Software Development

Software Development Agile Agile is an insurance policy for market changes. By designing your solution according to this methodology, your project remains flexible and is always ready for change. It is always better to correct the mistake early in the process. With this method, you keep your finger on the pulse of a dynamic market and changing user expectations. As a result, you can continuously adapt, change your strategy, and create a product that will be in demand by the target audience, even if preferences have changed during the development process. DevOps DevOps is one more way to optimize the development budget of your application. A key DevOps approach is that this practice and its culture allow team members to better interact with each other and the customer. The software development team and those responsible for the operation of the application share responsibilities clearly, and it helps you avoid shifting responsibilities from one team member to another. DevOps involves th...

Abstract Factory Pattern

Abstract Factory Pattern Gamma Categorization: Creational Design Patten Summary: When the object construction is complicated, needing multiple arguments, we should create a separate function (Factory Method) or class (Factory), which is responsible for the creation of the all object. Problem examples Suport of multiple databases Multiple data sources: Serial port, ethernet port, device driver Diferent report types Solution Abstract class Generalized interface A Factory creates instances of the concrete classes Sample Code The abstract factory public interface IPhotoFactory { IAnaloguePhoto CreateAnaloguePhoto (); IDigitalPhoto CreateDigitalPhoto (); } The abstract products public interface IAnaloguePhoto { string GetName (); } public interface IDigitalPhoto { ...

SOLID (3/5) - Liskov substitution principle

SOLID (3/5) - Liskov substitution principle Substitutability is a principle in object-oriented programming stating that, in a computer program, if S is a subtype of T, then objects of type T may be replaced with objects of type S (i.e., an object of type T may be substituted with any object of a subtype S) without altering any of the desirable properties of the program (correctness, task performed, etc.). More formally, the Liskov substitution principle (LSP) is a particular definition of a subtyping relation, called (strong) behavioral subtyping. It is a semantic rather than merely syntactic relation, because it intends to guarantee semantic interoperability of types in a hierarchy, object types in particular. using System ; namespace Liskov { public class Rectangle { //public int Width { get; set; } ...
