Individual Assignment: Design Patterns
CSS/422
Design Patterns: Introduction
There are lots of design styles readily available for the creation of company software program. The design styles talked about in this report will include Data Access Object (DOA), dispatcher, plant technique, abstract factory method, as well as model-view-controller (MVC). All 5 of these design styles are evaluated as well as compared in this report.
Data Access Object (DAO)
The data access object (DAO) software program design pattern encapsulates use of data by concealing its difficulty from end users (University of Phoenix, 2005). This design pattern is a concept offering an abstract interface to a database or perseverance method, which it only provides a few specified functions excluding the visibility of the database particulars. The DAO includes a mapping from the software calls to its perseverance layer that isolates the general public interface of the DAO.
Dispatcher
The dispatcher software program design pattern manages customer access and re-directs or dispatches customer requests to the appropriate party which can be situated on the exact same or different tier (University of Phoenix, 2005). This design pattern helps the workflow execution since the customer requests are forwarded to the correct party.
Factory Method
The plant method design pattern generates a group of connected items instantiated by subclasses (University of Phoenix, 2005). This design pattern generates items without indicating the category of item that's to be generated. The plant method pattern describes a different way of producing items by using subclasses to override the derived kind of item that's to be generated.
Abstract Factory Method
The abstract plant method design pattern resembles the plant method; however it provides a dimension to the plant method. The abstract plant method pattern generates a group of families that is what adds the dimension (University of Phoenix,
