Big Data refers to large and complex datasets that cannot be easily managed or processed using traditional data processing techniques.

• Big Data is characterized by the 3Vs: Volume, Velocity, and Variety.

• Volume refers to the vast amount of data generated and collected from various sources.

• Velocity refers to the speed at which data is generated and needs to be processed in real-time.

• Variety refers to the different types a...read more

Data can be analyzed by using various techniques such as data mining, machine learning, and statistical analysis.

• Use data mining techniques to discover patterns and relationships in the data

• Apply machine learning algorithms to make predictions and classifications

• Utilize statistical analysis to identify trends and draw conclusions

• Use visualization tools to present the data in a meaningful way

• Employ parallel processing a...read more

C is a procedural programming language while C++ is an extension of C with added features of object-oriented programming.

• C is a procedural language, while C++ supports both procedural and object-oriented programming.

• C++ has additional features like classes, objects, inheritance, and polymorphism.

• C++ supports exception handling and templates, which are not available in C.

• C++ allows function overloading and operator over...read more

Object-oriented programming is a programming paradigm that uses objects to represent and manipulate data. Procedural programming is a programming paradigm that uses procedures or functions to structure the program.

• Object-oriented programming focuses on objects and their interactions.

• Procedural programming focuses on procedures or functions.

• In object-oriented programming, data and behavior are encapsulated within object...read more

OOP is a programming paradigm that uses objects to represent and manipulate data and behavior.

• Encapsulation: bundling data and methods together in a class

• Inheritance: creating new classes from existing ones

• Polymorphism: using a single interface to represent different types

• Abstraction: simplifying complex systems by breaking them into smaller, manageable parts

Early binding and late binding are two different approaches to linking functions or methods to their respective code.

• Early binding is done at compile-time, where the function call is resolved before the program is executed.

• Late binding is done at runtime, where the function call is resolved during the program's execution.

• Early binding provides better performance as the function call is already resolved.

• Late binding all...read more

Functions are blocks of code that perform a specific task and can be reused throughout a program.

• Functions are used to break down a program into smaller, manageable parts.

• They improve code reusability and modularity.

• Functions can take input parameters and return output values.

• Examples of functions include calculating the square root of a number or sorting an array.

Functions are used in a program to modularize code, improve code reusability, enhance readability, and simplify debugging.

• Functions help break down complex tasks into smaller, manageable parts.

• They promote code reusability by allowing the same code to be used multiple times.

• Functions enhance code readability by organizing code into logical blocks.

• They simplify debugging as errors can be isolated and fixed within a spec...read more

An abstract class in Java is a class that cannot be instantiated and is used as a blueprint for other classes.

• An abstract class can have both abstract and non-abstract methods.

• It can have abstract methods without any implementation.

• It can also have non-abstract methods with implementation.

• Abstract classes are meant to be extended by other classes.

• To use an abstract class, it must be extended and its abstract methods mu

Abstract methods are methods without implementation. They are used to enforce implementation by subclasses.

• Abstract methods are declared with the 'abstract' keyword and end with a semicolon instead of a method body.

• They are used in abstract classes to enforce implementation by subclasses.

• Subclasses must provide an implementation for all abstract methods or be declared as abstract themselves.

• Abstract methods are useful ...read more

RDBMS is a type of DBMS that stores data in a structured manner using tables and enforces relationships between them.

• DBMS is a software system that manages databases, while RDBMS is a specific type of DBMS.

• RDBMS uses a tabular structure to store data, with each table consisting of rows and columns.

• RDBMS enforces the ACID properties (Atomicity, Consistency, Isolation, Durability) to ensure data integrity.

• RDBMS supports ...read more

Primary key is a unique identifier for a record in a database table. Candidate key is a potential primary key. Composite key is a combination of two or more columns to uniquely identify a record.

• Primary key uniquely identifies a record in a table

• Candidate key is a potential primary key that can be chosen as the primary key

• Composite key is a combination of two or more columns to uniquely identify a record

• Example: In a t...read more

A foreign key is a column or a set of columns in a database table that refers to the primary key of another table.

• Foreign keys establish relationships between tables in a relational database.

• They ensure referential integrity and maintain data consistency.

• Foreign keys can be used to enforce constraints and enable cascading updates or deletes.

• They allow data from multiple tables to be linked together based on common valu...read more
