Software development life cycle (SDLC) is a process used to design, develop, test, and maintain software.

• SDLC is a systematic approach to software development.

• It consists of several phases such as requirements gathering, design, coding, testing, deployment, and maintenance.

• Each phase has specific activities and deliverables.

• SDLC models include Waterfall, Agile, and DevOps.

• Example: In the requirements gathering phase, t...read more

A defect is an issue or flaw in a software application that causes it to behave incorrectly or produce incorrect results.

• Defects are also known as bugs or software errors.

• Defects can occur in any phase of the software development lifecycle.

• Defects can be categorized based on their severity and priority.

• Examples of defects include crashes, incorrect calculations, and user interface issues.

Different types of joins in SQL include inner join, left join, right join, and full outer join.

• Inner join returns only the matching rows from both tables

• Left join returns all rows from the left table and the matching rows from the right table

• Right join returns all rows from the right table and the matching rows from the left table

• Full outer join returns all rows from both tables, including unmatched rows

The syntax of inner join is used to combine rows from two or more tables based on a related column between them.

• Use the SELECT statement to specify the columns you want to retrieve from the tables.

• Use the INNER JOIN keyword followed by the table names and the ON keyword to specify the join condition.

• The join condition is typically a comparison between the related columns in the tables.

• Example: SELECT column1, column2 F...read more

Defect life cycle is the process of identifying, reporting, fixing, and verifying software defects.

• Defect is identified during testing or by users

• Defect is reported with detailed information

• Defect is assigned to a developer for fixing

• Developer fixes the defect and marks it as resolved

• Defect is retested to verify if it is fixed

• If the defect is not fixed, it is reopened

• Once verified, the defect is closed

There are various types of testing in software development, including unit testing, integration testing, system testing, and acceptance testing.

• Unit testing: Testing individual components or units of code to ensure they function correctly.

• Integration testing: Testing the interaction between different components or modules to ensure they work together as expected.

• System testing: Testing the entire system or application ...read more

We used a combination of black box and white box testing techniques in our project.

• Black box testing: Testing the functionality of the software without knowledge of its internal structure.

• White box testing: Testing the internal structure and implementation of the software.

• Example: For black box testing, we created test cases based on the software requirements and validated the expected outputs. For white box testing, w...read more

Software testing life cycle is a process that defines the various stages involved in testing a software application.

• Software testing life cycle consists of different phases such as requirement analysis, test planning, test design, test execution, and test closure.

• During the requirement analysis phase, the testing team reviews the requirements and identifies testable features.

• In the test planning phase, the test strateg...read more
