1. Introduction
1.1 Background
Modern software contains hundred lines of code and can be developed by several developers at the same time. Based on that, the need of a version control system that keeps track of the work and controls it, becomes crucial (Ruparelia N., 2010). This vital role of version control system could contribute in improving the performance, on the other hand, it could be a source of frustration (Rosso and Jackson, 2013).
The history of version control systems emerged as a Local Version Control Systems at the beginning. These systems used mainly to copy files into another directory. Thereupon Centralized Version Control Systems appeared and made it feasible to collaborate with developers from other systems. These system implemented by having a single server that contained all the versioned files and a number of clients. In order to avoid the drawbacks of centralization, Distributed Version Control Systems, Git is one of them, developed. These systems allow the clients to have their own copies of the whole repository.(Chacon, 2009).
ClearCase and Git are two of the most known version control systems. The former launched in the 1990s by IBM which supports parallel and geographically-distributed software development (Allen L. et al., 1995). While the later launched 2005 and adopted by Linux developer as a free and open-source distributed version control system (Ruparelia N., 2010).
According to O’sullivan (2009), the choice of a version control system is a significant process for each company that needs it. It should suit the type of work which done by the company. Moreover, as a software developer replacing one version control system with another might affect the development environment. For instance, replacing ClearCase with Git might involve challenges and benefits. One study which conducted by De Rosso and Jackson (2013) tried to shed the light on the root causes of Git’s complexity by analyzing its conceptual model and identifying some undesirable properties. Yet, there is no research has been done to address the differences between these two systems or the difficulties and the benefits that associated with each one of them. This lack of knowledge arise the question about how to tell if this replacement is a step toward a better development environment or not. Yet if these benefits and challenges addressed clearly, then the questions could be answered easily.
1.2 Research objectives
This study described the potential practical benefits and drawbacks that resulting of using Git instead of ClearCase as a version control system from software developers point of view.
The Software Development Life Cycle is seldom used at my place of work. Unfortunately, recent developments in its use are deemed confidential. Due to this fact, this paper will examine in general terms one of the projects we are undertaking right now while at the same time attempting to maintain our confidentiality.
Standardize procedures and project management. E.g. use the same language or coding and decoding of software.
Github is a way for people to share open source code. It is a powerful and sophisticated repository web-system for developing software projects. It uses “Git revision control” system. It offers both paid plans for private repositories and free accounts for open source projects [1]. GitHub was the most popular and famous code repository site for the open source projects. GIT is developed by Linus Torvald. Before going in the core explanation of GitHub it’s better to describe the term “version control” system. It can be a designer or a person who works with code or the developer. They all have few multiple common tasks as:
Maintain a shared efficient filing system. Led a project to develop and streamline paper files, minimizing need for physical files by 70% and reducing research time by 80%.
Backup copies are processes that are used to save information. It is to say, a user wants to save all the information or part of the information available on the PC up to this moment; will make a backup copy in such a way that it will save the information in some technologically available storage, the urgent care clinic, the Systems area has two of the Servers as Backups administrator (Allen 2004)[2]; for later if a loss occurs in the computer equipment of one of the users and information is lost, from the Systems area the process of restoring the information to the date of the last backup made by the end user can be performed. In order for the process to be functional, users must periodically complete the process according to the indications given by the Systems
b.Identify appropriate project management tools and describe how they can be accessed. Provide an example of the tool and outline how it relates to your project.
It is well known that the team work is far better than performing a task individually. Such kind of practice plays a very important role in software engineering. A lot of things can be achieved together with the combination of diversified people, as they input different tactics and skills so that the main objective of a certain mission can be accomplished appropriately. Even though teaming up and working for a project is essential and helpful; there exist some issues that could bring interruptions and conflicts in the team.
Detailed requirements that a small organization (less than 50 employees) can use to select project management software.
Early fixing of errors not only helps save cost but also helps in mitigating the various risks associated with software development and it also helps in improving and monitoring quality of the system etc. It has been proven that the cost to identify and mitigate the errors in the early stages of development of a software will be hundred times less than the cost of removing an error in the software system that has been distributed among hundreds of
The Systems Development Life Cycle (SDLC) consists of phases used in developing a piece of software. It is the plan of how to develop and maintain software, and when necessary, replace that software. In 2007 during my hospital’s transition to a new software system, I was fortunate enough to be included in the process. I did not get involved until the implementation phase, but from then on, until now, I remain very active in the process. I decided to highlight the Waterfall Model of SDLC. The Waterfall Model is a “sequential development process” with each phase continuing in a line (McGonigle and Mastrian, 2012, p. 205).
There are three methods of source control that are directed in limiting the planting and manufacturing of illegal drugs in foreign countries. They are crop eradication, control of precursor chemicals, and the U.S. certification process. Crop eradication focuses on the reduction of agricultural output of opium poppies, coca plants, and marijuana from their respective countries of origin. The eradication of the crops is done both manually and through the use of herbicides that kill the plants. The theory is that by decreasing the cultivation for the manufacturing of the illicit drugs, it in return causes the drugs to be more expensive, thereby reducing the level of drug use. Despite the theory, growers have found ways around the crop eradication, so the method proved to be successful for a limited period (Levinthal, 2012).
Linux has long been one of many operating systems that have been out to prove its worth in all types of environment. It is currently being considered for enterprise network purposes as well as data centers where it implies servers, workstations and any mainframes as needed. Choosing what operating system to use, whether it is open source or not, can be difficult, though. This paper projects the advantages and concerns of choosing an open source solution like Linux as administrators and users are becoming more aware of Linux running on both server and desktop systems. It is quickly being adopted in an ever increasing number of global corporations and government agencies.
Every organization has unique reasons for automating software quality activities, but several reasons are common across industries.
It simplifies the storage and processing of large amounts of data, eases the deployment and operation of large-scale global products and services, and automates much of the administration of large-scale clusters of computers.
