Question

Software design uses patterns. Research software design patterns. Note that these are not software development methods. They are patterns used in the actual software itself.

Give examples of common software design patterns.

Discuss the benefits of software design patterns.

Design patterns typically focus on a specific area. There is another pattern, however, that is very general and all encompassing. Because of its broad applicability, I call it the Primary Pattern. It is most often referred to as the Input-Process-Output (IPO) pattern. This pattern presents a system/program as a sequence consisting of the following steps:

Discuss why this pattern has such broad applicability.

Give examples of this pattern in the business world.

Give examples of this pattern in computer hardware.

Discuss the kinds of actions that may be performed by each of its 3 steps.

Explanation / Answer

Design patterns have two main usages in software development

So these patterns can be used as a common pattern for developers : because these patterns provide a standard terminology and are specific to particular scenario.

Example:

If a singleton design pattern signifies use of single object so all developers familiar with single design pattern will make use of single object and they can tell each other that the program following a singleton pattern

In best practices:

Design patterns have been evolved over a long period of time and they provide best solutions to certain problems faced during software development. learning these patterns helps un-experienced developers to learn software design in an easy faster way

Types of design patterns :

Over all 23 types of design patterns are there but all of them are categorized into 3 categories

1. creational

2. structural

3. behavioral patterns

2. Advantages of design patterns :

Enables large scale reuse of s/w

Helps in improve developer communication

Captures experts knowledge and design trade-offs and make expertise widely available

A standard solution to a common programming problem

A technique for making code more flexible by making it meet certain criteria

A design or implementation structure that achieves a particular purpose

3. these design patterns have broad applicability why because we have 23 patterns which can useful in different ways in a broad way

For business we can use them to enhance our business

In software and also hardware we can use them

Based on the catagories we can filter our needs and optimize the performance also

4..for business patterns they are like

Total business activities do get outsourced: there are countless examples where business functions ,units and services have been outsourced to third parties like ADP.

There would be consistent design patterns for these types of business functions that can be used across industry and organizations

International as well as global organizations create satellite offices: these are mainly focuses on operationalize growth through organic growth

Asset stripping is still a reality: one and only has to look at the M&A news or current public sector initiatives to witness large business functions being stripped from the organization
