Credit management and pricing are related as creditworthiness affects pricing decisions.

• Creditworthiness of a customer affects the interest rate they are offered for loans or credit cards.

• Higher credit scores may result in lower interest rates and fees.

• Credit risk is also a factor in determining pricing for financial products.

• For example, a lender may charge higher interest rates to customers with lower credit scores to offset the risk of default.

• Credit management practices c...read more

Serverless architecture is a cloud computing model where the cloud provider manages the infrastructure and automatically scales resources.

• Serverless architecture eliminates the need for managing servers and infrastructure

• It allows developers to focus on writing code and deploying applications

• Resources are provisioned and scaled automatically based on demand

• Examples of serverless services include AWS Lambda, Azure Functions, and Google Cloud Functions

Interfaces define contracts for behavior while abstract classes provide partial implementation.

• Interfaces cannot have implementation while abstract classes can have partial implementation

• A class can implement multiple interfaces but can only inherit from one abstract class

• Interfaces are used for loose coupling while abstract classes are used for code reuse

• Example of interface: Comparable interface in Java

• Example of abstract class: Animal class with abstract method 'makeSound'

Auto wiring in Spring Boot is a feature that allows Spring to automatically inject dependencies into a bean.

• Auto wiring eliminates the need for manual configuration of dependencies in Spring beans

• It can be achieved by using @Autowired annotation

• There are different types of auto wiring modes like 'byType', 'byName', 'constructor', and 'autodetect'

Abstract class can have both abstract and non-abstract methods, while interface can only have abstract methods.

• Abstract class can have constructors, fields, and methods, while interface cannot have any implementation.

• A class can implement multiple interfaces but can only inherit from one abstract class.

• Abstract classes are used to define a common base class for related classes, while interfaces are used to define a contract for classes to implement.

• Example: Abstract class 'Sh...read more

Stored procedures in MySQL are precompiled SQL statements that can be saved and reused.

• Stored procedures are used to improve performance and reduce network traffic.

• They can be used to encapsulate business logic and complex queries.

• They can also be used to enforce security and access control.

• Stored procedures are created using the CREATE PROCEDURE statement.

• They can be called using the CALL statement.

Async improves performance by allowing non-blocking execution of tasks.

• Async programming allows multiple tasks to run concurrently, improving overall system throughput.

• By avoiding blocking operations, such as waiting for I/O or network requests, other tasks can continue execution.

• Async programming can utilize resources more efficiently by reducing idle time.

• It enables better responsiveness in user interfaces by not blocking the main thread.

• Examples of async programming in act...read more

Pricing procedure determination is the process of defining how prices are calculated for products or services.

• Pricing procedure determination involves defining condition types, which are used to calculate prices based on various factors such as quantity, discounts, taxes, etc.

• The pricing procedure is determined based on the sales area, customer, and material master data.

• Examples of condition types include discounts, surcharges, freight charges, taxes, etc.

• The pricing procedur...read more

• The city offers a good work-life balance with affordable cost of living.

• Chennai has a rich cultural heritage and diverse cuisine to explore in free time.

Item Category Determination is the process of assigning a category to a product based on its attributes.

• Consider the product's features such as size, weight, material, and intended use

• Use a classification system such as UNSPSC or NAICS

• Automate the process using machine learning algorithms

• Ensure accuracy by regularly reviewing and updating categories

Developed a project using the concept of operating systems to optimize resource allocation and improve performance.

• Implemented process scheduling algorithms like Round Robin and Priority Scheduling.

• Utilized memory management techniques such as paging and segmentation.

• Used synchronization mechanisms like semaphores and mutexes to prevent race conditions.

Yes, I have experience with both MERN and SERN stacks.

• Proficient in MongoDB, Express.js, React, and Node.js

• Experience building full stack applications using MERN/SERN stack

List, Tuple, Dict, and Array are data structures in Python with different characteristics and use cases.

• List: Mutable, ordered collection of items. Example: [1, 2, 3]

• Tuple: Immutable, ordered collection of items. Example: (1, 2, 3)

• Dict: Unordered collection of key-value pairs. Example: {'key1': 'value1', 'key2': 'value2'}

• Array: Homogeneous collection of items with fixed size. Example: [1, 2, 3]
