Dependency Inversion and Inversion of Control
Dependency Inversion
The Dependency Inversion Principle states that:
- High level modules should not depend upon low level modules. Both should depend upon abstractions.
- Abstractions should not depend upon details. Details should depend upon abstractions.
Git basic commands Cheat Sheet
Git is a powerful system for distributed version control.
HTTP vs HTTPS. Key differences.
Hypertext Transfer Protocol - No Data Encryption
The Hypertext Transfer Protocol (HTTP) is an application-level protocol
Design Patterns (Java)
The design patterns are strategies for solving common object-oriented design problems. Using the design patterns you can make your code more flexible, reusable and maintainable. We must use the design patterns during the analysis and requirement phase of SDLC (Software Development Life Cycle).
Standard Diagrams (UML)
UML – The Unified Modeling Language (UML) is a general-purpose, developmental, modeling language in the field of software engineering, that is intended to provide a standard way to visualize the design of a system.
Web Services
A Web Service is a software application identified by a URI (Uniform Resource Identifier) whose interfaces and binding are capable of being defined, described and discovered by XML artifacts and [that] supports direct interactions with other software applications using XML based messages via Internet-based protocols (HTTP, HTTPS, SMTP).
Aspect-Oriented Programming
AOP aims at reducing the amount of "tangled" code by which we mean code that might be implemented in different classes if a OOP language is used but still share important secondary requirements. Such requirements are said to cross-cut the system's basic functionality and are difficult to develop and maintain using non-AOP programming paradigms. Cross-cutting functionality can be thought of as functionalty spanning many objects.
