Inheritance is a mechanism in object-oriented programming where a new class is created by inheriting properties of an existing class.
Inheritance allows code reusability and saves time and effort in writing new code.
The existing class is called the parent or base class, and the new class is called the child or derived class.
The child class inherits all the properties and methods of the parent class and can also add its ...
Different classes in Java are used to define objects and their behavior.
Classes are the building blocks of Java programs.
They define the properties and methods of objects.
Some commonly used classes in Java are String, Integer, ArrayList, etc.
Classes can be inherited to create new classes with additional features.
Java provides a rich set of predefined classes, and developers can create their own classes.
Inheritance is a mechanism in object-oriented programming where a new class is created by inheriting properties of an existing class.
Inheritance allows for code reuse and promotes a hierarchical organization of code.
The existing class is called the superclass or parent class, and the new class is called the subclass or child class.
The subclass inherits all the properties and methods of the superclass, and can also add ...
Java has four different classes: abstract, final, public and default.
Abstract class cannot be instantiated and is used as a base class for other classes
Final class cannot be inherited and is used to prevent further modification
Public class can be accessed from anywhere in the program
Default class can only be accessed within the same package
Example: public class MyClass {}
Creating public and private classes in Java is useful for encapsulation and access control.
Creating a class as public allows it to be accessed from any other class.
Creating a class as private restricts its access to only within the same class.
Public classes are typically used for classes that need to be accessed by other classes or modules.
Private classes are typically used for helper classes or internal implementation...
A program with 8 loops
Loops can be of different types like for, while, do-while, foreach, etc.
The loops can be nested within each other to create complex logic.
The program can perform various operations within the loops like printing, calculating, etc.

Schema is a blueprint that defines the structure of a database. I used the relational schema in my project.
Schema is a logical representation of the entire database.
It defines the tables, fields, relationships, and constraints.
Relational schema is the most commonly used schema in databases.
It organizes data into tables with rows and columns.
Example: Employee table with columns like ID, Name, Age, Salary.
SQL is a language used to manage relational databases, while ETL is a process used to extract, transform, and load data from various sources into a target database.
SQL is used to manage data within a database, while ETL is used to move data between databases
SQL is used to query and manipulate data, while ETL is used to transform and load data into a target database
SQL is a language, while ETL is a process

Agile methodology is an iterative approach to software development that emphasizes flexibility and customer satisfaction.
Agile focuses on delivering working software in short iterations
It values collaboration between team members and with customers
It emphasizes adapting to change rather than following a rigid plan
Examples of agile methodologies include Scrum, Kanban, and Extreme Programming (XP)
Writing queries involves creating statements to retrieve data from a database.
Identify the data you want to retrieve
Choose the appropriate table(s) to query
Use SQL syntax to construct the query
Test the query to ensure it returns the desired results
Data can be uploaded from source to target using ETL tools or manual data entry.
Extract data from source system
Transform data to match target system requirements
Load data into target system
Use ETL tools like Informatica, Talend, or SSIS
Manual data entry can be done through UI or APIs
Buffer is a temporary storage area in memory used to hold data while it is being processed or transferred.
Buffers are used in various applications such as network communication, file I/O, and image processing.
They help to improve performance by reducing the number of read/write operations to the main memory.
Examples of buffer include input/output buffer, circular buffer, and double buffer.
Buffer overflow is a common vu...
Joins and constraints are used in databases to link tables and enforce rules for data integrity.
Joins are used to combine data from two or more tables based on a related column
Constraints are rules that are applied to columns to ensure data integrity
Types of constraints include primary key, foreign key, unique, and check constraints
Joins can be inner, outer, left, or right depending on the data needed
Examples of joins ...
