Views can be updated to include new columns or filter criteria.
Example: CREATE OR REPLACE VIEW my_view AS SELECT * FROM my_table WHERE column = 'value';
Types of triggers include DML triggers, DDL triggers, and logon triggers.
DML triggers are fired in response to data manipulation language (DML) events like INSERT, UPDATE, DELETE.
DDL triggers are fired in response to data definition language (DDL) events like CREATE, ALTER, DROP.
Logon triggers are fired in response to a LOGON event.
INSTEAD OF triggers are used to perform an action instead of the triggering action.
Views can improve query performance by simplifying complex queries and reducing the need for redundant code.
Views can store complex queries and calculations, allowing for easier access and reuse of data.
Views can help optimize performance by pre-aggregating data or joining tables in advance.
Views can reduce the need for writing repetitive code by encapsulating common logic.
However, views can also introduce overhead if ...
Using sp_ prefix for stored procedures can cause performance issues and conflicts with system procedures.
sp_ prefix is reserved for system stored procedures in SQL Server, so using it for user-defined procedures can lead to conflicts.
Using sp_ prefix can cause unnecessary overhead as SQL Server first searches in the master database for system procedures before looking in the user database.
Avoiding sp_ prefix can improv...
I manage daily tasks by prioritizing sprint tasks and addressing user issues promptly.
Prioritize sprint tasks based on deadlines and importance
Communicate with team members to ensure tasks are on track
Address user issues promptly to maintain system functionality
Use project management tools like Jira to track progress
I applied via Referral and was interviewed in Oct 2024. There was 1 interview round.
Find the length of the longest subsequence of contiguous integers in an array.
Sort the array
Iterate through the array and check for consecutive integers
Keep track of the longest subsequence found
Use flatMap and map to extract list of pincodes from Employee objects
Use flatMap to flatten the list of Addresses in each Employee object
Use map to iterate over the flattened list and extract the pincodes
Example: employeeList.stream().flatMap(emp -> emp.getAddresses().stream()).map(address -> address.getPincode()).collect(Collectors.toList())
Database pooling is a technique used to manage a pool of database connections for efficient resource utilization. HikariCP is a popular database connection pooling library in Java.
HikariCP is a high-performance database connection pooling library for Java applications.
It is known for its low latency and high throughput.
Configurations for HikariCP include settings such as maximum pool size, connection timeout, and idle ...

I want to switch to explore new technologies and challenges in a different industry.
Interested in learning new skills and technologies
Seeking new challenges and opportunities for growth
Want to explore different industry perspectives
I applied via Naukri.com and was interviewed in Apr 2024. There was 1 interview round.
Java collections are data structures that store and manipulate groups of objects.
Types of collections include List, Set, Map, Queue, etc.
Internal workings involve data structures like arrays, linked lists, hash tables, etc.
Collections framework provides interfaces and classes for working with collections.
Count occurrences of a specific string in an array of strings.
Iterate through the array and use a HashMap to store the count of each string.
Use the string as key and increment the count each time it is encountered.
Return the count of the specific string at the end.
Using stream to filter a list of strings
Use the filter method to apply a predicate to each element in the stream
Convert the stream back to a list using the collect method
A pn junction diode is a semiconductor device that allows current to flow in one direction only.
Consists of p-type and n-type semiconductor materials
When forward biased, allows current to flow easily
When reverse biased, blocks current flow

A closure is a function that has access to its own scope, the scope in which it was defined, and the global scope.
A closure is created when a function is defined inside another function.
The inner function has access to the variables and parameters of the outer function, even after the outer function has finished executing.
Closures are useful for creating private variables and functions in JavaScript.
They can also be us...
Encapsulation is the process of hiding internal details and providing a public interface for accessing and manipulating data.
Encapsulation bundles data and methods together into a single unit.
It helps in achieving data abstraction and data hiding.
By encapsulating data, we can control access to it and prevent unauthorized modifications.
Encapsulation promotes code reusability and maintainability.
Example: A class in objec...
Inheritance is a concept in object-oriented programming where a class inherits properties and behaviors from another class.
Inheritance allows for code reuse and promotes the concept of hierarchy.
The class that is being inherited from is called the superclass or base class.
The class that inherits from the superclass is called the subclass or derived class.
The subclass can access the public and protected members of the s...
Abstraction is the process of simplifying complex systems by focusing on essential details.
Abstraction involves hiding unnecessary details and exposing only relevant information.
It allows developers to create models or representations that capture the essential aspects of a system.
Abstraction helps in managing complexity, improving code reusability, and enhancing maintainability.
For example, in object-oriented programm...
Polymorphism is the ability of an object to take on many forms. It allows objects of different classes to be treated as the same type.
Polymorphism is a fundamental concept in object-oriented programming.
It enables code reusability and flexibility.
Polymorphism can be achieved through method overriding and method overloading.
Example: A parent class Animal can have multiple child classes like Dog, Cat, and Bird. They can ...
