Software development projects have been blamed for being behind schedule, cost overruns, and the delivery of poor quality product. This paper presents a simulation model of a data warehouse to evaluate the feasibility of different software development controls and measures to better manage a software development lifecycle, and improve the performance of the launched software. This paper attempts to address the practical issue of code defects in each stage of data warehouse application development. The author has compared the defect removal rate of their previous project to the newly proposed enhanced project development life cycle that uses code inspection and code scorecard along with other phases of software development life cycle. Simulation results show that the code inspection and code score-carding have achieved a significant code defect reduction. This has also significantly improved the software development process and allowed for a flawless production execution. The author proposes this simulation model to a data warehouse application development process to enable developers to improve their current process.

Abstract: The Software Development Life Cycle (SDLC) refers to a methodology with clearly defined processes for creating highquality software which are cost effective and reliable. This method of software developing process is quite systematic and structural. SDLC defines the framework that has different activities and tasks to be administered during the software development process. Software development process is quite complex, and to do it without any proper planning would be inefficient. So, we use these SDLC models to make the Software development process simple and systematic. There are various software development life cycle models that are used in the software development process, all having their own advantages and limitations. In this paper, we have included six of these SDLC models - Waterfall Model, Spiral Model, V Model, Agile Model, Iterative Model and Rapid Application Development (RAD) Model. These Software Development processes have their own Advantages and Disadvantages, and the main purpose of this paper is to explain these models and know the difference between them.

This paper takes a deeper look at data breach, its causes and the linked vulnerability aspects in the application development lifecycle. Further, the Vulnerabilities are mapped to the software development life cycle (SDLC) involving requirement elicitation, design, development, testing and deployment phases. Being aware of exact SDLC life cycle where the vulnerabilities are injected, suitable security practices (countermeasures) can be adopted in delivery methodology, which can control the eventual data breaches and safeguard the application from security perspective. Our research focuses on Evolution of Vulnerabilities through the application development life cycle, and we have leveraged “Inverted Tree Structure/Attack Tree” and “Affinity Principles” to map the vulnerabilities to right Software Development Life Cycle.

With the adaptation of DevOps and agile methodologies for software developments, the demand from the consumers of the software applications are increasing to fulfil short time development phases. The application development community is facing the everlasting challenge of managing the bottleneck of timely delivery and quality of the software. The software quality being one of the most important factors to maintain the market reputation and the customer satisfaction, cannot be compromised. The software development companies have also tried adopting the strategies of deploying highly skilled development team in order to reduce the development life cycle span. Thus, several research attempts are made to identify the correct software reusable components for any projects. Nonetheless, the recent research outcomes are challenged by the development community with the arguments of reliability as different applications from different domain demands unique specifications and standards to be matched. Also, the components, which are to be reused for other specifications, must match the compliances of that specification. Considerably, identification of the reusable components is always a challenge and it is observed that the identification of the flexible components, for which matching the domain specification is easy, is also high complex process. Finally, finding the ideal coupling point of the identified modules are also a significant challenge. Thus, this research proposes a novel framework for identification of the flexible components for reuse in software development life cycle and identifies the unique coupling points of these components. Firstly, this work analyses the software components for features to be identified as flexible components using the deep extraction algorithm. The deep extraction algorithm demonstrates a novel characteristic for extracting feature based on the external and internal feature dependencies. The extracted features are also ranked based on the degree of independency and finally listed based on given ranks for reusability. Secondly, the extracted features are tested for outcome-based equivalence to ensure best reusability from the component library. Due to the multi – level equivalency analysis, this proposed framework provides higher accuracy and lower time complexity using the moderate number of extracted features for component analysis.

The development of high quality software is the need of current technology driven world. Component Based Software Engineering (CBSE) has provided a cost effective, fast and modular approach for developing complex software. CBSE is mainly based on the concept of reusability. Apart from these CBSE has several advantages as well as challenges which are summarized in this paper. Large and complex software development requires management of reusable components and can be selected from component repository and assembled to obtain a working application. Development of components and their assembly is different from traditional softwares which leads to the need of new development paradigms for Component Based Systems (CBS). Software development life cycle (SDLC) provides planned and systematic arrangement of activities to be carried out to deliver high quality products within time and budget. This paper presents a comparative study of component based software development life cycle models with their strengths and weaknesses.
