The Phases Of Software Life Cycle From The Simula 67

“During the object-oriented analysis (OOA) phase object-modeling techniques are used to analyze the functional requirements for a system and create models which reflect the logical design of the system. During the object-oriented design (OOD) phase of the system, models are elaborated upon to include implementation specific details that show how the physical design of the system will come together. OOA focuses on what the system does (its static structure and behavior), OOD on how the system does it (its run-time implementation).”

Programming languages are vast and diverse in their numbers. These different languages use fundamental styles of programming called programming paradigms. These programming paradigms layout the particular design approach that a program will use to solve a problem or achieve an objective. Of the many different types of programming paradigms, some of the more distinguished ones are procedural, functional, logical, and object orientated programming. Recently the object orientated languages have been rising in popularity due to their ability to easily implement large programs. There are many different object orientated programming languages (OOPLs), among them are C#, Java, Ruby, and Python. This essay will compare and contrast two of these languages: Python and Java.

The focus of object-oriented view is on the elaboration of design classes that belong to both problem and infrastructure domains. Classes are elaborated by specifying messaging details, identifying interfaces, defining attribute data structures, and describing process flow for operations. In traditional view, three components are refined, they are control modules, domain modules, and infrastructure modules. To generate programming language source code detailed representations of data structures, interfaces and algorithms for each program are to be created.

Identify 4 different stages of the Software Development Life Cycle (SDLC) and explain how requirements are used in each stage of the SDLC.

The software development life cycle is utilized by the software industry to design, develop, and test software. The objective of the SDLC is to provide high quality software that exceeds customer expectations and meets timeframes and cost expectations. This paper will provide a brief overview of the SDLC and the various stages throughout the life cycle. There are various SDLC models such as the waterfall, agile, and rapid development. The writer will describe traditional waterfall method utilized at his current place of employment and discuss areas for improvement.

After the organized philosophies, programming improvement methodologies developed into Object-Oriented (OO) approachs. They incorporate the

The modern programming is based on the concept that “program little and use more”. The object oriented programming languages are playing a vital role in the industry of development. The OOP introduced following concepts:

Amongst the various processes in the Software Development Life Cycle, Software Testing is the one which ensures the quality of the product or service is maintained and Automated Software Testing is the most efficient way of doing it. This paper focuses on the importance of automated software testing, its benefits in software engineering and some of the prominent techniques for test automation. Automated Testing is in a huge demand in the current business world due to its efficient and cost effective techniques. There is an urge for enhanced software development in the current Information Technology Industry and that there has to be a testing technique to match that development. Automated software testing is a process by which fast, proficient and low cost testing can be achieved with a significant low manual work. It prevents the steps of manual test cases and generates automated test scripts using an automated software tool to shorten the testing life cycle with respect to time as well as cost.

OOP, an abbreviation for object-oriented programming is simply code that “attempts to place a new layer of abstraction between the programmer and the data he is working with … this layer will help the programmer develop better code more quickly than he could do before.” (McHale). OOP languages must include four

The software development life cycle is the cycle in which software is developed. It is a process that has been improved upon as programming has expanded and become a bigger part of computers and networking. Programming is necessary in order to enable computers to perform in a desired manner, and those computers rely on that programming as instructions in order to function. Since computers rely on their programming to know how to function, the programming needs to be as efficient and flawless as possible, in order to produce ideal results. The software development life cycle is a tool used to help achieve ideal results.

Smalltalk was developed at Xerox PARC by Alan Kay and others in the 1970s. The term object-oriented programming was introduced to represent the extensive use of objects

In this programming language we have to understand the meaning of various terms such as objects, class, data abstraction and encapsulation, inheritance (one of the most powerful concept), polymorphism, data binding, and message passing etc.

Object-oriented approach was developed in late 1950’s in MIT to overcome the drawbacks of procedural- oriented approach. Ii is commonly known as OOPS. Now, it has become most preferred programming approach by software engineers to solve real world complex problems. The traditional procedural languages solve problems in terms of the structure of the computer i.e. memory bits and bytes, array, decision, loop rather than thinking in terms of the problem which is to be solved.
