RDBMS stores data in tables with predefined schema while document DBs store data in flexible, JSON-like documents.

• RDBMS uses SQL for querying while document DBs use their own query language or JSON queries

• RDBMS is better suited for structured data while document DBs are better for unstructured or semi-structured data

• Examples of RDBMS include MySQL, Oracle, and SQL Server while examples of document DBs include MongoDB and Couchbase

A constructor is a special method used to initialize objects in a class.

• Constructors have the same name as the class they belong to.

• They are automatically called when an object is created.

• Constructors can have parameters to initialize object properties.

• They can be overloaded to provide multiple ways of object initialization.

Encoding decoding is the process of converting information from one format to another.

• Encoding is the process of converting information into a specific format that can be easily transmitted or stored.

• Decoding is the process of converting encoded information back into its original format.

A linked list is a linear data structure where each element is a separate object with a pointer to the next element.

• Consists of nodes that contain data and a pointer to the next node

• Can be singly linked or doubly linked

• Used in implementing stacks, queues, and hash tables

Keywords are reserved words in programming languages. Super key is a key that uniquely identifies a record in a table.

• Keywords cannot be used as variable names or identifiers.

• Super key is a combination of one or more keys that uniquely identifies a record.

• Encapsulation is a way of hiding the implementation details of an object.

HTTP/1 is a plain text protocol, HTTP/2 is binary and multiplexed, and HTTP/3 uses QUIC protocol for faster connections.

• HTTP/1 is a plain text protocol with no support for multiplexing, resulting in slower performance.

• HTTP/2 is a binary protocol that allows for multiplexing, header compression, and server push, improving performance.

• HTTP/3 is based on the QUIC protocol, which uses UDP instead of TCP for faster connections and reduced latency.

• HTTP/3 also includes features like...read more

We monitor application performance through various tools and techniques to ensure optimal functionality.

• Utilize monitoring tools such as New Relic, Datadog, or AppDynamics

• Set up alerts for key performance metrics like response time, error rate, and throughput

• Regularly analyze performance data to identify bottlenecks and areas for improvement

Debugging a microservice based application involves identifying and resolving issues in individual services.

• Start by reproducing the issue and gathering relevant logs and error messages

• Use logging and monitoring tools to track the flow of data and identify bottlenecks

• Isolate the problematic microservice and test it independently

• Check for compatibility issues between microservices and their dependencies

• Use debugging tools and techniques like breakpoints, stepping through code,...read more

Overriding is when a subclass provides a different implementation of a method that is already defined in its superclass.

• Overriding is used to achieve runtime polymorphism.

• The method in the subclass must have the same name, return type, and parameters as the method in the superclass.

• The overridden method in the superclass must be marked with the 'virtual' or 'abstract' keyword.

• Example: Inheritance where a subclass overrides a method from its superclass.

Q1: Method overloading is when a class has multiple methods with the same name but different parameters. Q2: A constructor is a special method that is called when an object is created.

• Method overloading allows for more flexibility in a class by allowing multiple methods with the same name but different parameters.

• Constructors are used to initialize the object's state when it is created.

• In Java, constructors have the same name as the class and do not have a return type.

• Example...read more
