time-consuming.
 Monitoring and instrumentation for testing in production may involve exhaustive research and
additional skills & knowledge.
Blue/green deployment
Blue/green deployment is a deployment technique to release new code into the
production environment. Blue/green deployments make use of two identical production
environments. One of these is active and the other environment is set to idle. New updates are
pushed to the active environment where it is monitored for bugs while the idle environment
serves as a backup where traffic can be routed in case an error occurs.
Pros
 Simple, fast, easy to understand and implement.
 Rollback is straightforward as teams need to simply flip traffic back to the old environment in
case any issue arises.
 Blue-green deployments are not as risky and vulnerable to losses as compared to other
deployment strategies.
Cons
 Cost is the major drawback to blue-green deployments.
Quality assurance and user acceptance testing may not be enough to identify all of the
regressions.
