Waterfall is a linear sequential approach to software development, while Agile is an iterative and flexible approach.

• Waterfall follows a linear sequence of phases (requirements, design, implementation, testing, maintenance), while Agile breaks the project into smaller iterations.

• Waterfall requires all requirements to be defined upfront, while Agile allows for changing requirements throughout the project.

• Waterfall has a fixed scope and timeline, while Agile is more flexible an...read more

Agile process is a project management approach that emphasizes flexibility, collaboration, and incremental delivery.

• Agile process involves breaking down projects into small increments called sprints

• It prioritizes customer collaboration and responding to change over following a strict plan

• Common methodologies include Scrum, Kanban, and Extreme Programming (XP)

• Regular meetings like daily stand-ups and retrospectives are key components of agile process

Software development life cycle is a process used by software development teams to design, develop, test, and deploy software.

• SDLC consists of several phases such as planning, analysis, design, implementation, testing, and maintenance.

• Each phase has its own set of activities and deliverables.

• Common SDLC models include Waterfall, Agile, and DevOps.

• SDLC helps ensure that software projects are completed on time, within budget, and meet user requirements.

Debugging is the process of identifying and fixing errors or bugs in software code.

• Debugging involves tracing and isolating the root cause of a problem in the code.

• Common debugging techniques include using print statements, breakpoints, and debugging tools.

• Debugging helps ensure that the software functions correctly and meets the desired requirements.

Dependency injection is a design pattern that allows objects to be injected with their dependencies rather than creating them internally.

• Dependency injection helps to decouple the code and improve testability and maintainability.

• It promotes loose coupling by allowing objects to depend on abstractions instead of concrete implementations.

• There are three common types of dependency injection: constructor injection, setter injection, and interface injection.

• Example: Instead of cre...read more

A stored procedure is a precompiled set of SQL statements that can be executed on a database server.

• Stored procedures are used to encapsulate and execute complex database operations.

• They can be written in various programming languages like SQL, PL/SQL, T-SQL, etc.

• Stored procedures can accept input parameters and return output values.

• They can be used to improve performance by reducing network traffic and optimizing query execution.

• Examples: sp_GetCustomerDetails, sp_InsertEmpl...read more
