The structured approach got accepted and started being widely used for development and system analysis. Then, a methodology was created that helped the development of applications with the object oriented languages. This approach came to be known as the object oriented analysis and design. A comparative analysis has been conducted with respect to these two methodologies, along with their basic infrastructure and techniques.
The structured approach enables the analyst to split a complex project into smaller and controllable parts. This approach is based on the step-by-step execution of the phases. The start of an activity in a phase will depend on the completion of activities in the preceding phase. It is based on a top-down, hierarchal approach that produces logical and organized systems (Holon Institute of Technology, n.d.). The structured nature of the design facilitates efficient project management, resource management etc.
OOAD approach follows an object oriented approach instead of a functional one that is followed in SSAD (Pefkaros, 2008). An object in OOAD is considered to be any place, person or thing that can have the following aspects related to it;
Structured approach promotes the concept of clear steps from the initiation of the project till the end; these steps are conventionally planning, analysis, design and implementation. Whereas the object oriented approach does provide any such specific number of phases. There are no clear steps from analysis to design.
Structured System analysis and design is process oriented whereas object oriented system and design is data-oriented. There exists a clear separation between the between the data and the processes of the system in the structured approach, while the data and the processes of the system are encapsulated into objects (Pefkaros, 2008).
OOAD seems more flexible and adaptive to changes as compared to SSAD. There can be many benefits gained from ...

The primary task of any manager is to prepare an organization that functions effectively. In order to achieve this each and every employee needs to work with full dedication and efficiency. To increase the employee performance motivation is a crucial part.
In other words, fulfillment or gratification of any desire can also be termed as ‘satisfaction.’ According to Zethimal et al. (1993), satisfaction is considered to be the outcome that is derived when desired services and perceived services are compared.
Software systems are continuously improved, advanced, or sophisticated to suit different users in the respective fields of application. In this pursuit, software architecture comes in to define, provide and aid the process through system designs that enhance software application across the various fields of computation.
The object oriented programming refers to a form of programming style or paradigm whose foundation is the representation of the programming concepts as objects. Each object in this form of interaction is referred to as an instance of a particular class of objects. In this paradigm, objects are those instances that are used to represent concepts.
In fact, in the UK its practice is frequently mentioned as a requirement for government sector computing projects. In view of the fact that this software development methodology was developed for the CCTA, which is a UK government office deals with the use of technology in government, from 1980 onwards for this reason it is more and more being followed by the public sector projects and organizations in Europe.
It is also the study of physiological and neurobiological processes that influence certain cognitions, emotions, brain functioning, personality, behavior and interpersonal relationships. Psychology seeks to understand and explain how people think, act and feel with an aim of improving peoples’ lives by enhancing their performance, productivity, self-determination and motivation.
A program or a comprehensive set of instructions that is designed to achieve a particular objective is referred to as a function or a method. These functions always work on related data. There are two paradigms that are followed to write computer programs: ‘procedural’ or
System design paradigms are a fundamental area of software design that is intended to provide a framework for capturing, storing, manipulation and dissemination of information (Downs & Coe, 1992).
