It also defines business rules for data means how the data can be changed and manipulated. business model as well as data access operations i.e. The Model represents a set of classes that describe the business logic i.e. The three most commonly used Architectural Patterns in Android are Lack of an architecture that supported the flexibility that we needed.Īrchitectural patterns are used to overcome these problems.

Two main reasons for many codes to be in such bad shape is,Ģ. These design patterns are specifically concerned with communication between objects. The concept of inheritance is used to compose interfaces and define ways to compose objects to obtain new functionalities. These design patterns concern class and object composition. This gives the program more flexibility in deciding which objects need to be created for a given use case. These design patterns provide a way to create objects while hiding the creation logic, rather than instantiating objects directly using the new operator. They are highly flexible and can be used in practically any type of application or domain.They have a proven track record as they are already widely used and thus reduce the technical risk to the project.They aid communication by the very fact that they are well documented and can be researched if that is not the case.They are language neutral and so can be applied to any language that supports object-orientation.They give the developer a selection of tried and tested solutions to work with.It won’t be the exact solution whereas it would just give a template to solve a solution.

A design pattern can be defined as a general repeatable solution to a commonly occurring problem in software design.
