Linear regression is used for continuous variables, while logistic regression is used for binary outcomes.
Linear regression is used to predict a continuous outcome based on one or more input variables.
Logistic regression is used to predict the probability of a binary outcome based on one or more input variables.
Linear regression assumes a linear relationship between the independent and dependent variables, while logist...
Normalization in DBMS is the process of organizing data in a database to reduce redundancy and improve data integrity.
Normalization involves breaking down data into smaller, more manageable tables and establishing relationships between them.
It helps in reducing data redundancy, minimizing data anomalies, and improving data consistency.
There are different normal forms such as 1NF, 2NF, 3NF, BCNF, and 4NF, each with spec...
Array difference is finding the elements that are present in one array but not in another.
Use set operations like difference to find elements in one array but not in another.
Example: arr1 = ['a', 'b', 'c'], arr2 = ['b', 'c', 'd'], arr_diff = set(arr1) - set(arr2) = ['a']
A gridiron is a metal framework used for grilling food over an open flame, enhancing flavor through direct heat.
Commonly used for grilling meats like steaks and burgers.
Can be made from stainless steel or cast iron for durability.
Allows fat to drip away from food, reducing grease.
Often used in outdoor cooking, such as barbecues and campfires.
I appeared for an interview in Sep 2024, where I was asked the following questions.
JavaScript (JS) is a versatile, high-level programming language primarily used for web development to create interactive content.
Client-side scripting: JS runs in the browser, enabling dynamic content updates without reloading the page. Example: Form validation.
Event-driven programming: JS responds to user actions like clicks and key presses. Example: Dropdown menus that expand on click.
Asynchronous programming: JS can...

Utilize appr...
A stored procedure is a set of SQL statements that can be saved and reused in a database management system.
Stored procedures are used to perform a specific task or set of tasks in a database.
They can accept input parameters and return output parameters.
Stored procedures can improve performance by reducing the amount of data sent between the database and the application.
They can also enhance security by controlling acce...
Ranking functions in SQL are used to assign a rank to each row based on a specific criteria.
Ranking functions include RANK(), DENSE_RANK(), and ROW_NUMBER()
RANK() assigns a unique rank to each distinct row
DENSE_RANK() assigns a unique rank to each distinct row without gaps
ROW_NUMBER() assigns a unique sequential integer to each row
It was a group presentation
DCA analysis in reservoir refers to Decline Curve Analysis, a method used to estimate future production rates of oil and gas wells.
DCA is a common technique in reservoir engineering to forecast production decline over time.
It involves fitting a decline curve to historical production data to predict future performance.
Different decline curve models like exponential, hyperbolic, and harmonic are used depending on the res...
