Add your answer
Q2. What is exploratory testing, what is regression and retesting, what bug life cycle
Ans. 
Exploratory testing involves simultaneous learning, test design, and execution. Regression testing ensures new code changes do not adversely affect existing functionality. Retesting is done to verify that a fixed bug is resolved.
• Exploratory testing is a hands-on approach where testers explore the application without predefined test cases. They learn the application while testing and design test cases simultaneously.

• Reg...read more

Q1. What is regression
Ans. 
Regression is the process of retesting a software application after changes have been made to ensure that the existing functionalities are not affected.
• Regression testing is done to make sure that new code changes do not adversely impact the existing functionality of the software.

• It involves running test cases that cover the affected areas of the application to verify that everything still works as expected.

• Regression ...read more

Q2. What is retesting, smoke sanity, Exploratory
Ans. 
Retesting, smoke sanity, and exploratory are different types of testing techniques used in quality assurance.
• Retesting is the process of running tests again to verify that a specific bug or issue has been fixed.

• Smoke testing, also known as sanity testing, is a preliminary testing to check if the software build is stable enough for further testing.

• Exploratory testing is a testing approach where testers explore the softw...read more

Q3. What is corelation and Regression
Ans. Corelation refers to the strength and direction among two variables in Linear relation. +1 means +Ve Corelation , -1 means -Ve Corelation , 0 refers to having no corelation . Regression on the other hand refers to the relation of one or more than one independent varible's (x) with a Dependent variable (y) have a linear equation of straight line y=mx+c , where m is aslope and c is an costant .In other word, It determi...read more

Q4. How to reduce dimensional Reduction
Ans. By using PCA( Priciple Component Anlysis ) - Keeping Priciple component of data intact it reduce the dimension of the data from higher dimension to lower space . However K means clustering indirectly reduces dimensional reduction by meansoffeture silection , as same features are having similar charcteristic. .So Segmentation of data on basis of Features reduces indirectly the dimensional reduction

Q1. Diff btw view and indexed view, pipeline design process, where to monitor pipelibe failures and how to fix
Ans. 
View vs indexed view, pipeline design process, monitoring pipeline failures and fixing
• View is a virtual table based on a SELECT query, while indexed view is a view with a clustered index for faster retrieval

• Pipeline design process involves defining data sources, transformations, and destinations

• Monitor pipeline failures using logging tools like Apache NiFi or Airflow

• Fix pipeline failures by identifying the root cause, ...read more
