- Q1. What are the ACID properties in database management systems?
- Ans.
ACID properties are a set of properties that guarantee reliability and consistency in database transactions.
ACID stands for Atomicity, Consistency, Isolation, and Durability.
Atomicity ensures that a transaction is treated as a single unit of work, either all of its operations are executed or none.
Consistency ensures that a transaction brings the database from one valid state to another.
Isolation ensures that concurrent...
- Q2. What is a transaction in the context of a Database Management System (DBMS)?
- Ans.
A transaction is a logical unit of work that consists of multiple database operations that must be executed as a single, indivisible unit.
A transaction ensures data consistency and integrity.
It follows the ACID properties: Atomicity, Consistency, Isolation, and Durability.
Transactions are used to maintain data integrity in databases.
Examples of transactions include transferring funds between bank accounts or updating i
- Q3. What is the difference between SQL and NoSQL databases?
- Ans.
SQL databases are relational databases that use structured query language, while NoSQL databases are non-relational databases that use various data models.
SQL databases are based on a fixed schema, while NoSQL databases are schema-less.
SQL databases are better suited for complex queries and structured data, while NoSQL databases are better for unstructured and semi-structured data.
SQL databases ensure ACID (Atomicity, ...
- Q4. What is a semaphore?
- Ans.
A semaphore is a synchronization object that controls access to a shared resource through the use of a counter.
Semaphores are used to manage concurrent access to shared resources in multi-threaded or multi-process environments.
They can be used to limit the number of threads or processes that can access a resource simultaneously.
Semaphores can have two types: counting semaphores and binary semaphores.
Counting semaphores...
- Q5. How can you achieve multitasking in Java?
- Ans.
Multitasking in Java can be achieved using threads.
Create multiple threads to execute tasks concurrently.
Use the Thread class or the Runnable interface to define the tasks.
Use synchronization mechanisms like locks or semaphores to coordinate access to shared resources.
Java provides built-in support for multitasking with the Thread class and the Executor framework.
Example: creating two threads to perform different tasks
- Q6. Can you design a schema for restaurant applications, similar to Zomato?
- Ans.

Create tables for restaurants, users, reviews, and orders
Include columns for restaurant details like name, address, cuisine type
Include columns for user details like name, email, and password
Link reviews to restaurants and users
Link orders to restaurants and users
Consider additional tables for menu items, categories, and ratings

- Q1. Minimum weight to reach bottom right corner in matrix starting from top left. you can move only down and right
- Ans.
The minimum weight to reach the bottom right corner in a matrix starting from the top left by moving only down and right.
Use dynamic programming to calculate the minimum weight at each cell by considering the weights of the cells above and to the left.
At each cell, the minimum weight to reach that cell is the minimum of the weight of the cell itself plus the minimum weight of the cells above and to the left.
Example: Fo...

- Q3. What is transaction?
- Ans.
A transaction is a unit of work that is performed on a database.
A transaction is a sequence of database operations that are treated as a single unit of work.
It ensures that all the operations are completed successfully or none of them are performed.
Transactions are used to maintain data consistency and integrity in a database.
Examples of transactions include transferring money between bank accounts or updating inventor
- Q4. Difference between sql and nosql dbs

SQL is a relational database while NoSQL is a non-relational database.
SQL databases use structured query language while NoSQL databases use unstructured query language.
SQL databases are vertically scalable while NoSQL databases are horizontally scalable.
SQL databases are good for complex queries while NoSQL databases are good for large amounts of unstructured data.
Examples of SQL databases include MySQL, Oracle, and Po...
- Q5. How to achieve multitasking in java
- Ans.
Multitasking in Java can be achieved through multithreading.
Create a new thread using the Thread class or Runnable interface
Use the start() method to start the thread
Synchronize shared resources to avoid race conditions
Use wait() and notify() methods for inter-thread communication
Example: creating a thread to perform a long-running task while the main thread continues executing other tasks
- Q6. What is semaphores?
- Ans.
Semaphores are a synchronization tool used to control access to a shared resource.
Semaphores can be used to prevent race conditions in multi-threaded programs.
They can be used to limit the number of concurrent accesses to a resource.
Semaphores can be binary (0 or 1) or counting (0 to n).
Examples of semaphore functions include wait(), signal(), and init().

- Q1. Hashing and collision in hashing
- Ans.
Hashing is a process of converting data into a fixed-size output. Collision occurs when two different inputs produce the same output.
Hashing is used for indexing and retrieving data quickly
Hash functions should be deterministic and produce the same output for the same input
Collisions can be resolved using techniques like chaining or open addressing
Examples of hashing algorithms include MD5, SHA-1, and SHA-256
