Roll-up and scan components are both used in data processing, but they have different functions and purposes.

• Roll-up is a data aggregation technique that summarizes data at a higher level of granularity.

• Scan component, on the other hand, is used to read and process data sequentially.

• Roll-up is commonly used in data warehousing to generate summary reports or perform calculations on aggregated data.

• Scan component is often used in data processing pipelines to iterate through lar...read more

Data structures in C++ are used to organize and store data efficiently.

• C++ provides various built-in data structures like arrays, linked lists, stacks, queues, trees, and graphs.

• These data structures can be used to store and manipulate data in an efficient manner.

• C++ also allows for the creation of user-defined data structures using classes and structures.

• The choice of data structure depends on the type of data and the operations that need to be performed on it.

SDLC stands for Software Development Life Cycle, a process used by software engineers to design, develop, and test software applications.

• SDLC is a structured process that consists of several phases including planning, analysis, design, implementation, testing, and maintenance.

• Each phase of SDLC has its own set of activities and deliverables to ensure the successful completion of the software project.

• Examples of SDLC models include Waterfall, Agile, and DevOps, each with its o...read more

Union combines and removes duplicates, Union All combines without removing duplicates.

• Union merges the result sets of two or more SELECT statements and removes duplicates

• Union All merges the result sets of two or more SELECT statements without removing duplicates

• Union is slower than Union All as it involves removing duplicates

• Example: SELECT column1 FROM table1 UNION SELECT column1 FROM table2;

• Example: SELECT column1 FROM table1 UNION ALL SELECT column1 FROM table2;

List is mutable, tuple is immutable in Python.

• List can be modified after creation, tuple cannot.

• List uses square brackets [], tuple uses parentheses ().

• List is used for collections of items that may change, tuple for fixed collections.

• Example: list_example = [1, 2, 3], tuple_example = (4, 5, 6)

Binary search is a search algorithm that finds the position of a target value within a sorted array.

• It works by repeatedly dividing in half the portion of the array that could contain the target value.

• It has a time complexity of O(log n).

• It can be implemented recursively or iteratively.

• Example: Searching for the number 7 in the sorted array [1, 3, 5, 7, 9] would return index 3.

SDLC in testing refers to the Software Development Life Cycle followed specifically for testing purposes.

• SDLC in testing involves planning, designing, executing, and evaluating the testing activities within the overall software development process.

• It includes phases such as requirement analysis, test planning, test design, test execution, and test closure.

• SDLC in testing ensures that the software meets the specified requirements and is of high quality before release.

• Examples ...read more

Automation testing is the use of software tools to control the execution of tests and compare actual outcomes with expected outcomes.

• Automation testing helps in reducing manual effort and time required for testing.

• It ensures faster feedback on the quality of the software being tested.

Polymorphism is the ability of a single function or method to operate on different types of data.

• Polymorphism allows objects of different classes to be treated as objects of a common superclass.

• It enables a single interface to represent multiple underlying forms.

• Examples include method overloading and method overriding in object-oriented programming.
